随着医学科学的飞速发展,16排多层螺旋 CT 将多层螺旋 CT 带入一个全新的领域。它比四层螺旋 CT 的扫描速度提高6倍,检查效率提高4倍,采集信息量增加4倍,节约一半球管的损耗,X 线剂量降低1倍,具有低消耗、低剂量、高速、高质量图像多功能等特点。1、可做无创冠脉造影成像:能清晰显示冠脉的各级分支及分布,显示冠脉软斑块的位置、范围及腔内的情况。对冠脉搭桥术和支架进行无创准确的评估,其显示冠状动脉狭窄的准确性高。2、肺肿瘤的普查:16层螺旋 CT以其较佳的密度分辨力结合低剂量扫描技术,约90%以上的肺癌能早期发现;并能提供精确的肺结节增长率和倍增时间的定量分析、生长情况,判断
With the rapid development of medical science, 16-row multi-slice spiral CT has brought multi-layer spiral CT into a whole new field. Compared with four-slice spiral CT, the scanning speed is increased by 6 times, the inspection efficiency is increased by 4 times, the amount of information collected is increased by 4 times, and the loss of half of the tube is saved. The X-ray dose is reduced by 1 time, with low consumption, low dose, high speed, high Quality features such as features. 1. Non-invasive coronary angiography imaging: It can clearly display the branches and distribution of coronary arteries at various levels, and shows the position, scope, and cavity status of coronary soft plaques. Non-invasive and accurate assessments of coronary artery bypass grafts and stents show high accuracy of coronary artery stenosis. 2. General survey of lung tumors: 16-slice spiral CT with its better density resolution combined with low-dose scan technology, approximately 90% of lung cancers can be detected early; and can provide accurate lung nodule growth rate and doubling time quantification Analysis, growth, judgment
