- Abstract
Background: Multi-slice computed tomography of the coronary arteries have been shown promising results, regarding the detection of coronary artery disease, as well as an alternative tool for interventional coronary procedures, Multi-slice computed tomography of the coronary arteries is currently considered the ideal tool to threedimensionally visualize the complex and tortuous anatomy of coronary arteries. Before coronary revascularization procedures, precise evaluation and description of the coronary artery tree is greatly needed by Multi-slice computed tomography of the coronary arteries Aim : To assess the role of multi-detector computed tomography (MDCT) coronary angiography with multi-planar reformation (MPR) and three-dimensional (3D) reconstruction in the evaluation of anatomic variations of coronary arteries. Method: this study was cross-sectional and was carried out at the radiodiagnosis department, Zagazig university hospitals, A total number of 87 patients with normal heart rates were scheduled for elective multi-detector computed tomography of coronary angiography in the period from June 2018 to February 2019. Result:Our study reported coronary dominance was found to be right-sided in 83.3 %, left-sided in 6.7 %, and co-dominant in 10 % of our study group. And left main coronary artery branching pattern shows that type IV of the left anterior descending artery (36.7%) was the commonest variant and also a variable number of diagonals were observed. On the other hand, the right coronary artery branching pattern shows that one acute marginal branch was been in 73.3%, Regarding the second variant of the right coronary artery shepherd's crook coronary artery is noted in 3.3% of cases, and also conus artery originated from proximal right coronary artery seen in (58.3%). Conclusion: This study has shown that computed tomography of coronary angiography is an excellent non-invasive modality in the diagnosis and delineation of coronary arteries and can offer valuable information about the coronary arterial system regarding its normal variants.
