Mapping the Physiological Parameters of Articular Cartilage with Magnetic Resonance Imaging

The ability of magnetic resonance imaging (MRI) to visualize the spatial distribution of parameters related to the physiological and structural properties of tissues makes it an ideal tool for the study of articular cartilage. A variety of ingenious MRI methods have been devised to probe the complex composition and biochemistry of normal and degenerate articular cartilage. In this article we review the current status of this research and pose some questions concerning the future directions of articular cartilage research and clinical applications.
