作者复习362例疑肺癌而行CT检查的病例。CT用连续10mm准直切面,发现病灶后,在病灶区附加1.5mm准直切面。有弥漫钙化的结节诊断为肯定良性;2cm或以下边缘光滑的结节,以及伴有卫星病灶或局限实变区的结节考虑为可能良性;无钙化的弧立结节伴边缘毛刺或直径超过2cm者考虑为符 The author reviewed 362 cases of suspected lung cancer who underwent CT examination. A continuous 10mm collimation section was used for CT. After the lesion was found, a 1.5mm collimation section was added to the lesion area. Diagnosis of diffuse calcified nodules was positive for benign; nodules with smooth edges of 2 cm or less, and nodules with satellite lesions or confined consolidations were considered as potentially benign; calcified nodular nodules with marginal burrs or diameters Over 2cm is considered as a character
