What is the name of the radiographic exam that demonstrates the degree of patency of the fallopian tubes?

The correct answer is Hysterosalpingiogram, which specifically refers to a radiographic procedure used to assess the patency of the fallopian tubes. In this examination, a contrast medium is injected into the uterine cavity, and X-ray images are taken to visualize the flow of the contrast through the fallopian tubes. This allows clinicians to determine if the tubes are open (patent) or blocked, which is crucial in evaluating female infertility.

Other options serve different purposes. A pelvic ultrasound is non-invasive and provides images of the organs in the pelvic region but does not specifically assess fallopian tube patency. Laparoscopy involves a surgical procedure where a camera is inserted into the abdomen, allowing direct visualization of the pelvic organs but is not a radiographic exam. Sonohysterography involves the use of saline solution to enhance ultrasound images of the uterine cavity, primarily used for assessing uterine abnormalities, rather than evaluating the fallopian tubes themselves.
