Bottom Line: It is frequently exposed to trauma, degeneration, and repetitive wear and tear.MRI has played a vital role in evaluation of articular cartilage.With the availability of advanced repair surgeries for cartilage lesions, there has been an increased demand for improved cartilage imaging techniques.

ABSTRACT
We tried to review the role of magnetic resonance imaging (MRI) in understanding microscopic and morphologic structure of the articular cartilage. The optimal protocols and available spin-echo sequences in present day practice are reviewed in context of common pathologies of articular cartilage. The future trends of articular cartilage imaging have been discussed with their appropriateness. In diarthrodial joints of the body, articular cartilage is functionally very important. It is frequently exposed to trauma, degeneration, and repetitive wear and tear. MRI has played a vital role in evaluation of articular cartilage. With the availability of advanced repair surgeries for cartilage lesions, there has been an increased demand for improved cartilage imaging techniques. Recent advances in imaging strategies for native and postoperative articular cartilage open up an entirely new approach in management of cartilage-related pathologies.

Axial T1 TSE image (600/6.6, NEX 2.0, 180° flip angle) of the retropatellar cartilage obtained in a volunteer reveals morphologically normal cartilage (A). Corresponding T2 maps for the early (B) and late unloading (C). Note no visible differences over time

Figure 19: Axial T1 TSE image (600/6.6, NEX 2.0, 180° flip angle) of the retropatellar cartilage obtained in a volunteer reveals morphologically normal cartilage (A). Corresponding T2 maps for the early (B) and late unloading (C). Note no visible differences over time

Mentions: The function of the water and collagen content of the articular cartilage matrix is determined by the T2 relaxation time. The T2 relaxation values are variable, based upon the articular cartilage thickness comparable to the distribution of the water and proteoglycans in the ECM.[49] The measured distribution of the T2 relaxation is depicted as areas of increased or decreased content of the water directly proportional to the degree of the cartilage disintegration.[50] It is of utmost importance to select the MRI technique that has high accuracy to measure T2 relaxation [Figure 19].
