Which imaging study is used to visualize the soft tissue structures within the knee joint, such as the menisci?

• A. Knee arthrography
• B. Knee ultrasound
• C. Knee CT
• D. Knee radiography

Answer: (D)

Soft tissue visualization inside the knee, like the menisci, relies on imaging that offers high contrast between different soft tissues. Magnetic resonance imaging provides superb detail of cartilage, ligaments, menisci, and surrounding fluid without radiation, making it the modality of choice for assessing intra-articular soft-tissue injuries such as meniscal tears. Radiographs and CT are excellent for bone details and alignment but have limited ability to distinguish soft tissues like cartilage and menisci. Ultrasound can evaluate some superficial soft tissues and effusion, but it cannot reliably image the deep structures inside the joint. Knee arthrography, where contrast is injected into the joint to outline intra-articular structures on X-ray or CT, can improve visualization of certain soft-tissue components, but it is invasive and far less commonly used today than MRI. So, in evaluating soft tissue structures within the knee joint, MRI is the best choice. Among the listed options, arthrography is the closest alternative if MRI isn’t available, but MRI remains the standard.
