We found some signs are of great importance:opaque glass sign,alveolar nodular sign,pathologic air bronchogram sign.

磨砂玻璃征,结节,病理性支气气相具有重要的诊断值。

Calcification, air-bronchogram, cavity and pleural indentation of the lesion in the peripheral lung cancer were better displayed by spiral than by conventional CT.

螺旋CT扫描对病灶内钙化、、气支气、及病灶局部胸膜凹陷等征象均优于常规CT。
