Endometriosis ultrasound
Endometriosis is a chronic condition in which tissue similar to the uterine lining grows outside the uterus. An expert transvaginal ultrasound can detect many of its forms without surgery.
Symptoms that warrant an ultrasound
- painful periods not relieved by painkillers
- chronic pelvic pain
- pain during intercourse, bowel movements or urination
- difficulty getting pregnant
What the scan assesses
The doctor systematically examines the pelvic organs and the areas where endometriosis most often occurs.
- ovarian endometriomas ("chocolate cysts")
- adenomyosis — endometriosis within the uterine muscle
- deep endometriosis nodules (ligaments, rectovaginal septum, bowel, bladder)
- adhesions and organ mobility
Preparation
The scan takes about 30–45 minutes. Empty your bladder before the visit; the doctor may suggest a light diet the day before. Bring previous results.

Frequently asked questions
Can ultrasound detect endometriosis?
Expert ultrasound detects endometriomas, adenomyosis and many deep nodules. Small peritoneal lesions may not be visible — a normal scan does not rule out the disease if symptoms are typical.
When is the best time for the scan?
Any day of the cycle except days of heavy bleeding.
Is it painful?
Usually not. With active endometriosis, probe pressure may cause pain at the affected sites — which is also useful diagnostic information.
