Overview
Pelvic MRI may be diagnostic of endometrial cancer.
567==Pelvic MRI== A dedicated pelvic MRI protocol is recommended for optimal assessment.[1] MRI is considered superior to CT for local staging. Contrast enhanced MRI imaging improves accuracy in detecting myometrial invasion.
- T1: hypo- to isointense to normal endometrium
- T1 C+(Gd): carcinomatous tissue will enhance less than normal endometrium
- T2: hyperintense or heterogeneous relative to normal endometrium
MR Imaging findings according to FIGO stage
| Stage of endometrial cancer | MRI findings |
|---|---|
|
Stage 1: tumour confined to uterus |
|
|
Stage 2: tumour extends to cervix |
|
|
Stage 3: tumour extension beyond the uterus |
|
|
Stage 4: bladder/rectal or distant metastasis |
|
