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 helpful, influential MRI studies is so small? False positive MRI results upset those who get these results. They inspire fear or caution where it’s not always needed. MRIs like this confuse the proper treatment plan. They cost quite a bit. Spengel Chiropractic carefully evaluates the necessity of MRI in the McHenry chiropractic treatment plan of McHenry 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 proper. Of those, only 13% uncovered anything that needed to be addressed. 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 misinform. 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 Spengel Chiropractic, to correlate all such findings with patient symptoms. (1,3) Your McHenry chiropractor does this!

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 (except when “red flags” are present– issues that indicate something more sinister). (4) A review of the effectiveness of the Canadian Choosing Wisely recommendations for imaging nonspecific spinal pain and symptoms stated that there is very low risk of missing a serious cause of back pain. (5) The objective of guidelines is less imaging, fewer false positives.  Spengel Chiropractic wants what’s best for our McHenry chiropractic care patients.

COX® TECHNIC’S VIEW

Chiropractors like yours at Spengel Chiropractic study all the symptoms, tests and images our McHenry chiropractic back pain patients [[present on|bring with them39] their first McHenry chiropractic visit. So many back pain patients come to Spengel Chiropractic with MRI images already in-hand. Spengel Chiropractic will look at them but will depend more on clinical exam findings and correlate them to what the MRI reveals. A rule of thumb with the Cox Technic System of Back Pain Relief is to seek 50% decrease of back pain in the first 30 days of care before arranging more imaging or testing or referring for surgical consultation.
