在动态CT扫描中,静脉团注造影剂的增强方法明显优于非加压滴注法,但仍然有许多人认为此法会产生并发症而不愿使用。笔者报道680例在CT增强的扫描中应用高压注射器的体会,以说明此技术的可行性。 1 材料与方法 680例病人的增强全部使用60％泛影葡胺注射液(离子型造影剂)。采用在压力控制范围内注射。分别采用30ml/min、40ml/min、50ml/min、60ml/min等4个不同预先设置好的注射量。根据检查部位不同进行常规体位的安置,以12号针头穿刺手臂静脉,通过三通管连接0.9％生理盐水250ml及高压注
In dynamic CT scans, contrast-enhanced bolus injection is significantly better than non-pressurized drip, but there are still many people think that this method will produce complications rather than use. I report 680 cases of CT-enhanced scan using high-pressure syringe experience to illustrate the feasibility of this technology. 1 Materials and Methods 680 cases of patients with enhanced use of all 60% meglumine meglumine (ionic contrast agent). Used in the pressure control range of injection. Respectively, using 30ml / min, 40ml / min, 50ml / min, 60ml / min 4 different pre-set injection volume. According to the different parts of the examination for the placement of conventional position to 12 needle puncture arm vein through the tee tube connected 0.9% saline 250ml and high pressure injection
