The pelvic ultrasound is used to examine the organs within the female pelvis with real-time images. Organs in the pelvis that may need ultrasound scanning include the uterus, vagina, cervix, ovaries, and fallopian tubes. Doppler is also carried out along the ultrasound to show blood flow and to detect abnormalities. There are two methods to examine the pelvis: transabdominal (through the abdomen) and transvaginal (through the vagina). Your doctor will determine which type you may need depending on your circumstances. The exam takes 30 minutes.
