摘　　要：目的 :对冠状动脉钙化进行定性判断 ,并对其钙化程度进行积分评估和相关技术探讨。方法 :采用GELightspeed 2 .0螺旋CT ,结合心电门控技术 ,对临床怀疑冠心病及要求体检者共 16例行心脏平扫。结果 :CT成像 ,应用SmartScore软件行冠状动脉钙化积分评估。 9例可见双侧冠状动脉多发钙化 ,3例高积分病例随后行DSA检查 ,进一步判断冠脉狭窄程度 ;3例单支冠状动脉钙化 ;4例未见明显钙化 ,其中 1例右侧冠状动脉密度增高 ,有粥样硬化斑块。结论 :螺旋CT冠状动脉钙化积分评估 ,可作为临床诊断重要辅助参考依据 ,是一种值得推广的技术。Objective:To study the value of double slice spiral CT in evaluation of the coronary artery calcification scores. Methods:Sixteen patients with suspected coronary artery disease were performed double slice spiral CT with ECG gating technique. The CT scans were evaluated with SmartScore software.Results:There were multiple calcifications in both coronary arteries in 9 cases,3 cases with high scores of them accepted DSA examination later. 3 cases had calcification of single coronary artery. In 4 cases no calcification was observed,but there was increased density of the vessel with atherosclerosis in one of them. Conclusion:Double slice spiral CT of the heart is a reliable technique in evaluation of the coronary artery calcification scores and useful for the clinical diagnosis.
