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 proportion of constructive, influential MRI studies is so small? False positive MRI results trouble those who get these results. They inspire fear or caution where it is not always warranted. MRIs like this blur the proper treatment plan. They cost quite a bit. Poulin Chiropractic of Herndon and Ashburn carefully evaluates the need for MRI in the Ashburn chiropractic treatment plan of Ashburn back pain relief.

MEDICINE’S VIEW

Interpretations of MRI images by radiologists often vary.  The true-positive finding rate was 56.4%, and the miss-rate was 43.6%. (1) MRI imaging may cause misleading suspicion. When following the guidelines of the American College of Radiology, 93% of lumbar spine MRIs were appropriate. Of those, only 13% revealed anything suspicious. Of the 36 MRIs that provoked 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 mislead. For example, MRI demonstrates that the appearance of disc degeneration in asymptomatic persons – persons with no back pain – rises 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 indicate that these are signs of normal aging. They remind all doctors, remind chiropractors like yours at Poulin Chiropractic of Herndon and Ashburn, to correlate all such findings with patient symptoms.

CHIROPRACTIC’S VIEW

Choosing Wisely guidelines for American chiropractors recommend not repeating spinal imaging and not getting spinal imaging for patients with acute low back pain in the first 6 weeks of back pain (unless there are “red flags” – issues that suggest something more worrisome). (4) A review of the effectiveness of the Canadian Choosing Wisely recommendations for imaging nonspecific spinal pain and symptoms reported that there is very low risk of missing a worrying cause of back pain. (5) The goal of guidelines is less imaging, fewer false positives.  Poulin Chiropractic of Herndon and Ashburn wants what is best for our Ashburn chiropractic care patients.
