摘要
健康成年雄性滇南小耳猪12头,行经皮球囊堵闭法制备急性心肌梗死动物模型,分组分别取仰卧位及侧卧位,于术前及术后6 h行双源CT心肌灌注成像。结果显示:1双源CT心肌灌注成像能够清晰显示猪冠状动脉解剖结构及其主要分支,90.9%血管可用于诊断。2采取仰卧位动物模型显示节段76个,1级图像58个;侧卧位动物模型显示节段94个,1级图像85个。3影响图像质量的因素主要为心率及呼吸伪影。
12 healthy male adult Diannan Smalleared Pigs were chosen. Swine models of acute myocardial infarc- tion were prepared by coronary obstruction with percutaneous transcoronary angioplasty（ PTCA）. Swine models were grouped of supine position and lateral position. All models were taken dual-source CT myocardial perfusion imaging scan before PTCA and 6 hours after operation. The imaging technology, imaging quality and influencing factor of quality were discussed. The results showed that：① Dual-source CT myocardial perfusion imaging could show the structure of swine coronary artery and its branches. 90.9% segments could be used for diagnosis. ②For the groupof supine position, 76 segments were showed, 58 segments were judged level 1. For the group of lateral position,94 segments were showed, 85 segments were judged level 1. ③ The main influencing factors of imaging quality were heart rate and artifacts of respiration.
