I spend a considerable amount of time explaining the research based imaging guidelines to my patients and that advanced imaging such as MRI is grossly overutilized. 
The Choosing Wisely campaign was launched by the American Board of Internal Medicine Foundation about three years ago. It initially had only 9 medical societies involved and in three years that number has risen to 70 medical societies.
Notice on their list of overused tests that about 3/4 are advanced imaging tests. These tests have a very high rate of false positive findings leading to much dangerous and costly further testing and treatments, not to mention anxiety for many patients.
Anyone had any recent experience with advanced imaging testing?

Do you really need that MRI?
