text_A: Medical societies issue guidelines for when physicians should use MRI on patients and recommend against overuse. MRI can detect health problems or confirm a diagnosis, but medical societies often recommend that MRI not be the first procedure for creating a plan to diagnose or manage a patient's complaint. A common case is to use MRI to seek a cause of low back pain; the American College of Physicians, for example, recommends against this procedure as it usually results in a negative outcome for the patient.
text_B: If your doctor suggests that you get an MRI to try to diagnose your low back pain, is this going against the advice of the American College of Physicians?
YES.
