Abstract
目的 探讨通过服用硝酸甘油提高多层螺旋CT(MSCT)冠状动脉成像显影质量的可行性.方法 选服用与不服用硝酸甘油患者各30例,用16层MSCT扫描,对比2组患者冠状动脉13个节段显影的差异.并将服用硝酸甘油患者中10例进行了DSA选择性冠状动脉成像的图像进行对比.结果 (1)2组在冠状动脉13个血管节段中,右冠状动脉(第1、2、3段)、左主干(第5段)、左前降支(第6、7段)、左旋支(第11段)可评价血管例数相同(均为30例);后降支和左室后支(第4段,X2=8.007,P=0.004)、左前降支(第8段,X2=8.571,P=0.003)、第1对角支(第9段,X2=6.667,P=0.010)、第2对角支(第10段,X2=38.400,P=0.000)、钝圆支(第12段,X2=12.000,P=0.001)、左旋支(第13段,X2=10.335,P=0.001)的显影差异有统计学意义.(2)服用硝酸甘油MSCT冠状动脉成像10例与选择性冠状动脉成像初步对比,严重的钙化和运动伪影影响狭窄的准确性,轻度钙化或无钙化和无运动伪影时,MSCT冠状动脉成像与DSA冠状动脉成像结果吻合.结论 使用硝酸甘油可提高MSCT冠状动脉成像的显影质量。
