Abstract: Objective To evaluate the clinical value of MSCTA in displaying the right gastroepiploic artery(RGEA).Methods 16-slice spiral CT enhanced images of abdomen in 80 cases were retrospectively reviewed.The course and the length of RGEA were observed and the diameters of RGEA at the origin and the end were also measured on maximum intensity projection(MIP),thin slice maximum intensity projection(TSMIP) and volume rendering(VR) images.Results The displaying rate of RGEA by MSCTA was 100% including long type in 22 cases(27.50%),moderate type in 53 cases(66.25%) and short type in 5 cases(6.25%).The average length of RGEAs was (19.5±4.5) cm.The average diameters of RGEAs at the origin in long,moderate and short type respectively were (2.69±0.26) mm,(2.70±0.18) mm,(2.68±0.12) mm respectively.The average diameters of RGEAs at the end in these three types were (1.76±0.17) mm,(1.75±0.18) mm and (1.74±0.05) mm respectively.The average diameters of RGEA in different length were no of statistical significance(P＞0.05).Conclusion RGEA can be evaluated with MSCTA before coronary artery bypass grafting.
