中央气道的异常通常引起明显的临床症状,在胸片上却往往无明显的表现而造成漏诊或误诊。如进一步行CT检查,尤其是螺旋CT及三维重组,对发现病变、准确描述病变位置、范围及制定外科治疗计划尤其有用。综述了中央气道病变的CT检查技术及其局灶性和弥漫性疾病的CT诊断。 Abnormalities of the central airways usually cause significant clinical symptoms, but there is often no apparent manifestation on the chest radiograph resulting in misdiagnosis or misdiagnosis. Such as further CT examination, especially spiral CT and three-dimensional reconstruction, the discovery of lesions, accurately describe the location of the lesion, surgical planning and planning is particularly useful. The CT examination of central airway lesions and CT diagnosis of focal and diffuse diseases were reviewed.
