作者评价了胸主动脉增强CT多平面和三维重建对术前制定治疗方案的价值。53例胸主动脉病变患者采用螺旋扫描方式采集数据,用19号针经肘静脉注入对比剂Iopramide(300mg/ml)100ml。扫描方式或采用5ml/s的快速手推注射,在注入40ml后即开始扫描,或是在100ml团注后立即扫描。扫描层厚5～10mm,螺旋CT的螺距为1,扫描间隔15～20s。图像用Advantage Windows1.2重建。对 The authors evaluated the value of thoracic aortic enhancement CT multiplanar and three-dimensional reconstruction in the development of preoperative therapies. Fifty-three patients with thoracic aortic lesions were enrolled in a spiral scan, and 100 ml of contrast agent Iopramide (300 mg / ml) was injected through the elbow vein with a 19 gauge needle. Scan mode or using 5ml / s rapid hand-push injection, after the start of the injection of 40ml scan, or 100ml bolus immediately after the scan. Scanning layer thickness 5 ~ 10mm, helical CT pitch 1, scan interval 15 ~ 20s. Image using Advantage Windows1.2 reconstruction. Correct
