目的:探讨三维重建图像对孤立性肺结节(SPN)血管集束征的显示及其诊断价值。资料与方法:回顾性分析经病理确诊的63例SPN,在三维重建工作站进行多平面重组(MPR)及容积再现(VR),观察血管集束征的显示,统计分析两种方法的差异以及在良恶性SPN鉴别诊断中的应用价值。结果:SPN的血管集束征在VR图像显示率高于MPR(P<0.05),在MPR和VR图像上,恶性SPN血管集束征的显示率均高于良性(P<0.05)。结论:三维重建图像能够更全面地显示血管集束征,对SPN的良恶性分析有一定的参考价值。
OBJECTIVE: To investigate the diagnostic value of three-dimensional reconstructed images in the clustering of solitary pulmonary nodules (SPNs). Materials and Methods: Retrospective analysis of 63 cases of pathologically diagnosed SPN, three-dimensional reconstruction workstation for multiplanar reorganization (MPR) and volume rendering (VR), to observe the collection of signs of vascular bundles, statistical analysis of the differences between the two methods and good The value of malignant SPN in the differential diagnosis. Results: The clustering of SPN in VR images was higher than that of MPR (P <0.05). In both MPR and VR images, the signs of clustering of malignant SPN were higher than that of benign ones (P <0.05). Conclusion: Three-dimensional reconstruction images can show vascular bundles more fully, and have certain reference value for the analysis of benign and malignant SPN.
