Chinese Abstract

目的:探討加注生理鹽水對16層螺旋CT冠狀動脈成像的作用。方法:60例患者被隨機分成兩組,1組:注入對比劑歐乃派克120ml;2組:注入對比劑歐乃派克100ml及生理鹽水40ml。所有患者均行16層螺旋CT冠狀動脈增強掃描,分別測量左、右冠狀動脈開口層面升主動脈、肺動脈及上腔靜脈的CT值,測量左冠狀動脈主幹、左前降支、左迴旋支及右冠狀動脈的CT值,並用統計學軟件SPSS分析。結果:升主動脈CT值1組顯著低於2組,上腔靜脈CT值1組顯著高於2組。肺動脈CT值在左、右冠狀動脈開口層面1組均高於2組,但差異在右冠狀動脈開口層面有顯著性意義,在左冠狀動脈開口層面無顯著性意義。各支冠狀動脈CT值1組均顯著低於2組。結論:加注生理鹽水可以節省對比劑,降低上腔靜脈及右心的密度,增加升主動脈的密度,便於更好地顯示冠狀動脈。

English Abstract

Objective: To investigate the impact of added saline in coronary angiography with 16-slice spiral CT. Methods: Sixty patients were divided into two groups by contrast material administration: group 1(120ml Omnipaque) and group 2(l00ml Omnipaque followed by 40ml saline). All patients underwent coronary angiography with 16-slice spiral CT. The attenuation of ascending aorta, pulmonary artery and superior vena cava was recorded on the original section of left and right coronary artery. The attenuation of the left main left anterior descending, circumflex and the right coronary artery was also assessed. The difference of attenuation was assayed by statistical SPSS software. Results: The attenuation of ascending aorta in group 1 was significantly inferior to group 2 and the attenuation of the superior vena cava in group 1 was significantly superior to group 2. The attenuation of pulmonary artery on the original section of the left and right coronary artery in group 2 was both inferior to group 1, but the difference was significant on the original section of the right coronary artery and not significant on the original section of the left coronary artery. The attenuation of the main coronary artery branches in group 1 was all significantly inferior to group 2. Conclusion: Using added saline could save the contrast material, decrease the enhancement of the superior vena cava and the right heart, increase the enhancement of the ascending aorta and display the coronary artery better.
