Synopsis

Keywords: Uterus, Cancer, Amide proton transfer-weighted imaging; T2 mapping ; endometrioid adenocarcinoma; risk stratification

Motivation: Preoperative risk stratification of endometrioid adenocarcinoma (EA) impacts the choice of operative modality and prognosis of patients.

Goal(s): We aimed to perform an accurate and non-invasive preoperative risk stratification method for EA by MRI sequences.

Approach: APTw imaging as well as T2 mapping were included in this study.

Results: The APTw and T2 values showed significant differences between the low- and non-low-risk groups. Combining APTw with T2 mapping achieved the highest diagnostic efficacy in the preoperative risk stratification.

Impact: This suggested that the integrated use of APTw and T2 mapping can be an effective method for the preoperative risk assessment of EA.
