Percentage of imaging tests ordered by orthopedic surgeons out of fear of being sued, rather than out of necessity. Defensive imaging accounted for 11% of X-rays, 38% of MRIs, 33% of CT scans, 57% of bone scans and 53% of ultrasounds. Defensive medicine also accounted for 35% of costs, nearly all of it from MRIs.
