摘要
目的:探讨双源CT增强扫描在判断中央型肺癌对气管、支气管树及纵隔/肺门大血管侵犯中的价值。材料与方法:92例中央型肺癌患者术前均行双源CT增强扫描,通过多种后处理技术分析气管、支气管树及纵隔/肺门大血管侵犯情况,并与手术/病理结果进行对照。结果:1共分析气管、支气管201支,DSCT诊断阳性149支,表现为管壁受压增厚、管腔轻度不规则56支(37.6%,其中有8支高估),管壁增厚、管腔狭窄71支(47.7%),管腔截断/闭塞22支(14.7%);DSCT诊断阴性52支(其中14支低估)。2共分析血管209支,DSCT诊断阳性120支,表现为血管壁轻度不规则17支(14.2%,其中9支高估),血管腔明显狭窄甚至闭塞93支(77.5%),血管腔瘤栓形成、充盈缺损10支(8.3%);DSCT诊断阴性89支(其中10支低估)。结论:双源CT增强扫描多种后处理技术可准确评价肺癌周围侵犯程度,对判断中央型肺癌侵犯气管、支气管及纵隔/肺门血管有重要价值,有助于胸外科医师制定恰当的治疗方案。
Purpose： To investigate the value of enhanced dual-source CT（ DSCT） scan in the diagnosis of the tracheobronchial tree and the central pulmonary vascular involvement from central type of lung cancer（ CLC）. Materials and Methods： Ninety-two cases of patients with CLC were underwent enhanced DSCT scan,tracheobronchial tree and the central pulmonary vascular involvement from the neoplasm were studied through processing techniques. Results： 1 Altogether 201 tracheobronchial tree were analyses,DSCT positive findings in 147 bronchus,which were showed as compression and / or thickening of bronchial wall,mild irregular lumen（ n = 56,37. 6%,eight of which were overvalued）,thickening of bronchial wall and stenosis of lumen（ n = 71,47. 7%）,truncate or obliteration of lumen（ n = 22,14. 7%）. DSCT Negative findings in 52bronchus（ fourteen of which were undervalued）. 2Altogether 209 central pulmonary vascular were analyses,DSCT positive findings in 120 vascular,which were showed as mild irregular vascular wall（ n = 17,14. 2%,nine of which were overvalued）,obvious narrowing or obliteration of lumen（ n = 93,77. 5%）,tumor thrombosis and filling defect of lumen（ n = 10,8. 3%）. DSCT negative findings in 89 vascular（ ten of which were undervalued）. Conclusion： The invasion of surrounding of lung cancer could be accurately assessed on enhanced DSCT with post-processing techniques,which provides significant information in judging whether there are tracheobronchial tree and the central pulmonary vascular invasion by CLC.
