| 摘 要： | OBJECTIVE To investigate the value of CT colonography (CTC) in diagnosis and preoperative staging of colorectal carcinoma. METHODS CTC was performed on 33 patients who were suspected of having colorectal carcinoma. The results of CTC were compared with those of a pathological examination. RESULTS Among the 22 patients who were diagnosed with colorectal carcinoma by CTC, 20 cases were confirmed by pathology. The diagnostic sensitivity and specificity were 100% (20/20) and 84.6% (11/13) respec- tively. The accuracy of showing carcinoma pathologic patterns was 90% (18/20). The sensitivity and specificity were both 100% in the mass type; 77.8% and 100% in the infiltrating type; 100% and 85.7% in the ulcerated type. The accuracy of staging Dukes' carcinoma was 75%. The sensitiv- ity and specificity were 100% and 94.1% for Dukes'A; 80% and 73.3% for Dukes' B; 60% and 100% in Dukes' C; 71.4% and 100% for Dukes' D. CONCLUSION CTC produces a high success rate and provides con- siderable diagnostic information for both an accurate diagnosis of colorectal carcinoma and staging before operation.
