Kegunaan isotop disprosium
- 165Dy (with a half-life of 140 min) is commonly used in arthritis therapy (radiosynovectomy). Rheumatic inflammation of the membranes of joints is often treated by the injection of 165Dy-ferric oxide directly into the joint space of the knee. Leakage from the joint has been shown to be minimal.
