| 摘 要： | 目的:探讨CT仿真内窥镜(CTVB)及网格显示模式(mesh display mode,MDD)在中央型肺癌诊断中的应用。方法:对10例经临床、病理证实的中央型肺癌患者行CTVB及MDD重建检查,包括鳞癌6例、腺癌2例、小细胞癌1例、大细胞癌1例。用螺旋CT机对患者进行扫描后,将数据重建成CTVB及MDD图像进行分析。结果:10例中CTVB及MDD显示肿瘤呈块状或结节状,引起管腔狭窄或闭塞。其中MDD显示支气管狭窄9支、闭塞4支,尤其是观察支气管肿瘤腔外侵犯的移行情况优于CTVB图像。但MDD显示支气管腔内瘤体则逊于CTVB图像。结论:CTVB及MDD是一种无创伤的诊断方法,但其敏感性和特异性有待今后进一步研究提高。

| Abstract: | Objective: To discuss the clinical application of CT virtual bronchoscopy(CTVB) and mesh display mode(MDD) in the diagnosis of central lung cancer. Methods: Ten cases confirmed by pathology underwent volume scanning using spiral CT. The patients examined included 6 cases of squamous cell carcinoma, 2 cases of adenocarcinoma, 1 case of small cell carcinoma, and 1 case of large cell carcinoma. Data were transferred to computer workstation, then CTVB and MDD images with pseudocolor encoding were generated using Navigator Smooth soft-ware. Results: CTVB and MDD images in 10 cases could demonstrate the tumor which appeared as masses or nodules causing bronchial wall thickening and occlusion. In these cases, the MDD image which displays 9 narrowing bronchial lumens and 4 occlusions is superior to CTVB, especially in observing the invasive consequences of bronchial extraluminal tumor. However, MDD is inferior to CTVB images in showing intraluminal masses. Conclusion: Both CTVB and MDD are noninvasive methods for observing the airway. While, the sensitivity and specificity of CTVB and MDD for lesion detection still require further improvement. |
