[|AI|]  Hi. It is good to know that you are a nursing student and want to know more. MRI and CT scan have limited role in the diagnosis of the Peptic ulcer, not much indicated as the oral contrast should not be given in such cases. They will find collection of fluid inside the peritoneal cavity. In Laparoscopy, you will find the perforation, and pus filled peritoneal cavity, may be adhesions too. The best simple diagnostic tool is X-ray of the abdomen in the standing position to find gas under diaphragm. This is a sure sign of a Perforation.
