endobj Quiz Ref IDUse of computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound in the United States increased rapidly from 2000 to 2006.1,2 Among Medicare beneficiaries, the increase in utilization was higher for medical imaging than other physician-provided services.3,4 Steep increases in imaging can be attributed to technical improvements, physician and patient demand, and strong financial incentives. et al. The US health care systems are members of the National Cancer Institutesupported Health Care Systems Research Network,12 and all sites have available electronic health care information stored in a virtual data warehouse.13,14 The virtual data warehouse is a collaborative data model structure consisting of a series of data tables with information on all medical care utilization, including imaging, among enrollees. There are now special MRI machines that have a bigger opening to make the imaging more accessible for everyone. Imaging trends in children were similar to adults, with the notable exception of a recent decline in CT. For CT, imaging rates increased most rapidly in the early 2000s; the annual percentage change in CT was 10.1% in the United States (2000-2005) and 3.3% in Ontario (2000-2006). Over 10,000 hospitals worldwide use radioisotopes in medicine, and about 90% of the procedures are for diagnosis. Medical technology - top companies based on revenue 2021, Number of investments in high tech companies in Italy 2020, by category, Medical technology market share based on manufacturer prices in Europe 2021, Life science patents granted by the European Patent Office in Italy 2022. Centers for Medicare & Medicaid Services. Half a century ago, the first CT image of a patient lifted the veil of invisibility that . Ultrasound imaging increased over time, with less variation in annual growth over time across adults and older adults (range, 0.4% to 7.6%) than observed for CT and MRI (Figure 1 and eFigure 1 in the Supplement). The focus is primarily on CT because of the relatively high ionizing radiation exposure per examination and large numbers of individuals exposed.29 Adults and children are sensitive to radiation.30-33 In adults, CT use continued to rise, albeit more slowly than seen previously. Whether the observed imaging utilization was appropriate or was associated with improved patient outcomes is unknown. You only have access to basic statistics. Please create an employee account to be able to mark statistics as favorites. van Walraven Question A permutation test was used to select the best model and determine the number of joinpoints for each subgroup, applying a Bonferroni correction to the type I error to correct for multiple testing. Annual and relative imaging rates by imaging modality, country, and age (children [<18 years], adults [18-64 years], and older adults [65 years]). All US data are shown as solid curves; Ontario data are shown as dashed curves. This study examined medical imaging rates from 2000 through 2016 among individuals enrolled in diverse US integrated health care systems and among individuals residing in Ontario, Canada, and assessed changes in medical imaging utilization over time by country, health system, and patient demographic factors. September 5, 2008. Second, the indication for imaging was not available; thus, it is not possible to determine whether imaging was appropriate or inappropriate for any given test or whether imaging utilization was associated with improved patient outcomes. Patterns in Ontario were similar. This may suggest that imaging rates are lower within systems that have stronger incentives to constrain imaging (and cost). These data sets were linked using unique encoded identifiers and analyzed at ICES, Toronto, Ontario, before being aggregated with the US data at the University of California, Davis. The recent losses in Medicare imaging revenues experienced by radiologists, cardiologists, and other physicians. MRIs use magnetic force instead of radiation, making them a more popular option for many who are wary of tests that use radiation. Raja In 2016, in most anatomic areas imaged with CT or MRI, imaging rates were higher in the United States compared with Ontario (Table 3). OECD. What were the trends in medical imaging from 2000 through 2016 in the United States and Ontario, Canada? For Ontario, the Registered Persons Database was used to identify an eligible population. Use of MRI in each anatomic area increased in Ontario between 2012 and 2016 (overall annual growth, 2.5%; head, 2.2%; spine, 3.5%), whereas in the United States there was no significant growth during this period. In the United States, CT increased from 18 to 22 per 1000 person-years (relative rate, 1.2; 95% CI, 1.1-1.3), MRI increased from 9 to 21 per 1000 person-years (relative rate, 2.3; 