When To Seek Medical Imaging
Updated: 18 hours ago
Here are our best resources to help you decide whether to seek imaging for your concerns after you have been given a diagnosis as an adult. You might have had this discussion with our coaches already, whether to justify imaging (and surgery) or not, so here is the evidence for our input.
Why not seek imaging for everything? Generally, imaging is helpful only if bracing/casting, surgery, injections, or a change in medical management, such as a change in medications, is likely to be more effective than non-invasive, exercise-based management. Seeking imaging outside of this context, often to just “find the cause of pain,” often has more long-term harms than benefits for your health. As ethical health care professionals, it is within our duty of care to not encourage seeking imaging too “early” as we have clear evidence this can be harmful to you in the long term, despite the promise of reassurance (Unintended consequences: quantifying the benefits, iatrogenic harms and downstream cascade costs of musculoskeletal MRI in UK primary care + Iatrogenic Consequences of Early Magnetic Resonance Imaging in Acute, Work-Related, Disabling Low Back Pain + Incidentalomas, SPEW, and VOMIT—radiological dyspepsia? + The catastrophization effects of an MRI report on the patient and surgeon and the benefits of ‘clinical reporting’ + Does Rewording MRI Reports Improve Patient Understanding and Emotional Response to a Clinical Report?). We strongly encourage that “before you scan, have a plan” as we will always support the “wo/man not the scan.”
Be informed of the normal, healthy aging appropriate findings that can mistakenly be labelled or believed as “abnormal” (EBP Podcast Back pain fact with patient voice, Joe - 'Scans rarely show the cause of pain' + Physical Therapist Debunks 5 Most Common Myths About MRIs & X-Rays + Imaging Myths - E3 Rehab + RACGP - Towards appropriate imaging: Tips for practice + To Image or not to Image | Andrew Cuff | Ep. 052 + Gurpreet Singh - Discussing when a scan may be useful + Ben Whybrow "“So can I have an MRI?” - A frequent but difficult conversation in MSK ACR Appropriateness Criteria + Base Rates Across Common MSK Imaging Findings. What are normal but labelled mistakenly as “abnormal” imaging - Google Docs + Structure is not Destiny - please don't rush to freaking out about your x-ray, MRI or ultrasound — Greg Lehman). Also you should be informed of what “normal” symptoms recovery is for many concerns people are seeking imaging for due to expectation that “this should still be symptomatic (Talking About Natural History- The NAF Physio Podcast - Apple + Prognosis / Natural History - Google Docs).
So here is our reasoning for encouraging seeking imaging for the common areas in the body.
Body region (Click on a heading to skip to it's section):

Neck and Mid Back
Symptoms post-high sudden trauma from a car accident, fall, or sports injury, or nerve-related pain, numbness, or weakness worsening within weeks around the neck, shoulder, arm, and hand. When these symptoms occur spontaneously or gradually over days, a visit with a healthcare practitioner to confirm the need or lack of need for imaging is advised. Pain is not often the most important concerning feature.
“Pinched” Nerves- many can resolve without the need for imaging to guide management (Cervical Radiculopathy | “Pinched” Nerve in Neck Rehab (Education | Exercises | Surgery | Myths)).
Spinal cord injury
What could be normal neck-related imaging changes for your age and physical activity levels?
“Most subjects presented with disc bulging (87.6%), which significantly increased with age in terms of frequency, severity, and number of levels. Even most subjects in their 20s had bulging discs, with 73.3% and 78.0% of males and females, respectively. In contrast, few asymptomatic subjects were diagnosed with SCC (5.3%) or increased signal intensity (2.3%). These numbers increased with age, particularly after age 50 years. SCC mainly involved 1 level (58%) or 2 levels (38%), and predominantly occurred at C5-C6 (41%) and C6-C7 (27%)” (Abnormal findings on magnetic resonance images of the cervical spines in 1211 asymptomatic subjects - PubMed)

Low Back
Symptoms after a car accident, fall, or sports injury, or present with nerve-related leg pain, numbness, or weakness worsening within weeks around the hip, knee and/or ankle. Pain is not often the most important concerning feature.

Knee

Symptoms with swelling within hours after a fall or high speed knee twisting action warrant further assessment but some conditions presenting like this still might not need imaging to manage well
Suspected ACL injury- Imaging useful for some if surgery will be more helpful then no surgery:

Seeking imaging to make a choice between surgical vs non-surgical care? See these decision making aids/articles:

Can you have an ACL injury without knowing it?
It is much more common feel the need to seek care after an accidant causing an ACL injury but in some studies ligament changes can be seen without symptoms or found incidentally such as an old finding during a short term knee OA flare-up (Non-traumatic anterior cruciate ligament abnormalities and their relationship to osteoarthritis + Prevalence of abnormal findings in 230 knees of asymptomatic adults using 3.0 T MRI).

Suspected knee osteoarthritis (OA) when non-surgical management is no longer satisfactory (which is less than most think) imaging is often ordered to plan surgery. Imaging should not be used to “decide” if surgery is worth it. Your quality of life and ability to be active is more important for that decision Method Health- Knee Osteoarthritis (OA)
What could be normal knee joint-related imaging changes for your age and physical activity levels?
Suspected knee bony injury- suspected after sudden knee pain after a fall or direct impact onto knee or knee cap with obvious bony change or strong inability to walk on the suspect knee, where bracing or surgery will be helpful.
Suspected knee tendon pain - Imaging is not recommended for helping manage knee tendon pain Method Health- Tendon Pain Resolution
Hip
Symptoms after a fall, car accident warrant further assessment but some conditions presenting like this still might not need imaging to manage well

Correlation of MRI findings with clinical findings of trochanteric pain syndrome “detection of these abnormalities on MRI is a poor predictor of trochanteric pain syndrome as these findings are present in a high percentage of patients without trochanteric pain.”
Suspected hip joint/rim/”labrum” pain that is unlikely related to hip OA
What could be a normal hip rim-related imaging finding for your age and physical activity levels?
Suspected hip bony injuries - suspected, often late into development, when someone is unable to hop on one leg.
Hamstring

For a suspected hamstring strain or general muscle strains, imaging is often not encouraged for helping with muscle strain management. One reason is that your symptoms will often not match your medical imaging Method Health- Muscle Strains and Exercise.
Seek advice for children still growing with suspected "muscle strains."
Shoulder

Shoulder pain not originating from a large energy event like a sports tackle or fall will often not benefit from seeking imaging immediatly Method Health- The Grumpy Shoulder

Calf/Achilles

Suspected Achilles full injury also called a ”rupture”- Imaging is helpful if you're planning surgical management.
Physio Edge podcast- Achilles tendon ruptures: Rehab & recovery with Prof. Peter Malliaras + Tendon Rehabilitation - YouTube- You do not need imaging to confirm an Achilles tendon rupture or justify being placed immediately in a medical boot. Clinical tests are fine. However, there is some nuance to the rupture's location and to whether surgery (and the need for pre-surgery imaging) will be helpful for your future goals. Conversely, ultrasound or MRI measures of tendon elongation may not be effective in predicting satisfaction with recovery.

Wrist/Fingers

Imaging is helpful when wrist or finger bone injuries are likely after a fall onto your hands or sudden push or pull from your fingers that leaves you with swelling, weakness and tenderness to touch over a bone to help dedice if bracing or surgery will be helpful immediatly Hand - University Hospitals Coventry & Warwickshire + The UHCW Hand Centre - hand injuries
