Objective To assess the value of 64-slice CT colonography (CTC) in diagnosing colorectal neoplasms. Methods One hundred and thirty-two patients with suspected colorectal neoplasm underwent 64-slice spiral CT after bowel cleaning and rectal air insufflating, double contrast barium enema (DCBE) and colonoscopy. CT data were transmitted to the workstation and was performed respectively. All images were separately evaluated by two experienced radiologists. The sensitivity, specificity and accuracy of the CTC and DCBE were evaluated and compared with that of colonoscopy or surgical biopsy. Results The sensitivity, specificity and accuracy of CTC was 96.49%, 90.91% and 95.59%, of DCBE was 91.23%, 72.73% and 88.24% (χ~2=0.566, P=0.319). In neoplasms with diameter ≤5.0 mm, the sensitivity, specificity and accuracy of CTC was 80.95%, 86.96% and 84.09%, of DCBE was 57.14%, 69.56% and 63.64% (χ~2=0.679, P=0.422). In neoplasms with diameter of 5.1-9.9 mm, the sensitivity, specificity and accuracy of CTC was 91.67%, 100% and 94.12%, of DCBE was 75.00%, 80.00% and 76.47% (χ~2=0.631,P=0.374). The sensitivity, specificity and accuracy of both CTC and DCBE for detecting neoplasms with diameter ≥10.0 mm was 100%. Conclusion CTC is valuable in detecting colorectal neoplasm as a noninvasive method.
