Abstract
Background: Invasive coronary angiography (ICA) is anatomical evaluation of coronary artery disease is considered gold standard. Aim of the study: to compare the diagnostic characteristics of non-invasive computed Tomography (CT) coronary angiography to invasive coronary angiography in diagnosis of coronary artery stenosis and their economic benefits. Patients and methods: This study was descriptive Observational study, thirty studied cases included in research. Patients are undergone ECG gated MDCT coronary angiography in CT unit in Radiology Department of National Heart Institute NHI was analyzed from PACS (Syngovia acquisition system) and we was included patients for detection of coronary stenotic lesions compared to outcomes of invasive coronary Angiography attached with patients including CABG patients. Result: the value of Sensitivity was (091.7percent), specificity (080.00percent), Positive predictive value (PVP) is 50.0 percent, negative predictive value (PVN) is 97.8%, & accuracy is 90.6 percent which means that CT angiography is a good screening tool for detection of degree of coronary arteries stenosis. Conclusion: In conclusion, this study revealed that CT angiography provided high sensitivity & negative predictive values in examination of coronary arteries, so it is good screening instrument for detection of degree of coronary arteries stenosis. However, moderate and severe coronary calcifications may interfere with diagnostic accuracy of the coronary artery.
