Magnetic resonance arthrography. A) Coronal T1 fat-saturat- ed magnetic resonance image post intra-articular contrast injection in an 18-year-old female with lateral meniscus linear signal that is intermedi- ate in signal intensity (white arrow), compared to bright contrast injected into joint space (open arrow), probably representing granulation tissue in a previously surgically repaired lateral meniscus. B) Coronal T1 fat-satu- rated magnetic resonance image post intra-articular contrast injection in a 19-year-old male demonstrating a contrast-bright intensity defect (black arrow) in the medial meniscus, representing a radial tear
