A gynecologic ultrasound is a non-invasive in-office procedure that is either done transabdominally or transvaginally. A gynecologic ultrasound uses sound waves to make a picture of organs and structures in the pelvis. A pelvic ultrasound looks at a woman’s ovaries, uterus, cervix, and the fallopian tubes. In many cases, your healthcare practitioner uses a pelvic ultrasound to evaluate of pelvic pain, abnormal vaginal bleeding, and uterine fibroids, and to look at the shape and size of the uterus. Pelvic ultrasound takes approximately thirty minutes.
