| 摘 要： | 目的探讨癌性肺不张的CT表现。方法回顾性分析经病理证实的150例癌性肺不张的CT表现。结果CT能够清晰显示支气管狭窄及阻塞，并能分清狭窄及阻塞的类型，诸如截断状梗阻、鼠尾状阻塞、局限性环行狭窄、锥形阻塞、偏心性狭窄、不规则狭窄、阻闭消失。强化后能够清晰显示肿块的镶嵌征、波浪征、“S”征、不均质强化、毛刺征。结论肿块影或支气管不规则狭窄及阻塞，是诊断癌性肺不张的可靠依据。

| Abstract: | Objective To study the CT findings of carcinous atelectasis.Methods CT findings of 150 patients with pathologically proved carcinous atelectasis were analyzed retrospectively.Results CT scans clearly revealed varied types of bronchial stenosis and obstruction such as interceptive-like obstruction,rat-tail-like obstruction,localized circular stenosis,tapered obstruction,eccentric stenosis,irregular stenosis,and obstruction disappear.After administration of contrast medium,CT scans clearly revealed tumoral mosaic sign,wave sign,"S"sign,non-homogeneous enhancement,and spiculated sign.Conclusion Mass shadow,bronchial stenosis and obstruction are reliable evidences for diagnosing carcinoid atelectasis. |
