Research Abstract

The cartilage tissue, non-invasive evaluation their differentiation, the degree of tissue maturation, or three-dimensional structure of calcification further fine is difficult. The motion is limited by complex extracellular matrix and cell membrane, water molecules that make up 70-80% of the mass of the articular cartilage shows the diffuse component of multiple-multidirectional. In order to understand the relationship between the material properties of the cartilage and motility in the tissue water molecules, the apparent diffusion coefficient in the diffusion-weighted MR imaging is useful. Relates perfusion behavior of the surrounding tissue that would affect the diffusion behavior, using a diffusion weighted imaging obtained from several malignant tumors, presented to study the relationship.
