Abstract:
70 bpm during scan),the proportion of segments that could not be assessed because of motion artifact were 0.1%(1/759),1.1%(7/649),2.5% (10/407),42.6%(103/242),and 75.5%(108/143),respectively.With conventional selective coronary angiography as the golden standard,the sensitivity,specificity,positive and negative prediction values to detect≥50% stenotic lesions in the assessable segments were 79.2%,96.0%,83.8%,and 94.6%,respectively.There was a significant correlation between the number of segments per patient not assessable because of motion artifact and heart rate during the scan(r=0.655,P=0.000).Conclusion MSCT is capable of achieving high accuracy for detection of coronary artery stenosis,and is a reliable technique to diagnose coronary artery disease.
