| Outline of Final Research Achievements |
MRI is used recently to assess the degeneration of articular cartilage. However articular cartilage is a thin layer and has same signal intensity as the joint fluid, so it is difficult to distinguish between the articular cartilage and the adjacent joint fluid on MR images. To depict the articular cartilage, we obtained MR images after injecting a contrast agent with manganese ion. The agent depressed the signal intensity of the joint fluid, which made a contrast between the articular cartilage and the joint fluid. This new method enabled us to visualize the articular cartilage more vividly and in the earlier stage than the conventional method.
