Purpose
To review current MRI techniques for knee imaging and to describe the spectrum of knee pathologies that can be identified through MRI.
Methods
A comprehensive review of MRI sequences used in knee evaluation, including T1, T2, proton-density, and fat-suppressed techniques. Various disease entities involving ligaments, menisci, cartilage, synovium, and bone were discussed with associated imaging features.
Key Findings
- MRI is highly effective for diagnosing a wide range of intra-articular and periarticular knee conditions.
- Advances in MRI technology have improved the sensitivity and specificity for evaluating meniscal tears, ligamentous injuries, cartilage damage, and synovial disorders.
- Accurate interpretation requires understanding of both imaging technique and knee anatomy.
Conclusion
MRI is the modality of choice for noninvasive evaluation of internal knee derangements and should be tailored to the clinical question and patient-specific considerations.
What This Means for Patients
MRI allows for accurate diagnosis of knee injuries and conditions without surgery or radiation. It helps guide treatment plans for pain, instability, and mechanical symptoms of the knee.
