Coronary Artery Stenosis: Comparison with 64 Volume Cardiac CT Angiography and Conventional Cardiac angiography

Purpose The author evaluated the coronary artery stenosis of using 64 volume cardiac CT angiography(CTA) compared with conventional cardiac angiography(CA) for the assessment of CTA detection accuracy. Materials and Methods This study induded 18(13 men, 5 worren)patients who underwent both CTA and CA to evaluate coronary artery stenosis of January to July 2006, and two study of during the seven days. We used 64 Volume CT(40mrn detector coverage, 0.625mm thickness, 0.2:1~0.24:1 pitch, 120kvp, 650mA), between the intravenous injection of contrast medium 70-90ml(Iopamidol 370, 4 mL/sec). Scan row data are acquired conticuously images can be reconstructed ten grade R-R interval(5-95%) transfer the 4.2 advantage workstation, and obtained 3 dimensional image. One radiologist and one cardiologist report of the classification of LAD, LCX, RCA with assessment of this artery stenosis of CTA detection accuracy.. Results The 64 volume CTA detected coronary artery stenosis of 79.6%(43 of 54) of all 54 cases conventional coronary angiography, with LAD stenosis of 83.3%(15 of 18), LCX stenosis of 77%(14 of 18), RCA stenosis of 77.7%(14 of 18). Conclusion 64 Volurre Cardiac CT Angiography is good noninvasive technique of very useful inspection to evaluated coronary artery stenosis.
