Our purpose was to evaluate the role of diffusion-weighted imaging (DWI) in the diagnosis of various common pathologies of the uterine cavity, by comparing them with contrast-enhanced MRI findings. One hundred sixty-four patients with lesions in endometrial cavity were included in the study. The patients were grouped in four (one malignant and three benign groups). We have observed that the differences of the apparent diffusion coefficient, b1000q, and Cq values between various common benign and malignant lesions were statistically significant (P<.001). However, the differences of the values between benign groups were not statistically significant (P>.05). Alternatively, endometrial polyp group's signal intensity on DWI was different than the other groups.
