Tests – what are they good for?
When it comes to back pain tests, of
MRIs that question must be examined. What are MRIs good
for when the percentage
of helpful, influential MRI studies is so minor?
False positive MRI results distress those who receive
these results. They arouse fear or caution where it
is not always needed. MRIs like this blur the
proper treatment plan. They spend a lot of money.
Yorkville Chiropractic and Wellness Centre carefully evaluates the need for
MRI in the Toronto chiropractic treatment plan of Toronto
back pain relief.
MRI interpretations by
radiologists often differ.
The true-positive finding rate was 56.4%, and the miss-rate was 43.6%. (1)
MRI imaging may trigger false suspicion. When
following the guidelines of the American College of Radiology, 93% of lumbar
spine MRIs were proper. Of those, only 13% revealed
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 shows that the presence 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 Yorkville Chiropractic and Wellness Centre, to correlate all such
findings to patient symptoms. (1,3) Your Toronto
chiropractor does this!
Choosing Wisely guidelines for American chiropractors suggest30
not repeating spinal imaging and not obtaining 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 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 objective
of guidelines is less imaging, fewer false positives. Yorkville Chiropractic and Wellness Centre wants what is
best for our Toronto chiropractic care patients.

A rule of thumb with the Cox Technic System of Back Pain Relief is to work
toward 50% decrease of back pain in the first 30 days
of care before arranging more imaging or
testing or referring for surgical consultation. (6)
