[Comparison of non-invasive electron-beam and multislice CT angiography efficacy for detection of coronary artery stenosis].
OBJECTIVE
To compare diagnostic value of electron-beam CT (EBT) and multislice CT (MSCT) angiography in detection of coronary artery stenosis in patients with coronary artery disease (CAD).


METHODS
140 CAD patients who had undergone EBT (n = 97) or 4-slice CT (n = 43) coronary angiography and conventional coronary angiography as a gold standard were included in the study.


RESULTS
Sensitivity and specificity of EBT angiography in coronary stenosis detection (proximal and mid segments) were 86 and 97%, respectively. Sensitivity and specificity of MSCT angiography were 87 and 98%, respectively. 6 and 7% of coronary segments were excluded from the study because of bad image quality in EBT and MSCT groups, respectively.


CONCLUSIONS
No significant difference was registered in diagnostic value of EBT and 4-slice MSCT angiography in coronary artery stenosis detection.
