Evaluation of rADC values in characteristic lesions in MSA, PSP, and PD by placing ROIs using 3-T systems can provide useful additional information for differentiating these disorders.

We demonstrated 2 cases of uterine endometrial stromal sarcoma with emphasis on diffusion-weighted imaging. The tumors showed high signal intensity, and their tumor venous thrombi were clearly depicted on diffusion-weighted imaging. Diffusion-weighted imaging is a useful method not only for diagnosis of endometrial stromal sarcoma but also for preoperative planning.
