术前了解肺癌在胸腔内的病变范围,对选择手术适应证的患者很重要.如已出现纵隔淋巴结转移,将不宜用根治性手术.CT 曾作为胸片后的首选放射诊断方法。具有高分辨率的磁共振成象(MRI)的出现,不但能多层次成象,又无离子辐射也不用静脉注射对比剂,故亦为选用的诊断方法.本文以胸片,CT 和MRI 对胸腔内病变范围的发现和判断能力加以比较.支气管癌患者46例,皆经痰检、经皮针吸活检、支气 Preoperative understanding of the extent of lung cancer lesions in the chest, is very important for patients with surgical indications. If there has been mediastinal lymph node metastasis, radical surgery will not be appropriate. CT has been used as the preferred method of radiological diagnosis after chest radiograph. The appearance of high-resolution magnetic resonance imaging (MRI) can not only achieve multi-level imaging, but also no ionizing radiation and no intravenous contrast agent, so it is also the diagnostic method used. This article uses chest radiograph, CT and MRI The ability to detect and determine the extent of lesions in the chest cavity was compared. 46 patients with bronchial carcinoma were treated with sputum examination, percutaneous needle biopsy, and bronchial
