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 2D FS PD TSE images obtained at a 3T (A) and 1.5T (B) respectively. Note the excellent contrast differentiation among cartilage surfaces, synovial fluid, and subchondral bone, as well as variation of signal intensity within the cartilage. It is very obvious that high field 3T magnet (a) depicts the finer details of the articular cartilage to a greater extent as opposed to a magnet of lesser strength. If all parameters remain similar, the voxel size in a 1.5 T remains 276% larger than in 3

Mentions: SNR is directly proportional to magnetic field strength [Figure 20]. A greater spatial resolution with equal imaging time and SNR is obtained with higher magnetic strengths.[58]
