Comparison of Diagnostic Performance of Multi Detector CT Angiography with Conventional Coronary Angiography for Assessment of Coronary Artery Disease

Surya Narayan Bayar and Qian Yin Feng

Aim: The point of this study was to reflectively assess the analytic exactness of multi detector angiography as a different option for conventional coronary angiography in evaluating coronary artery disease.

Materials and Methods: This review study selected 57 patients, who experienced both conventional coronary angiography (CCA), and additionally multi-detector computed coronary angiography (MDCT). Aggregate of 931 open segments were studied. Of which 95 portions indicated shifted level of stenosis, with 34 segments <50% stenosis, 43 segments 50-70% stenosis and 18 segments >70% stenosis.

Results: The affectability and specificity of 64 slice MDCT for identifying stenosis in <50%, 50-70% and >70% are 78.57% and 99.34%; 81.08% and 99.33%; 87.5% and 99.78%. The positive predictive value (PPV) and negative predictive value (NPV) are 78.57% and 99.34%; 83.33% and 99.22%; 87.5% and 99.78% individually. Over all exact nesses are 88.95%, 90.2% and 93.64% separately. There was no critical contrast in analytic exactness between conventional coronary angiography and 64 slice computed tomography in moderate (50-70%) and additionally severe (>70%) stenosis (p>0.05). Be that as it may, critical contrast was found in gentle (<50%) stenosis (p<0.05).

Conclusion: Indicative exactness of multi detector coronary angiography (MDCT) was found to be higher in moderate and extreme stenosis and can be utilized as a substitute to conventional coronary angiography (CCA).
