X-ray of the uterus and fallopian tubes after the injection of a radiopaque substance is called:

A) hysterosalpingography.
B) laparoscopy.
C) culdoscopy.
D) mammography.

Hysterosalpingography specifically refers to the X-ray imaging of the uterus and fallopian tubes after the injection of a contrast material. Laparoscopy is a different diagnostic procedure that involves the insertion of a camera through a small incision in the abdomen to visualize the pelvic organs. Culdoscopy involves the insertion of a scope through the vaginal wall to visualize the ovaries and fallopian tubes. Mammography is a diagnostic test for breast cancer and does not involve imaging of the reproductive organs.
