OVERVIEW
This page serves as a guide to jejunostomy tubes (J-tubes) that are used within the field of interventional radiology. Fundamentally, a J-tube is a literal tube that connects the outside environment to the inside of the patient’s bowel. It is inserted percutaneously, transversing the wall of the jejunum, as well as the abdomen. Often times it is used to provide nutrition to the patient (by injecting it directly into the bowel). Look on this page to see how this piece of medical equipment will appear on various imaging modalities.
