Abstract
OBJECTIVE. The purposes of this study were to determine the feasibility of diffusion-weighted imaging (DWI) with a single-shot echo-planar sequence and parallel technique for depicting endometrial cancer and to examine the role of this technique in preoperative assessment.SUBJECTS AND METHODS. A total of 31 patients were recruited for MRI evaluation of suspicious endometrial lesions found on transvaginal sonography. Twenty-four of the patients were proved to have endometrial cancer (patient group), and seven to have benign diseases (control group). The MRI examinations included diffusion-weighted single-shot echoplanar sequences and contrast-enhanced T1-weighted 3D fat-suppressed spoiled gradient-echo sequences. The apparent diffusion coefficient of endometrial cancer in the patient group and of normal endometrium in the control group were measured on the apparent diffusion coefficient map of each diffusion-weighted image and compared for the two groups. In the patient group, myometrial invasion was evalu...Keywords
