Researchers looked at 2,000 requests for lower back and head MRIs in Canada and found that more than half of the lower-back scan requests were either inappropriate or of uncertain value for the patient. Eighty-three percent of the head scans were deemed appropriate. The findings, published online in JAMA Internal Medicine, suggests the need for more dialogue about diagnostic imaging and its implications, said Johns Hopkins Medicine's Dr. Frederick Korley, who was not involved in the study.
