An MRI scan is an excellent way of looking at the structures, not the function, of the intestinal tract and the rest of the organs in the abdomen and it is very helpful for looking at structural abnormalities such as scarring and strictures of the gut.
It can also image the structures of the liver and pancreas and then it is called an MRCP.
These scans can take some time, be noisy and require patients to lie very still and hold their breath at times. Therefore, for younger children it will require a general anaesthetic, but for older children who can usually lie still, it can be easily performed in a 30-60 minute period of time.
There aren’t any side effects and it doesn’t involve radiation.
