MRI findings in athletic groin pain: correlation of imaging with history and examination
The upshot
In athletes with groin pain, can an MRI scan alone tell you what is wrong?
In athletes, MRI shows many abnormal findings even in people without any groin pain, and these imaging findings line up only weakly with symptoms and examination. A scan on its own is not enough to make the diagnosis, and the clinical picture must guide interpretation.

Key points
- MRI abnormalities of the groin are common in both symptomatic and asymptomatic athletes, so an abnormal scan does not automatically explain the pain.
- Specific imaging findings correlated only weakly or inconsistently with the athlete's history and physical examination.
- Imaging alone is insufficient for diagnosis, and findings must be interpreted alongside the clinical presentation.
- Because abnormalities appear in pain-free athletes, MRI carries a real risk of false-positive over-diagnosis.
How it was conducted
- Design
- Comparative correlation study of imaging versus clinical findings
- Participants
- Athletes with symptomatic groin pain compared with asymptomatic athletes
- Assessment
- MRI of the groin plus clinical history and physical examination
- Main comparison
- Whether MRI findings matched symptoms and examination across the two groups
What they found
- Multiple MRI findings were present in both the symptomatic and the asymptomatic groups.
- The correlation between specific imaging findings and the clinical presentation was weak or inconsistent.
Limitations
- The available text reports only qualitative conclusions and gives no sample sizes, effect sizes, or statistical measures, so the strength of the associations cannot be judged.
- Without stated diagnostic accuracy figures, it is not possible to quantify how often MRI was misleading.
- The grouping into symptomatic versus asymptomatic athletes is described only in general terms, limiting how far the results can be generalised.
Why it matters
- For patients
- If you are an athlete with groin pain, an abnormal MRI may not be the cause of your symptoms, so the scan should be interpreted together with your history and examination, not on its own.
- For clinicians
- Interpret groin MRI in athletes with caution, because abnormalities are common in pain-free athletes and correlate poorly with symptoms; anchor the diagnosis in the clinical assessment.
- For readers
- This study is a reminder that imaging findings and symptoms often do not match, and that a scan alone rarely settles a diagnosis.
