Results An MRI scan usually lasts between 20 minutes to an hour, but some tests can be much longer. Usually it's very safe. One grainy, gray-scale image of a brain changed science and medicine forever. This compares to the 13 minutes or more it would take for a doctor to manually analyse the images after the MRI scan has been performed. E, Tokuoka DL, Ron There are now special MRI machines that have a bigger opening to make the imaging more accessible for everyone. Specifically, in 2016, imaging rates for CT in mixed compared with integrated plans were 392 vs 401 per 1000 person-years in older adults (relative rate, 0.98; 95% CI, 0.94-1.01) and 136 vs 124 per 1000 person-years in adults (relative rate, 1.10; 95% CI, 1.04-1.16). Quiz Ref IDUse of CT, MRI, and ultrasound in 7 US integrated health care systems and in Ontario has continued to increase in recent years. 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. $.' Nuclear medicine declined over the entire observed time period, but declines were largest after 2009 in the United States (10.5%) and after 2008 in Ontario (9.6%). 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).
