摘要
目的初步探讨64排螺旋 CT 在健康人群中进行冠心病筛查的意义和方法。方法对286例40岁以上有至少一项冠心病危险因素的健康人进行64排螺旋 CT 心脏冠状动脉检查。使用东芝 Aquilion 64排螺旋 CT 机扫描,应用 TCOT 算法得到容积数据,对数据进行最大密度投影(MIP)、容积重建(VR)、多平面重建(MPR)、曲面重建(CURVE)和三维(3D)后处理,观察其对冠状动脉病变的显示,部分阳性患者与导管对照。结果 286例中发现239支血管不同程度狭窄,其中狭窄程度小于50%的138支血管,50%～75%的82支血管,大于75%的19支血管。进行导管检查的28例,并有12例做了支架手术。结论 64排螺旋 CT 心脏冠状动脉检查,是一种早期发现冠心病的快速、有效、安全、可靠、微创的检查和诊断方法。尤其对那些貌似健康无症状的冠心病患者,64排螺旋 CT 可以替代冠状动脉造影,将成为筛查冠心病的首选方法。
Objective To evaluate the value of 64-slice helical CT in screening of coronary artery heart disease among apparently healthy people and to explore the specific operation thereof. Methods Toshiba Aquilion 64-slice helical CT machine was used to scan the scope from the tracheal carina to cardiodiaphragmatic plain among 286 apparently healthy persons aged 40 -78, 188 males and 98 females, with at least one risk factor of coronary artery heart disease, after the contrast Iopamidol was injected. The data thus obtained underwent after-finishing screenage with the techniques of volume reconstruction, multiplanar reconstruction, curve planar reconstruction, and 3-D reconstruction so as to demonstrate the abnormalities of coronary artery. Twenty-eight persons with positive findings further underwent coronary angiography. Their results of coronary angiography were compared with those of the results of 64-slice helical CT. Results 239 of the 1523 branches of coronary artery in the 286 persons were diagnosed as with stenosis of different degrees, 138 being less than by 50%, 62 being by 50% -70%, and 23 being by more than 70%. Twelve of the 28 persons who underwent angiography received coronary stentt. Conclusion As a minimally invasive examination, 64-slice helical CT is valuable in early detection of asymptomatic coronary heart disease.
