摘要/Abstract

摘要： 目的探讨双源CT检测窦房结动脉的价值及其临床意义。方法选择利用双源CT进行冠状动脉成像的成人207例，根据窦房结动脉显示的长度和清晰度进行评分和分级、评价双源CT对窦房结动脉的显示情况。对窦房结动脉的直径、开口与其起源的冠状动脉起点之间的距离（SO间距）进行测量，观察窦房结动脉开口处冠状动脉壁钙化对窦房结动脉显示情况及管径的影响。结果共显示239支窦房结动脉，其中右侧型、左侧型、双侧型分别占64.3%、20.3%、15.5%。左、右窦房结动脉显示良好率分别为77.0%和81.2%。正常窦房结动脉的平均直径约为(0.20±0.04)mm，当窦房结动脉开口处的冠状动脉壁出现钙化时其直径为(0.18±0.03)mm，具有统计学差异（t＝2.558，P=0.011）。同时，钙化也影响窦房结动脉长度、清晰度及总体情况的显示(P＜0.05)。结论双源CT是显示窦房结动脉的良好方法，冠状动脉钙化可能影响窦房结动脉的血供。

Abstract: ObjectiveTo detect the sinus node artery (SNA) in adults with dual source CT. MethodsTwo hundred and seven cases that had undergone dual source CT coronary artery angiography were included in this study. The visualized grades of SNA were accessed by two radiologists based on the length and delineation of SNA on CT images. The diameter of SNA and the length from the origin of SNA to the origin of the coronary artery were measured. The relationship of calcification on the coronary artery wall around the origin of SNA with the diameter and the visualized grade of SNA were also analyzed. ResultsThe detected ratio of left, right and bilateral types of SNA was 64.3%, 20.3% and 15.5 % respectively in a total of 239 SNA, and the best visualization of left and right SNA was 77.0% and 81.2%. The normal SNA diameter was (0.20±0.04)mm, however it was (0.18±0.03)mm when calcification occurred on the coronary artery wall around the origin of SNA(t＝2.558, P=0.011). In addition, calcification also affected the observation of SNA such as length and delineation (P＜0.05). ConclusionA good way to detect SNA is by using dual source CT, and calcification on the coronary artery may affect the blood supply of SNA.
