Purpose
To review current MRI techniques for knee imaging and describe the broad spectrum of knee pathologies detectable by MRI.
Methods
Comprehensive review of MRI sequences (T1, T2, proton density, fat suppression) and their applications in diagnosing ligament, meniscus, cartilage, synovium, and bone conditions.
Key Findings
- MRI provides high sensitivity and specificity for various intra- and periarticular knee injuries.
- Advances in MRI improve detection of subtle meniscal, ligamentous, and cartilage abnormalities.
- Accurate interpretation requires detailed knowledge of imaging physics and knee anatomy.
Conclusion
MRI is the imaging modality of choice for noninvasive evaluation of internal knee derangements and should be selected based on clinical indications.
What Does This Mean for Providers?
Use MRI tailored to clinical questions for accurate diagnosis of knee pathology. Familiarity with MRI techniques enhances interpretation and guides appropriate management strategies.
