Many imaging modalities are currently used to evaluate articular cartilage. Despite the fact that conventional radiography allows only indirect assessment of cartilage, it remains the primary modality for cartilage evaluation in acute and chronic articular disorders. Compared with newer modalities, arthrography has a very limited role in cartilage evaluation. Computed tomography performed after intraarticular injection of contrast material (CT arthro-tomography) is an excellent method for evaluating complex articular anatomy and pathology. More recently, due to its superior soft tissue contrast and multiplanar capability, MRI has made a significant impact in the imaging of the musculoskeletal system. The role of MRI in the assessment of articular cartilage is developing, but it is clear that MRI at present is the best noninvasive method for evaluating articular cartilage. With further technologic improvement, the role of MR in evaluating chondral abnormalities should become larger and better defined.