95% CI, 2.0-2.5), and ultrasound increased from 30 to 59 per 1000 person-years (relative rate, 2.0; 95% CI, 1.8-2.2). <> To use individual functions (e.g., mark statistics as favourites, set C, Austin Most people today are used to the existence of imaging tests and the machines used to perform them. Some billing codes changed over time, and all codes were mapped to an anatomic area and imaging modality to ensure consistency over time, updating a previously used map.2 For Ontario data, Canadian Classification of Health Interventions19 codes were used to create a relational table of codes from the United States with codes from Canada to compare imaging rates by imaging modality and anatomic area. Retrospective cohort study of patterns of medical imaging between 2000 and 2016 among 16 million to 21 million patients enrolled annually in 7 US integrated and mixed-model insurance health care systems and for individuals receiving care in Ontario, Canada. This dye helps your doctor see the MRI picture more clearly. Results Parts of this material are based on data and/or information compiled and provided by the Canadian Institute for Health Information. Annual growth in imaging rates among US adults and older adults slowed over time for CT (from an 11.6% annual percentage increase among adults and 9.5% among older adults in 2000-2006 to 3.7% among adults in 2013-2016 and 5.2% among older adults in 2014-2016) and for MRI (from 11.4% in 2000-2004 in adults and 11.3% in 2000-2005 in older adults to 1.3% in 2007-2016 in adults and 2.2% in 2005-2016 in older adults). endobj But few people know the history and the importance of certain imaging machines, especially if they dont work in the medical field. Doctors can then identify each type of tissue, bone, joint, muscle and cartilage based on the signal recorded on the MRI scan. IK, Sodickson Deficit Reduction Act of 2005, S 1932, 109th Cong. In 2016, relative imaging rates for specific anatomic areas were as follows: for CT of the head, relative rate, 2.14 (95% CI, 1.95-2.35; 9.8 per 1000 person-years in the United States vs 4.6 per 1000 person-years in Ontario); for CT of the spine, relative rate, 2.96 (95% CI, 2.60-3.36; 1.8 per 1000 person-years in the United States vs 0.6 per 1000 person-years in Ontario); for CT of the chest, relative rate, 1.32 (95% CI, 1.19-1.48; 1.3 per 1000 person-years in the United States vs 1.1 per 1000 person-years in Ontario); for CT of the abdomen, relative rate, 4.06 (95% CI, 3.59-4.59; 5.6 per 1000 person-years in the United States vs 1.4 per 1000 person-years in Ontario); and for CT of the extremities, relative rate, 1.22 (95% CI, 1.08-1.37; 0.9 per 1000 person-years in the United States vs 0.8 per 1000 person-years in Ontario). It includes estimates of GP usage of direct access to key diagnostics tests for cancer, for example chest imaging, non-obstetric ultrasound and Brain MRI. The next most common procedures were Diagnostic Ultrasonography (Ultrasound, 0.77 million), Computerized Axial Tomography (CT Scan, 0.40 million) and Magnetic Resonance Imaging (MRI, 0.28 million). Calendar year and country (United States vs Canada). To evaluate recent trends in medical imaging. In addition, what is acceptable clinical practice changes over time. In the United States, CT imaging during the next period continued at a slower pace (0.7% annual growth between 2005 and 2009), followed by a large reduction in imaging (9.1% annual growth), followed by relative stable imaging after 2013 (0.8% annual growth; 95% CI, 3.6% to 5.5%) (Figure 1 and eFigure 1 in the Supplement). In children, imaging rates continued to increase except for CT, which stabilized or declined in more recent periods. Critical revision of the manuscript for important intellectual content: All authors. Before a test begins, the magnets must be cooled to absolute zero. <> Among the global top manufacturers of MRI scanners are General Electric, Siemens, Hitachi, and Philips. For example, in the US health care systems, CT imaging increased from 56 per 1000 person-years in 2000 to 141 per 1000 person-years in 2016, MRI from 16 to 64 per 1000 person-years, ultrasound from 177 to 347 per 1000 person-years, and nuclear medicine from 28 to 22 per 1000 person-years (Table 1). Quiz Ref IDFirst, the study was limited by including US patients enrolled in a limited number of health care systems, all of which used HMO models of care either in part or in total. Cancer risks after radiation exposure in middle age. Retrospective cohort study of patterns of medical imaging between 2000 and 2016 among 16 million to 21 million patients enrolled annually in 7 US integrated and mixed-model insurance health care systems and for individuals receiving care in Ontario, Canada. Imaging rates for CT among adults and older adults increased