Pelvic MRI protocol: endometrial carcinoma
A dedicated MRI protocol is crucial for accurate MRI evaluation of endometrial carcinomas.
Imaging is optimally performed after 3 hours of fasting to reduce bowel peristalsis and following administration of an antiperistaltic agent unless contraindicated.
Supine position using a pelvic phased-array multi-coil .
- high resolution T2 weighted imaging in 3 orthogonal planes angled to the uterine cavity with further sequences angled to the cervix if cervical involvement is suspected
- slice thickness <4 mm
- FOV 25 cm
- high resolution matrix
- T1 weighted imaging of retroperitoneum to detect nodal involvement
- axial or coronal
- extended field of view (FOV)
- dynamic gadolinium-enhanced T1-weighted imaging (small field of view): usually 2 planes (sagittal and axial oblique) or 3 planes to evaluate the extent of myometrial and cervical involvement
- optimal timing to detect myometrial invasion is approximately 2 minutes following contrast injection
