The clinical values of 64-detect computed tomography coronary angiography

Objective:To evaluate the clinical values of 64-slice computed tomography coronary angiography(64SCTCA) in contrast to conventional coronary angiography(CCA). Methods:Thirty-five patients with 64SCTCA detected coronary artery stenosis were,using volume representation,surface reconstruction,maximum density projection techniques restructuring image shows the coronary artery main branch and the main branches,and X-ray coronary artery imaging(CCA) compared with the results of the analysis. Results:64SCTCA showed 90 lesions.Of them,85 lesions were consisted with CCA,22 lesions falsely positive and 10 lesions were fond by CCA not picked up by 64-slice CTCA.There was no obvious difference in the discovery of CAD between 64SCTCA and CCA. Conclusions: 64SCTCA has high accuracy in detecting coronary artery stenoses,as a noninvasive method,it can be used for screening patients with coronary artery diseases.
