Gynecologic ultrasound.

For most women, pelvic sonography using a transvaginal probe is the imaging modality of choice for evaluating the uterus and adnexae. It is reliable for detecting ovarian cysts and other adnexal masses, and it can often determine if a lesion can be observed on serial examinations or if it requires more urgent attention. Uterine ultrasound is reliable for evaluating both the normal and abnormal endometrium and myometrium. In cases that are technically limited, or in those that are difficult to interpret, a tailored MR imaging examination often can be helpful.
