Usefulness of preoperative CT colonography for colon cancer

CT Colonography (“Virtual Colonoscopy”) for Colon Cancer Screening

Background: Computed tomographic (CT) colonography, also known as "virtual colonoscopy," is an imaging technique of the colon involving helical computed tomography and computer software to generate high-resolution 2-dimensional and 3-dimensional images of the inner surface of the colon. These images are then interpreted by a radiologist to determine the presence of several types of abnormalitie...

The Association of Anisakiasis in the Ascending Colon with Sigmoid Colon Cancer: CT Colonography Findings

The association of anisakiasis of the colon with colon cancer is rare and difficult to diagnose. Only one case of this type has been reported to date. In this study, we report a case of synchronous colon cancer and colonic anisakiasis. A 50-year-old woman was admitted for abdominal pain, and a volume-rendered surface-shaded image of CT colonography (CTC) revealed a concentric narrowing in the s...

Incomplete Colonoscopy in Patients with Occlusive Colorectal Cancer: Usefulness of CT Colonography According to Tumor Location

PURPOSE We sought to evaluate the clinical usefulness of CT colonography (CTC) after incomplete conventional colonoscopy (CC) for occlusive colorectal cancer (CRC) according to the tumor location. MATERIALS AND METHODS Seventy-five patients with occlusive CRC underwent subsequent CTC immediately after incomplete CC. Fifty-nine patients had distal CRC and 16 had proximal colon cancer. Experien...

3D Colon Object Reconstruction Framework in CT Colonography

Colorectal cancer, also called colon cancer or bowel cancer, includes cancerous growths in the colon, rectum and appendix. It is the second leading cause of death caused by cancers and the third most common form of cancer in the United States [1]. Computer tomographic colonography (CTC) is a minimally invasive technique and rapidly evolving diagnostic tool for the location, detection and identi...
