作者共收集79例非急诊胸部CT检查的病例,女41例、男38例,平均年龄57岁。每例均扫描2次,第一次为5mm层厚平扫,从主动脉弓至右中叶支气管水平连续扫描;第二次为10mm层厚连续动态扫描,从肺尖直至通过肾上腺,用高压注射器注入对比剂100～120ml(1.5～2.0ml/s,50ml,然后用0.8～1.0ml/s,延迟45s)。图像均为标准算法重建,分别用 The authors collected a total of 79 cases of non-emergency chest CT examination, 41 females, 38 males, mean age 57 years. Each case was scanned twice, the first time for the 5mm layer thickness scan, aortic arch to the right middle of the bronchus continuous scanning; the second 10mm layer thickness continuous dynamic scan from the apex to the adrenal, high pressure syringe injection contrast 100 to 120 ml (1.5 to 2.0 ml / s, 50 ml, then 0.8 to 1.0 ml / s, delayed 45 s). Images are standard algorithm reconstruction, respectively
