Which imaging modality is considered the most accurate for preoperative assessment of the depth of myometrial invasion and cervical stromal involvement in endometrial carcinoma?

• A Transvaginal ultrasound with colour Doppler
• B FDG positron emission tomography
• C Computed tomography of abdomen and pelvis
• D Contrast-enhanced magnetic resonance imaging ✓

Explanation

Contrast-enhanced dynamic MRI is the modality of choice for local staging: interruption or disruption of the normal enhancing junctional zone indicates myometrial invasion, and loss of the low signal cervical stromal ring suggests cervical stromal invasion. Ultrasound detects endometrial thickening but quantifies invasion poorly. CT and PET assess nodal and distant disease rather than depth of local invasion.