most rapidly in the early 2000s; in adults, annual growth in CT was 11.6% in the US sites (2000-2006) and 9.2% in Ontario (2000-2007), and in older adults, annual growth was 9.5% in both the United States (2000-2006) and Ontario (2000-2007). Nikola Tesla discovered rotating magnetic fields. Considering the massive amount of MRI scans done every year, it's not surprising that the workforce of MRI technologists is estimated to grow by 9% between 2018 and 2028. HS, Feuer These sites were selected to provide a sample of US health care systems with sociodemographic and geographic diversity. MRI scans are very noisy so you wear ear plugs or headphones. Statista. Annual percentage changes and 95% confidence intervals were estimated assuming that the rates change at a constant percentage every year on a log scale. The absolute rates of ultrasound imaging were higher than for CT and MRI combined among both adults and older adults. First, the study was limited by including US patients enrolled in a limited number of health care systems, all of which used HMO models of care either in part or in total. The ideal entry-level account for individual users. For example, in the US health care systems, CT imaging increased from 56 per 1000 person-years in 2000 to 141 per 1000 person-years in 2016, MRI from 16 to 64 per 1000 person-years, ultrasound from 177 to 347 per 1000 person-years, and nuclear medicine from 28 to 22 per 1000 person-years . A modification of the Elixhauser comorbidity measures into a point system for hospital death using administrative data. CT indicates computed tomography; MRI, magnetic resonance imaging. Jr, Horwitt Annual imaging rates by imaging modality, age, and country are shown in Table 2. The patterns were similar by anatomic area, with declines or no change between 2006 and 2016, except for spine imaging in the United States. "Number of Magnetic Resonance Imaging (Mri) Units in Selected Countries as of 2019 (per Million Population). However, these differences were not seen to the same degree in older adults. Use Ask Statista Research Service. Quiz Ref IDIdeally, use of any health care service should be guided by a balanced consideration of benefits and harms, yet for imaging, few relevant data quantifying either are available. HJ, Luo Statistical analysis: Marlow, Cheng, Pole, Miglioretti. Pub L No. et al. Utilization rates were modeled using overdispersed Poisson regression including main effects for examination year, country, and US system and an interaction term between examination year and country. Changes in annual growth in ultrasound were smaller among adults and children in the United States and Ontario. From 2000 to 2016 in 7 US integrated health care systems and Ontario, CT and MRI rates continued to increase among adults, but at a slower pace in more recent years compared with earlier years; in children, CT rates stabilized or declined in recent years. Ideally, use of any health care service should be guided by a balanced consideration of benefits and harms, yet for imaging, few relevant data quantifying either are available. 2019;322(9):843856. In children, imaging rates continued to increase except for CT, which stabilized or declined in more recent periods. Overall, 135774532 imaging examinations were included; 5439874 (4%) in children, 89635312 (66%) in adults, and 40699346 (30%) in older adults. Among children, annual growth for CT stabilized or declined (United States: from 10.1% in 2000-2005 to 0.8% in 2013-2016; Ontario: from 3.3% in 2000-2006 to 5.3% in 2006-2016), but patterns for MRI were similar to adults. Joinpoint regression20,21 was used to identify years with significant changes in imaging trends over time and to calculate the average annual percentage change (growth) within fixed time periods (2000-2005, 2006-2011, and 2012-2016) by imaging modality and anatomic area. Brain (MRI) This may diagnose brain cancer, this includes - MRI of brain (often with contrast); Kidney or bladder (Ultrasound) This may diagnose kidney or bladder cancer, this includes - ultrasound of kidney, ultrasound scan of bladder or ultrasound and Doppler scan of kidney; Chest and/or abdomen (CT) Calendar year and country (United States vs Canada). Overall, 135774532 imaging examinations were included over 310093012 person-years; 5439874 (4%) in children (49.5% female), 89635312 (66.0%) in adults (50.8% female), and 40699346 (30%) in older adults (50.0% female) (Table 1). This animation shows a 3-D rendering of a whole-body positron emission tomography (PET) scan identifying the location of a cancerous tumor . A notable exception was a decline in CT use in children in recent years. Use of diagnostic imaging studies and associated radiation exposure for patients enrolled in large integrated health care systems, 1996-2010.

