Abstract:

BACKGROUND: Due to the long and winding characteristics of small intestine, the examination technique is ineffective. The lesions of small intestine are mainly protuberant. At present, double contrast examination is chiefly applied in imaging examination. In the recent years, with the wide application of multi-slice spiral computed tomography (CT), CT virtual endoscopy (CTVE) gets more and more used in hollow organ. The value of the two techniques needs a comparison to make it clearer.
OBJECTIVE: To evaluate the value of CTVE and double contrast examination in diagnosing small intestine pprotuberant lesions. 
METHODS: Isolated porcine small intestines were taken as samples. MSCT scanned the quasi circular protuberant Lesions whose simulated heights of the intestinal wall were 1-5 mm, 5-10 mm and 10-15 mm. CTVE imaging was made through work station. Then we made small intestinal air-barium double contrast examination. The experienced physician compared the diagnostic self-confidence and accuracy between the two methods by single-blind evaluation. 
RESULTS AND CONCLUSION: To the protuberant lesions less than 5 mm, the doctors were more confident in diagnosing by double contrast examination of small intestine than by CTVE. The diagnostic accuracy of the two methods has no statistic differences. CTVE and double contrast examination each have their advantages in diagnosing protuberant lesions of small intestine. The diagnostic accuracy can be improved by comprehensive application.
