Radiology · Gynaecological imaging: MRI staging of endometrial cancer

Sample item

A woman with biopsy-proven endometrial carcinoma needs preoperative imaging. Which MRI finding determines the stage and the need for lymph node assessment?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Depth of myometrial invasion, assessed on contrast-enhanced and diffusion images

The depth of myometrial invasion, particularly whether it exceeds half the myometrial thickness, determines the stage and risk group, and MRI also shows cervical stromal invasion. Dynamic contrast enhancement improves accuracy.

Option by option

  • A. Uterine size alone

    Uterine size does not determine stage.

  • B. Presence of fibroids

    Fibroids are common and unrelated to staging.

  • C. Ovarian follicle count

    Follicle count has no role.

  • D. Depth of myometrial invasion, assessed on contrast-enhanced and diffusion images (correct)

    Correct. Myometrial invasion depth is the key staging criterion on MRI.
