Medical imaging using X-rays.
CT enterography (CTE) is a non-invasive technique for the diagnosis of small bowel disorders.
Indications for CT enterography include:
most common indication
suspected small bowel bleeding, usually performed after negative endoscopy
suspected small bowel tumor, e.g. carcinoid, polyposis syndromes
celiac disease: assess for complications such as lymphoma
partial small bowel obstructions, e.g. postoperative adhesions, radiation enteritis, scleroderma
chronic diarrhea and/or abdominal pain.
Inflammatory Bowel Disease (IBD): To assess the extent and severity of conditions such as Crohn’s disease or ulcerative colitis, which can cause inflammation and damage to the gastrointestinal tract.
Evaluation of Abdominal Pain or Discomfort: If you are experiencing chronic or unexplained abdominal pain, a CT enterocolonography can help identify the cause, including conditions such as diverticulitis, colorectal cancer, or other gastrointestinal disorders.
Colorectal Cancer Screening: As a non-invasive alternative to traditional colonoscopy, CT enterocolonography can be used for colorectal cancer screening, especially in individuals who are unable or unwilling to undergo a colonoscopy.
Assessment of Bowel Obstruction: To evaluate the presence and cause of bowel obstructions, which can be due to tumors, adhesions, or other conditions.
Detection of Polyps and Lesions: CT enterocolonography can identify polyps, lesions, or abnormalities in the colon and small intestine.
Monitoring Treatment Response: For individuals with known gastrointestinal conditions, a CT enterocolonography may be performed to monitor the response to treatment and assess disease progression or regression.
Evaluation of Gastrointestinal Bleeding: To locate the source of gastrointestinal bleeding, helping healthcare providers determine the appropriate course of action.
Assessment of Complications: In cases of known gastrointestinal conditions or surgeries, a CT enterocolonography can help assess for complications such as strictures, fistulas, or abscesses.
