Computed Tomographic Colonography (CTC)–Diagnostic With and Without Contrast
Computed Tomographic Colonography (CTC)–Diagnostic With and Without Contrast Exam Computed Tomographic Colonography (CTC)—Diagnostic With and Without Contrast Clinical History 45-year-old woman who presents with abdominal pain and is referred for CTC post-incomplete colonoscopy. The referring physician believes that because of prior hysterectomy, colonoscopy could not be completed due to probable scarring. Technical Information The patient arrived for the CT following conventional bowel preparation and stool tagging the day before the procedure. A small conventional barium tip was placed per rectum, with automated insufflation of carbon dioxide. Supine and prone images were acquired at 2.5-mm effective slice thickness and...
