摘要
目的评价X线、CT、MRI、DSA对周围型肺癌的诊断价值。方法分析58例经病理证实的周围型肺癌的X线正侧位胸片、CT、MRI及DSA片。结果X线片、CT对显示钙化和肋骨受侵情况较MRI好;CT对显示周围型肺癌的边缘有无毛刺分叶切迹、棘状突起较MRI好;MRI对周围型肺癌不能显示空泡征及支气管充气征;CT、MRI对空洞、液化坏死及胸膜凹陷征较X线平片高。结论CT是周围型肺癌检查的首选方法,X线胸片是不可缺少的基础,MRI可作为参考补充,而DSA是周围型肺癌诊断与治疗的最好方法。
Objective To evaluate the value of X- ray, CT, MRI, and DSA in diagnosing peripheral pulmonary carcinoma by comparing the characters of the four methods. Methods 58 patients with peripheral pulmonary carcinoma, all ascertained by pathologic evidence finally, accepted chest X- ray, CT, MRI and DSA examinations, the data was analyzed. Results X - ray and CT were clearer to show calcification and rib invasion ; CT was prominent in showing the existence of prickle, sign of lobulation, indentation, and acanthoid protuberance around the lesion border of peripheral pulmonary carcinoma, Vacuolar sign and bronchi alr- sigh in peripheral pulmonary carcinoma could not be revealed with MRI in all patients. CT and MRI showed better in finding cavity and pleura pitting than chest X - ray. Conclusion CT should be the first choice in examining and researching peripheral pulmonary carcinoma; Chest X- ray is a essential method; MRI could be a supplementary means. DSA is the best approach in diagnosing peripheral pulmonary carcinoma.
