What is an MRI of the Whole Abdomen?
An MRI of the whole abdomen covers both the upper and lower abdominal compartments in a single comprehensive examination — imaging the liver, gallbladder, pancreas, spleen, kidneys, adrenal glands, small bowel, large bowel, bladder, uterus, ovaries, and prostate in one session. It is a thorough, radiation-free investigation that provides a complete survey of all abdominal and pelvic organs, and is particularly useful when the clinical problem is not clearly localised to one organ.
Why is a Whole Abdomen MRI Done?
- To stage cancers that can spread throughout the abdomen — including colorectal cancer, ovarian cancer, and lymphoma
- To investigate abdominal pain or mass when the organ of origin is unclear
- To evaluate peritoneal disease — peritoneal metastases or carcinomatosis
- To assess multiple organ involvement in inflammatory conditions such as Crohn's disease or systemic vasculitis
- As a comprehensive radiation-free alternative to CT for patients requiring repeated follow-up imaging
- To evaluate abdominal and pelvic organs simultaneously when both regions need assessment
How to Prepare for a Whole Abdomen MRI
- Fast for 4–6 hours before the scan — fasting reduces bowel peristalsis artefact and improves image quality throughout
- Your doctor may prescribe an antispasmodic injection (buscopan) just before the scan to reduce bowel movement — inform them about any glaucoma or prostate problems before this is given
- A moderately full bladder is usually helpful for pelvic organ visualisation — drink water 30–60 minutes before arrival
- If contrast is planned, a serum creatinine test is required beforehand
- Remove all metal objects and inform staff about pacemakers or abdominal implants
- Bring previous CT, ultrasound, and any relevant laboratory reports for comparison
