Meniscal tears are best characterized by which imaging modality?

• A. X-ray
• B. CT
• C. Ultrasound
• D. MRI

Answer: (D)

The question is testing which imaging method most accurately visualizes soft-tissue structures in the knee, specifically the menisci. MRI provides superior soft-tissue contrast, making it much more sensitive than other modalities for detecting tears in the meniscal cartilage, including subtle or complex patterns and degenerative changes. It can show whether a tear reaches the joint surface and where it is located (for example, near the red-red or red-white zones), which helps with diagnosis and planning. X-ray mainly shows bone and alignment and does not reveal meniscal pathology. CT is excellent for bone detail but has limited sensitivity for soft tissues like the menisci. Ultrasound is operator-dependent and generally not reliable for intraknee structures such as the menisci. Thus, MRI is the best choice for characterizing meniscal tears.