It is possible that the greater use of ultrasound in Canada reflects its more frequent use in pregnancy; however, this would only affect and explain imaging in adults and not imaging in children and older adults. Author Contributions: Dr Miglioretti had full access to all of the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis. There was ongoing but slower annual growth in MRI during the most recent periods (1.3% in adults [2007-2016] and 2.2% in older adults [2005-2016] in the United States and 4.3% in adults [2008-2016] and 4.9% in older adults [2010-2016] in Ontario) (Figure 1 and eFigure 1 in the Supplement). For children, imaging rates were significantly higher in the mixed-model plans for CT (23.5 vs 14.6 per 1000 person-years; relative rate, 1.61; 95% CI, 1.45-1.78), MRI (22.2 vs 17.6 per 1000 person-years; relative rate, 1.26; 95% CI, 1.16-1.37), ultrasound (63.3 vs 45.6 per 1000 person-years; relative rate, 1.39; 95% CI, 1.26-1.53), and nuclear medicine (2.0 vs 0.8 per 1000 person-years; relative rate, 2.70; 95% CI, 2.20-3.30).

For example, all angiographic studies were included if they used CT, MRI, ultrasound, or nuclear medicine, and these study types were included with the specific imaging modality. This study has several strengths, including its large size, inclusion of imaging data from 7 US sites and from Ontario, inclusion of all age groups, and accurate assessment of utilization, including examinations conducted outside health care plans with reimbursement claims. Papanicolas Changes in annual growth in ultrasound were smaller among adults and children in the United States and Ontario. The Ontario portion of the study was also supported by ICES, which is funded by an annual grant from the Ontario Ministry of Health, Long-Term Care. KiK .fbN {EZa|T8UrDv5y8;u4ETGdji~cJT#$W&FHt!oLv\cR[gfH =?G MRI is an imaging technique designed to visualise internal structures of the body using magnetic and electromagnetic fields which induce a resonance effect of hydrogen atoms. R, Miglioretti Medicare imaging demonstration evaluation report to Congress. Smith-Bindman Imaging rates of CT and MRI were higher in US health care systems compared with Ontario, but these differences diminished over time. JA, Edwards Rates of CT, MRI, and ultrasound imaging increased over time in the United States and Ontario, whereas nuclear medicine imaging declined over time (Table 1). We know your life is busy, which is why our scheduling is flexible and our quick turnaround time for test results allows you to have peace of mind sooner rather than later. MRIs are a common imaging diagnostic test that doctors recommend for a range of conditions and concerns. Data are for 2019 or latest year available. Imaging rates within anatomic areas were similar to the overall results; CT, MRI, and ultrasound increased and nuclear medicine declined over time (Figure 2). Horn <> Utilization data of CT, MRI, ultrasound, and nuclear medicine were obtained from 2000 through 2016 for individuals enrolled in 7 US health care systems and individuals living in Ontario who were eligible for the Ontario Health Insurance Plan. The institutional review boards of all collaborating institutions and the University of California, Davis, Statistical Coordinating Center approved the study, and a waiver of individual consent was obtained.

