Abstract
Objective: To study the clinical value of colorectal carcinoma examination by comparison of different postprocessing techniques such as multiplanar reformation (MPR), CT virtual colonoscopy (CTVC), shaded surface display (SSD) and Raysum. Methods: 64 patients with colorectal carcinomas underwent volume scanning using spiral CT. MPR, CTVC, SSD and Raysum images were obtained by using 4 different software in workstation. All cases were proved by surgical or CC biotic histology. The results were compared and analyzed according to the circumferential extension, length and pathologic patterns of colorectal carcinoma with MPR, CTVC, SSD and Raysum. Results: The correction rate of determination the circumferential extension of colorectal carcinoma with MPR, CTVC, SSD and Raysum were 100.0%, 82.8%, 79.7% and 79.7%, respectively. There was significant statistical difference between MPR and CTVC; The accuracy of judging the length of carcinoma were 89.1%, 76.6%, 95.3% and 100.0%, respectively. There was statistical difference between CTVC and SSD; The accuracy of showing carcinoma pathologic patterns were 81.3%, 92.2%, 71.9% and 71.0%, respectively. There was statistical difference between CTVC and SSD, too. MPR could correctly determine the circumferential extension of colorectal carcinoma. In determination the length of carcinoma, Raysum was more accurate than SSD. CTVC could be more helpful in
