MRI's,
CT Scans and X-Rays
This article will discuss
one of the most misunderstood areas in all of spine care:
diagnostic imaging.
Diagnostic imaging refers
to tests such as x-rays, CAT scans and magnetic resonance
imaging (MRI).
Many of you
have had some or all of these tests. You may have been
told you had an abnormality. Were you also told that
such an abnormality may have NOTHING TO DO WITH YOUR
PAIN?
Studies of normal adults who
have NEVER had back or neck pain have shown that up to
40% will have abnormalities
on imaging studies (References
6,7,8). The implications
of this fact are very important. It means that these
tests are not very good at distinguishing normals from
abnormals. Furthermore, it means that if a person develops
back pain and has one of these studies, any abnormality
that shows up may have nothing to do with the pain.
There are other scientific articles in this booklet which
look
further at this issue.
Experts agree that only in
10% to 15% of the cases can a definite cause for back
pain
be found. In the rest
of the cases NO ONE KNOWS for sure. Chiropractors say
misalignment is the problem; physical therapists speak
of muscle spasm; surgeons talk herniated and degenerated
discs. All may be occasionally correct but most of
the time we simply don't know.
At this clinic, in recognition
of the above facts, we try to operate from things we
DO know. We may not know
the precise cause of your pain but we can precisely
identify your functional ability and tell you if it's
normal or
abnormal. If abnormal, we help you strive to make it
normal. As you improve your function you will likely
experience less pain regardless the cause.
The New England
Journal of Medicine is probably the most prestigious
and widely read peer-reviewed medical
journal in the world. They recently published a study
relating to medical imaging like MRI scans. To learn
