Value of diffusion-weighted imaging in endometrial carcinoma staging and myometrial mesenchymal tumour characterisation.

Diffusion-weighted imaging (DWI) is an advanced technique that plays a key role in the evaluation of uterine tumours. This pictorial review explores key aspects of DWI acquisition and application, emphasising its role in diagnosing endometrial cancer and in identifying prognostic factors that influence staging as well as clinical and surgical patient management. It specifically highlights the new 2023 FIGO classification. Additionally, it examines the use of diffusion in the characterisation of myometrial mesenchymal lesions, applying the acronym BET1T2ER as a memory aid to distinguish between benign and malignant lesions. It draws particular attention to findings that could lead to misinterpretations.
