Multidetector computed tomography enteroclysis (MDCT-E) with neutral enteral and IV contrast enhancement in tumor detection

The aim of our study was to evaluate the reliability of MDCT-enteroclysis (MDCT-E), an emerging technique of small bowel examination that combines the advantages of MDCT examination of the abdomen and the enteral volume challenge of enteroclysis, in evaluation of small bowel neoplasms.

Description
Summary:The aim of our study was to evaluate the reliability of MDCT-enteroclysis (MDCT-E), an emerging technique of small bowel examination that combines the advantages of MDCT examination of the abdomen and the enteral volume challenge of enteroclysis, in evaluation of small bowel neoplasms. In our institutions, MDCT-E was used to study 456 patients (age range 21-84 years, mean 53 years) admitted for suspicion of small bowel disease. All examinations were done on multichannel CT units, 129 on a 16-slice scanner and 327 on a four-slice scanner. Post-processing and multiplanar reformatting and interpretation were performed on dedicated workstations. After adequate gastrointestinal preparation and naso-enteric intubation, small bowel was distended by methylcellulose infused by a peristaltic pump. One volumetric MDCT acquisition was obtained after 120-130 ml of intravenous contrast medium. Multiplanar reformatting was based on the image reconstruction parameters from 3 to 4 mm. Forty-five small bowel neoplasms were found; in the remaining cases, 223 Crohn's diseases and 149 other abnormalities were detected. All findings were confirmed by surgery, endoscopy or clinical follow-up. In our experience, MDCT-E with neutral enteral and IV contrast seems to be a reliable method in the diagnosis of small bowel neoplasms.