SM, Hart bS[-lLA2n#@w} sac3*,}_!nz} u: v &[z8eb9K=$ v3O'@ FI J0o"zlS8=} Third, because of differences in billing practices, it was not possible to accurately estimate anatomic areas imaged with ultrasound or to make detailed comparisons between the United States and Ontario that accounted for imaging during pregnancy. DC, Parker <> The HMO Research Network virtual data warehouse: a public data model to support collaboration. et al. DL, Ron It found that although the growth in imaging slowed in the early 2000s, it ticked back up in recent years for computerized tomography (CT) and magnetic resonance imaging (MRI) in most patient age groups. This means that some people may not have their first screening mammogram until they are 52 or 53 years. To evaluate recent trends in medical imaging. Although Ontario is Canadas largest province, it may not reflect practices in other provinces or territories. DC, Parker During the scan you won't feel anything. Within these modalities, all examination types were included. CT indicates computed tomography; MRI, magnetic resonance imaging. Data sources. Magnetic Resonance Imaging (MRI) exams help physicians diagnose a range of conditions by producing images of internal organs and structures of the body. As exploratory analyses, annual imaging rates were graphed and relative imaging rates with 95% confidence intervals were calculated by imaging modality for each individual health plan, by anatomic area for CT and MRI for the United States and Ontario, and for nuclear medicine and ultrasound overall, and stratified by US plan type (integrated vs mixed-model plans) after adjusting for the annual mean Elixhauser comorbidity score22 and sex. Magnetic Resonance Imaging (MRI) Exams per 1,000 Population | Commonwealth Fund Our Scorecard ranks every state's health care system based on how well it provides high-quality, accessible, and equitable health care. HJ, Fay A common issue with MRI machines was the narrow, tunnel-like space for the patient to lie in making MRIs uncomfortable for most people and impossible for people with conditions like claustrophobia. <> CMII 2017. survey. The less frequent CT use in adults in Ontario may reflect greater awareness of issues of ionizing radiation exposure in adults. xU]k0}7?Gk`Y$mAk{(}R34qxvgK`{}9 'gz $gMpd]~*ySd{BXh2a@0qH@0 a0 @da@m" Second, the indication for imaging was not available; thus, it is not possible to determine whether imaging was appropriate or inappropriate for any given test or whether imaging utilization was associated with improved patient outcomes. Dr Miglioretti reported previous advisory board membership for Hologic. In addition, he said, this effect isn't seen equally among the various FDA-approved. endobj In this retrospective cohort study of 135 million imaging examinations conducted in 7 US integrated health care systems and in Ontario, annual growth in imaging rates among US adults and older adults slowed over time for computed tomography (CT; from an 11.6% annual percentage increase among adults and 9.5% among older adults in 2000-2006 to 3.7% among adults in 2013-2016 and 5.2% among older adults in 2014-2016) and for magnetic resonance imaging (MRI; from 11.4% in 2000-2004 in adults and 11.3% in 2000-2005 in older adults to 1.3% in 2007-2016 in adults and 2.2% in 2005-2016 in older adults). All US data are shown as solid curves; Ontario data are shown as dashed curves. Among children, annual growth for CT stabilized or declined (United States: from 10.1% in 2000-2005 to 0.8% in 2013-2016; Ontario: from 3.3% in 2000-2006 to 5.3% in 2006-2016), but patterns for MRI were similar to adults. Health care spending in the United States and other high-income countries. MRI uses a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body . Annual percentage changes with 95% confidence intervals are shown in eFigure 1 in the Supplement. Annual growth in CT, MRI, and ultrasound was highest in the earlier years (ie, between 2000 and 2006), but utilization continued to rise between 2012 and 2016 (1%-5% annually) for most age groups both in the US sites and in Ontario. They may even take them for granted. Patterns in Ontario were similar.
