摘要 目的:对比评价常规CT扫描与胸部能谱成像应用于临床检查时的射线辐射剂量与图像质量。方法:将医院2017年1月~4月收治因病情需要行胸部CT检查的52例患者作为研究对象,患者均行常规CT平扫与胸部能谱成像扫描,并对两种CT扫描方式的辐射剂量与图像质量进行比较,以评价最佳扫描方式。结果:不同CT扫描方式比较可见,常规CT平扫与能谱动脉期成像的辐射剂量及图像质量相当(P>0.05);而能谱静脉期成像虽然比常规CT平扫有较高辐射剂量,但所提供的图像质量也更佳(P<0.05)。结论:与120k Vp常规CT平扫相比,胸部动脉期能谱成像的辐射剂相当,胸部静脉期能谱成像虽然有较高辐射剂量,但所获得的图像质量,可在临床酌情考虑应用。
