目的探讨应用全数字化血管造影机检查的图像质量及X射线剂量。方法500人次冠状动脉造影检查,常规拍摄左前斜位加头位或足位,右前斜位加头位或足位,必要时加摄蜘蛛位。结果采取支架植入治疗左前降支狭窄92例,左回旋支狭窄28例及右冠状动脉狭窄45例,冠状动脉微细血管显示佳,管腔内血栓、血管内膜撕裂、支架等显示清晰。结论全数字化血管造影机采集的图像佳,X线剂量较低。
Objective To investigate the image quality and X-ray doses examined using an all-digital angiography machine. Methods A total of 500 coronary angiography examinations were performed. The left anterior oblique position plus the head position or the foot position, the right anterior oblique position plus the head position or the foot position, and the spider position when necessary were photographed. Results Stent implantation was used to treat left anterior descending coronary artery stenosis in 92 cases, left circumflex stenosis in 28 cases, and right coronary artery stenosis in 45 cases. The coronary microvessels showed good results. The intraluminal thrombus, endocardium tear, and stents were clearly displayed. Conclusion The images collected by the all-digital angiography machine are good and the X-ray dose is low.
