It is a specialised scan that looks for endometriosis growing deeper than a routine pelvic ultrasound is designed to assess. This page explains what the scan is, what it looks for, what happens on the day, and how to arrange one.
A DIE scan — a deep infiltrating endometriosis ultrasound — is a detailed transvaginal ultrasound that systematically checks the pelvis for signs of deep endometriosis. “Deep infiltrating” endometriosis is disease that grows more than a few millimetres beneath the surface lining of the pelvis, often involving structures a standard scan does not set out to examine.
It is a longer and more structured examination than a routine pelvic ultrasound, performed by a clinician trained specifically in mapping endometriosis.
Accurate imaging is crucial in managing suspected endometriosis. A DIE scan helps the care team to:
Until recently, many women on the Central Coast needed to travel to Sydney to access this level of subspecialist ultrasound assessment.
The scan works through the pelvis in a set order, looking for signs of endometriosis and where it may be located, including:
A standard pelvic ultrasound mainly assesses the uterus, the lining of the womb and the ovaries. A DIE scan does all of that and then extends into a systematic search for deep disease that a routine scan is not designed to map. It usually takes longer and requires specific training to perform and interpret. The scan examines:
This detailed assessment provides critical information that is not typically captured on routine pelvic imaging and is essential for identifying deep disease.
Your doctor may recommend a DIE scan if you have:

The scan is performed transvaginally, meaning a slim ultrasound probe is gently placed into the vagina, which gives the clearest view of the pelvic structures. The sonologist works through the pelvis systematically and, at points, applies gentle pressure or asks you to help assess whether the organs move freely.
You can ask questions throughout, and you can ask to pause or stop at any time.
A DIE scan usually takes about 30 minutes — longer than a routine pelvic ultrasound, because the pelvis is examined systematically.
A transvaginal scan is usually well tolerated, but it can be uncomfortable, particularly if the area is already tender. The sonologist will explain each step, work gently, and stop if you need them to. If you are anxious about the scan, let the team know when you book.
A DIE scan can identify many signs of deep endometriosis and help show where it is. However, a normal scan does not rule out endometriosis. Some endometriosis, particularly superficial disease on the surface of the pelvis, cannot be seen on ultrasound, and diagnosis is sometimes only confirmed at laparoscopy (keyhole surgery). Your referring doctor will interpret the scan alongside your symptoms and any other tests.

Dr Sarika Gupta is a gynaecological ultrasound subspecialist who performs and reports your DIE scan herself — the images are not sent off-site for separate reporting, so your results can be discussed with you at the appointment. Dr Gupta is a female sonologist.

No. A DIE scan includes everything a standard pelvic ultrasound does, then extends into a systematic search for deep disease involving the bowel, bladder, ligaments and the mobility of the pelvic organs. It usually takes longer and needs specific training.
It is usually well tolerated but can be uncomfortable, especially if the area is tender. The sonologist works gently, explains each step, and will stop if you ask.
No. A DIE scan can find many signs of deep endometriosis, but a normal result does not exclude it — some endometriosis cannot be seen on ultrasound and may only be confirmed at laparoscopy.
