The following exams all require special patient preparation:

  • abdomen
  • abdomen and pelvis
  • adrenals
  • bowel
  • colon
  • liver
  • pancreas
  • small bowel study
  • urinary bladder

The preparation advice is different for patients with diabetes than those without diabetes. Make sure you follow the correct advice for you. 

Non-Diabetic Patients 

Please do not eat or drink anything (except sips of water) for 4 hours before your appointment time. 

You can continue to take your usual medication.
 
Before entering the magnetic field, you will be required to remove all metallic objects, jewellery and items such as bank cards. These can be stored securely during your scan. 

You will also be required to remove any skin patches e.g., nicotine or hormone patches, and body piercings. 

If possible, wear clothing without any metal fasteners or zips – this may avoid having to change into a gown. 

It is safe to scan if you have any metal joint replacements such as a hip or knee replacement.
