64排螺旋CT冠状动脉造影术在冠心病临床诊治中的应用

目的：探讨研究64排螺旋CT冠状动脉造影术在冠心病患者的临床诊治中的应用。方法：选取20例冠心病患者进行64排螺旋CT冠状动脉造影术,并同传统的选择性冠状动脉造影（CAG）检查结果进行比较。结果：64排螺旋CT冠状动脉造影术对1～3级冠状动脉分支的显示情况较好（100%,100%,85%）,但对4级冠状动脉分支显示结果不佳（50%）。64排螺旋CT与CAG诊断冠状动脉狭窄程度〈50%与≥50%的一致率分别为89.4%与94.4%。结论：多层螺旋CT技术作为一种安全、可靠和无创的影像学技术,可作为诊断冠心病及介入治疗前预案制订的首选方法,但必要时仍需进行数字减影血管造影检查作为对比,以提供辅助信息从而为冠心病的临床诊治提供更为准确的判断。

The application of 64-slice spiral CT coronary angiography in diagnosis and treatment of the coronary heart disease

Objective： To discuss the application of 64-slice spiral CT coronary angiography in patients with coronary heart disease.Methods： 20 cases of patients with coronary heart disease（CHD） had been chosen,and all patients were implemented 64-slice CT angiography.The images and diagnosis results were compared with traditional selective coronary angiography（CAG）.Results： 64-slice sprial CT had preferably show on grade 1-3（100%,100%,85%） of coronary artery branches than grade 4（50%）.Compared with traditional CAG the 64-slice spiral CT coronary angiography diagnosed of narrow degree of concordance rate of 50% and ≥50% were 89.4% and 94.4%.Conclusion： As a safe,reliable and non-invasive imaging techniques,64-slice sprial CT is the first choice to diagnose CHD disease,but some times it still needs traditional CAG to offer auxiliary information for accurate diagnosis.
