Don't Get Hung Up on Imaging

In school, many students are taught about the clinical significance of imaging, but how many end up utilizing it clinically? It seems like I rarely go a day when I don't hear a patient or clinician mention how bad the patients' MRI findings are and how that is the reason for the patient's symptoms. "So and so blew out a disc lifting a heavy box," "I have 3 slipped discs in my neck," or "the MRI revealed impingement at C4." The list goes on and on; however, my personal favorite is "my knees are bone on bone!" Sure the MRI can pick these things up, but do they matter? While I support the use of imaging to help rule out various non-musculoskeletal pathologies and life-threatening symptoms, there is quite a bit of evidence that says we should not rely on imaging for things like determining the significance of herniate discs, stenosis, bone spurs, and more (Boden et al, 1990 & Jensen et al, 1994). What these studies reveal is that quite a few people without any symptoms or complaints have the same MRI findings as those with pain. What does this mean? While it is theoretically possible that findings like stenosis, bone spurs, and discs can create various symptoms, just because we see something on an MRI does not mean that it is the source of our patient's symptoms. This is why I get frustrated when I hear patients (or PT's) start to list off their findings or when patients and health care practitioners are pushing for surgery. As clinicians, we should regularly educate our patients on just how insignificant some imaging results can be in regard to orthopaedic complaints.

What we have discussed thus far does not even touch upon our understanding of modern pain science. Having recently completed Butler and Moseley's Explain Pain, my understanding of what "pain" actually means and how it develops has changed drastically. We don't actually have pain receptors. We have an intricate system of "danger" (noci-) receptors. This system is influenced by different cultural upbringings, our surroundings, and much more. It can even adapt to affect and be affect by other parts of the nervous system! What we feels as pain often occurs for a reason, to warn us. However, the nervous system can become hypersensitive and lead to various types of chronic pain. Think about diagnoses such as Chronic Regional Pain Syndrome. These patients actually visualize the affected body part as being enlarged! How is it that someone with horrendous pain from a "blown disc" can immediately get near 100% within a couple days with something like repeated motions? We aren't pushing the disc back into place; we are affecting the nervous system! This ties right back in with abnormal imaging findings. We cannot let the results of an MRI impact our clinical decisions and treatments based on this. I am not advocating against the use of MRI's (or other types) in general, but I believe we do a disservice to our patients by biasing their mind with MRI results before even giving therapy a shot. This thought process alone can affect how the patient perceives their disability and affects the function of the nervous system. With the right treatment technique (repeated motions, manual therapy, chronic pain education), most patients should see improvement.

I agree completely. Treating solely the MRI will set you on the wrong path However, knowledge of how to read MRIs and compare them with the clinical presentation is invaluable and should not be overlooked.
With our continuing fight to extend direct access to Physical Therapy we can not overlook this powerful diagnostic tool and add it to our information gained by the clinical examination.
MRI and clinical exam along with the history can help us paint a complete picture. This blog is completely correct. We can not simply treat the MRI, however more than likely the patient has pain in the area that is being imaged so they will not be asymptomatic. There is no way to be certain of the exact pain generator - even surgery does not have a perfect track record of identifying it. All we can do is increase our liklihoods and this is done by using every piece of diagnostics that we have, from MRI to clinical presentation.
For PT student I recommend not taking your studying of imaging lightly. The ability to interpret an MRI or "x-ray" is important in your communication with radiologists and physicians and to formulate your own opinion. The information gathered in an MRI can only add to your knowledge of the patient's symptoms. Just make sure the correlate to what you are finding clinically.
In the end our treatment is our guide. If treatment is successful then we are on the right path. Checking your patients symptom levels before and after treatment is a piece that shouldn't be overlooked.

Hope this added to the conversation.
