Diagnosis
Can imaging tests diagnose endometriosis or adenomyosis?
The short answer
Yes, MRI and high-resolution transvaginal ultrasound can help identify endometriosis or adenomyosis and guide treatment planning. A normal scan doesn’t rule out either condition, as smaller lesions and superficial endometriosis can be missed.
Yes, imaging can help, especially when it shows findings such as adenomyosis in the uterine muscle, ovarian endometriomas, or deep infiltrating endometriosis. MRI and high-resolution transvaginal ultrasound are the most commonly used tools. When they’re positive, they can clarify the diagnosis and help us plan treatment and surgical strategy.
A normal scan, though, doesn’t rule out endometriosis or adenomyosis. Smaller lesions and superficial endometriosis can be missed, so we interpret imaging alongside your symptoms and a thorough evaluation. If your test results conflict with how you feel, our team can help you make sense of the full picture and discuss next steps.

Questions people ask next
All diagnosis questionsShould I trust normal imaging if symptoms persist?
A normal ultrasound or MRI can be reassuring, but it doesn’t automatically explain away ongoing symptoms. Endometriosis, and sometimes adenomyosis, can still be present, so your symptom history remains the primary guide when symptoms persist.
Can adenomyosis be seen on ultrasound?
Yes, adenomyosis can often be suspected on transvaginal ultrasound, especially when interpreted by experienced clinicians. Ultrasound can show uterine muscle changes, not gland tissue directly, but adenomyosis can be missed; MRI can help when the diagnosis is uncertain.
When is imaging most helpful for endometriosis?
Imaging is most helpful when clarifying what may be driving your symptoms before treatment, or when we suspect deeper disease that may involve the bowel or bladder. It can help guide surgical planning, but it can’t rule out endometriosis.
How are endometriomas diagnosed—do I need MRI or surgery?
Most endometriomas can be diagnosed with a high-quality transvaginal ultrasound. In many cases, surgery isn't needed to confirm it; MRI is typically used when ultrasound is unclear, to distinguish an endometrioma from other cysts, or to map possible deep endometriosis before surgery.
