Standard MRI of the female pelvis at our institution includes coronal single-shot fast spin-echo (FSE), axial T2-weighted (T2W) FSE, axial in-phase and opposed-phase T1-weighted (T1W) gradient-recalled echo (GRE), and sagittal T2W FSE fat-suppressed sequences utilizing a dedicated pelvic phased-array coil (see Table 3 ).
Fat-suppressed axial 3-dimensional T1W GRE dynamic imaging following intravenous administration of 20 mL of gadolinium contrast is obtained routinely. Delayed fat-suppressed 2-dimensional (2D) GRE imaging is subsequently obtained in another plane. If artifact from the bowel is perceived as problematic on initial sequences, glucagon may be administered by intramuscular (0.8 mg) or intravenous injection (0.2 mg). This is not routinely used in the author´s institution, however. For pelvic floor imaging, dynamic 2D GRE imaging may be performed with and without the Valsalva maneuver, as discussed later, to detect pelvic prolapse.
