目的探讨低剂量螺旋CT扫描结合单层高分辨率CT（HRCT）在肺气肿CT（CTPE）诊断及肺癌筛查中的应用价值。在常规低剂量螺旋CT扫描的基础上，增加上肺野的单层HRCT扫描，以直观地发现低密度区（LAA）。根据左心耳在双侧上肺野的可见程度将受试者分为四组：无左心耳、轻度肺栓塞（0%）、轻度肺栓塞（0%）和轻度肺栓塞（0%）。
Object The present study was undertaken to evaluate the utility of low-dose spiral CT scanning, combined with single-slice high-resolution CT (HRCT), in the detection of pulmonary emphysema on CT (CTPE) together with screening for lung cancer.Subjects and Methods For 657 individuals who visited for screening of lung cancer, single-slice HRCT of the upper lung field was added on conventional low-dose spiral CT scanning in order to detect low attenuation area (LAA) visually. The individuals were classified into four groups according to the visual extent of LAA in bilateral upper lung fields: no LAA, subtle PE (0%
