Pelvic protocol for endometriosis (MRI)

Evaluation of known endometriosis with MRI requires a slightly different protocol to a routine pelvic MRI (see Pelvic MRI protocol: routine), and should probably be reserved for known cases of endometriosis rather than for the assessment of pelvic pain. IV (or IM) Buscopan® is administered to r...
