A pelvic ultrasound — also called a pelvic scan, gynaecology ultrasound, USG pelvis, pelvic sonogram or pelvic echography — uses high-frequency sound waves to build real-time images of the female pelvic organs. There is no radiation and no injection.
It shows the uterus, the endometrium (womb lining), the cervix, both ovaries, the adnexa and the bladder. That lets it pick up fibroids, ovarian cysts, the ovarian appearance linked to PCOS, endometrial thickening and polyps, a displaced coil, and pelvic free fluid — and it is the first-line test for pelvic pain, heavy or irregular bleeding and fertility questions.
