Uterine endometrial cancer is the most common gynecological malignancy. The development of MR scanner with high field strength resulted in improvement in diffusion-weighted (DW) imaging. Apparent diffusion coefficient value of the tissue which is derived from DW imaging has been known to characterize malignant or benign lesions. The goal of this study is to evaluate the feasibility of DW imaging at 3T MRI for uterine endometrial cancer. The results of our study suggest that DW imaging of uterine endometrial lesions is feasible in differentiating endometrial cancer from normal endometrium and endometrial benign lesions such as endometrial hyperplasia and polyps.
