Ultrasound or MRI first line for endometriosis diagnosis: new guidelines

Doctors can diagnose endometriosis with transvaginal ultrasound or MRI and start hormonal treatments to manage symptoms while diagnostic investigations are underway, updated guidelines say.
RANZCOG’s practice guideline update, the first since 2021, emphasises non-invasive diagnosis and early treatment.
“A pelvic MRI can be offered if ultrasound is not available or if deep endometriosis is suspected,” the new guidelines say.
“If transvaginal ultrasound is not possible or not appropriate, due to age or sexual history, and MRI is not available, a transabdominal ultrasound could be suggested.
