MRIs - The Positives and the False Positives
Tests – what are they good for?
In the realm of back pain tests, of MRIs that question must be examined. What are MRIs good for when the percentage of constructive, influential MRI studies is so small? False positive MRI results upset those who receive such results. They arouse fear or caution where it’s not always needed. MRIs like this confuse the proper treatment plan. They cost quite a bit. Lombardy Chiropractic Clinic carefully weighs the necessity of MRI in the Augusta chiropractic treatment plan of Augusta back pain relief.
MEDICINE’S VIEW
MRI interpretations by radiologists often vary. The true-positive finding rate was 56.4%, and the miss-rate was 43.6%. (1) MRI imaging may cause false suspicion. When following the guidelines of the American College of Radiology, 93% of lumbar spine MRIs were proper. Of those, only 13% uncovered anything suspicious. Of the 36 MRIs that raised suspicion of cancer or infection, 81% were false-positive. 59% of the follow-up MRIs on those suspicious findings were false positives. (2) MRI imaging may misinform. For example, MRI shows that the presence of disc degeneration in asymptomatic persons – persons with no back pain – grows with age: 37% in 20 year olds and 96% in 80 year olds; disc bulges: 30% to 84%; disc protrusion: 29% to 43%; annular fissures 19% to 29%. These imaging findings suggest that these are signs of normal aging. They remind all doctors, remind chiropractors like yours at Lombardy Chiropractic Clinic, to compare all such findings with patient symptoms. (1,3) Your Augusta chiropractor does this!
CHIROPRACTIC’S VIEW
Choosing Wisely guidelines for American chiropractors recommend not repeating spinal imaging and not obtaining spinal imaging for patients with acute low back pain in the first 6 weeks of back pain (unless there are “red flags” – issues that indicate something more disturbing). (4) A review of the success of the Canadian Choosing Wisely recommendations for imaging nonspecific spinal pain and symptoms stated that there is very low risk of missing a worrying cause of back pain. (5) The purpose of guidelines is less imaging, fewer false positives. Lombardy Chiropractic Clinic wants what is best for our Augusta chiropractic care patients.
