目的探讨多层螺旋CT及重建技术对气管主支气管肿瘤的诊断价值。方法 20例气管主支气管肿瘤患者,所有患者均经手术病理证实为原发性气管主支气管肿瘤。对患者的多层螺旋CT检查结果进行回顾性分析,在AW工作站,应用多平面重建(MPVR)、肺透明化重建(VR)和仿真内窥镜(CTVE)软件对图像重建数据行后处理重建,分别得到MPVR、VR和CTVE图像,将结果与手术病理结果进行对照分析。结果良性肿瘤2例,恶性肿瘤18例,11例分布在气管,4例分布在左主支气管,5例分布在右主支气管;管腔内窄基底结节6例,管腔内宽基底结节14例;生长不规则11例,成环状生长3例,偏心生长6例;6例向管腔内突出未向外浸润,4例轻度向外浸润,10例向外浸润并与相邻结构粘连;平滑肌肉瘤密度均匀,中度强化,脂肪瘤为低密度影,不强化,恶性肿瘤密度不均匀,强化不均匀。结论多层螺旋CT及重建技术能够对气管主支气管肿瘤做出准确的诊断并帮助制定手术方案,具有重要的临床意义。
Objective To investigate the diagnostic value of multi-slice spiral CT and reconstruction techniques for tracheobronchial tumors. Methods Twenty patients with tracheobronchial tumors were enrolled. All patients were proved to be primary tracheobronchial tumors by surgery and pathology. The results of multi-slice spiral CT examination were analyzed retrospectively. The AW reconstruction workstation was used to reconstruct the reconstructed image data by MPVR, , Respectively MPVR, VR and CTVE images, the results and surgical pathology results were analyzed. Results There were 2 cases of benign tumor, 18 cases of malignant tumor, 11 cases of trachea, 4 cases of left main bronchus, 5 cases of right main bronchus, 6 cases of narrow basal nodules in the lumen, 14 cases; irregular growth in 11 cases, ring growth in 3 cases, eccentric growth in 6 cases; 6 cases to the lumen without outward infiltration, 4 cases of mild outward infiltration, 10 cases of infiltration and adjacent Structural adhesion; smooth muscle sarcoma density, moderate enhancement, lipoma is a low density, not enhanced, malignant tumor density uneven, uneven reinforcement. Conclusion Multi-slice spiral CT and reconstruction techniques can make accurate diagnosis of tracheal bronchogenic tumors and help to develop surgical plans, which has important clinical significance.
