The objective of this retrospective study is to evaluate the differences of the accuracy in endometrial adenocarcinoma using FOCUS DWI compared to that using conventional SS-EPI DWI. We calculated the accuracy by the interpretation of magnetic resonance (MR) imaging and the pathology. The accuracy in the FOCUS DWI was significantly better than that in the SS-EPI DWI. This may be due to the decrease of distortion in DWI, which induced the artifacts. There was improvement of the accuracy using the FOCUS DWI in the patient who had suspected endometrial adenocarcinoma.
