A Deep Infiltrating Endometriosis (DIE) scan is a specialised type of detailed pelvic ultrasound used to assess for deep endometriosis. This form of ultrasound focuses on areas where endometriosis may extend deeper into pelvic structures, rather than only assessing the uterus and ovaries. For patients experiencing ongoing pelvic symptoms, a DIE-focused ultrasound may form part of the broader imaging assessment recommended by a GP or specialist. How Is a DIE Scan Different from a Pelvic Ultrasound? Standard Pelvic Ultrasound A standard pelvic ultrasound is commonly used as a first-line imaging test and typically assesses: The uterus The ovaries General pelvic structures DIE Scan A DIE scan is more specialised and may include: Assessment of the bowel and rectal region Evaluation of the bladder Assessment of pelvic ligaments Evaluation of pelvic organ mobility What Does a DIE Scan Assess? A DIE-focused ultrasound may help assess for features associated with deep endometriosis, including: Areas of tissue thickening or nodules Reduced movement between pelvic organs, which may suggest adhesions Changes in the position or mobility of pelvic structures Imaging findings are interpreted alongside your symptoms, examination findings, and clinical history. A scan result is only one part of the overall assessment. When Might a DIE Scan Be Recommended? Your GP or specialist may request a DIE scan if there are symptoms such as: Persistent or severe pelvic pain Pain during intercourse Pain with bowel movements Bowel or bladder symptoms related to your cycle Known or suspected endometriosis The type of imaging requested depends on the clinical assessment and individual needs. Not every patient with pelvic pain will require a DIE-focused examination. How Is a DIE Scan Performed? A DIE scan is typically performed using a transvaginal ultrasound, often combined with a transabdominal component. This allows closer visualisation of pelvic structures and areas where deep endometriosis may occur. Part of the Examination What It May Involve Transabdominal ultrasound An external ultrasound over the lower abdomen Transvaginal ultrasound Closer assessment of pelvic structures using an internal ultrasound probe Mobility assessment Evaluation of the movement and relationship of pelvic organs where clinically relevant The examination is performed by trained sonographers and reported by a radiologist as part of the diagnostic imaging process.
