In this test, saline is injected in to the uterus while performing vaginal ultrasound to make sure that there are no uterine abnormalities
(
fibroids,
polyps,
scar tissue or
uterine malformations) which may interfere with embryo implantation. The top left picture demonstrates a normal test. The dark area, outlined in yellow, is the saline filling the uterine cavity and no abnormalities are seen. The top right ultrasound image demonstrates an abnormal uterine cavity with an irregular border caused by an endometrial polyp (outlined in red and marked by white arrow). The test takes only a few minutes to complete and is associated with little discomfort, if any. |
