Abstract:
Objective To evaluate the contrast-enhanced 64-slice spiral CT(64-SCT) features and pathologic findings of coloniccancer comparatively.Methods 56 cases of colonic cancer underwent 64-SCT dynamic enhancement scans.All cases were classifiedaccording to 64-SCT features of arterial phase and then analysed pre-operatively with pathological comparation.Results There werecharacteristic manifestations on arterial phase of contrast-enhanced CT scan in all cases,the tumors with well differentiation appeared as slight-medial homongeneous enhancement in 23 cases,while undifferentiation tumors appeared as obviously inhomogeneous enhancement or layer-like enhancement in 33 cases.The tumors were classified according to their features on contrast-enhanced CT,the accuracy rate was 91.07%,the accuracy rate evaluated pre-operation was 92.86%.Conclusion 64-SCT dynamic scan has distinctive superiority in diagnosis and treatment of the colonic tumor.
