Recently a CBS News report http://www.cbsnews.com * noted “Among the reasons these tests are not recommended is that they can often find some abnormality, which although benign, could lead to further unnecessary tests and treatment….” "In 1 to 3 percent of people you will find something on the MRI, whether it be a tumor or blood vessel malformation. You don't want to find something you weren't looking for. It can be anxiety provoking…"
"The number-one reason physicians give is patient reassurance. It's harder to talk a patient out of it than to just get the scan…"In addition, doctors order scans out of fear they might miss a serious condition and be sued for misdiagnosis…”
The other side of the story…
“Though this study shows levels of imaging that are undoubtedly excessive and costs that almost certainly exceed the benefits, it does not measure or discuss the benefits of brain imaging in patients with headache..," These benefits include finding a brain tumor, stroke, brain abscess and bleeding into the brain…”” Reassuring worried patients that they do not have a serious or life-threatening condition is important…” “In addition, scans reduce the doctor's concern that they might have missed a serious condition, as well as concerns about the liability that may arise from a failure to diagnose.”
It is always a good idea to talk to your primary care practitioner, the clinician who knows you best, about the pros and cons of imaging tests.
