Abstract:
Small bowel angioedema is a rare adverse effect of iodinated contrast medium. Here, we report the first case of contrast medium-induced small bowel angioedema with concurrent respiratory tract symptoms. A patient with colon cancer underwent CT scanning for preoperative staging. After injection of the contrast medium, a persistent cough developed and CT images showed that the small bowel wall was abnormally thickened. It returned to normal by the follow-up. The persistent coughing that developed right after the CT and small bowel wall thickening on the contrast-enhanced CT suggested the diagnosis of small bowel angioedema induced by the contrast medium.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
