摘要
目的:研究64排螺旋CT孤立性肺结节(SPN)重建血管支气管形态学改变与病理学相关性。探讨其临床诊断价值。方法:21例直径≤3cm的SPN患者(其中恶性结节14例,良性结节7例),行64排螺旋CT扫描,层厚为0.625mm,扫描后行动态CT增强扫描,层厚为2.5-5mm经GEAW4.2工作站多平面重组(MPR)、面重组(CPR)、表面遮盖显示(SSD)及VR重建,显示SPN与血管支气管形态特征的关系。结果:行64排螺旋CT扫描(骨算法)结合工作站各种后处理方法,能很好的显示SPN与相关血管支气管的形态特征及关系。结论:64排螺旋CT能清楚显示SPN与血管支气管形态特征及关系,两者对SPN良恶性性质的鉴别诊断有重要价值。
Objective:To investigate the bronchial and vascular appearance change of SPN in the reconstructed image and its correlation with pathology, and discuss its clinical significance in diagnosis. Methods: 21 patients with SPN (14 malignant and 7 benign) underwent CT scanning on 64 : slice scanner. All patients were scanned with breathe - holding position (0. 625 mm section thickness), followed by dynamic CT scanning (2.5 to 5mm section thickness). These images were reconstructed with MPR, CPR, SSD and VR in order to show the relationship of SPN with bronchial and vascular appearance. Results:Target scanning by 64 - slice CT combined with post - processed methods of workstation clearly showed the relationship of SPN with bronchial and vascular appearance. Conclusion:64 - slice CT can clearly show the relationship of SPN with bronchial and vascular appearance, which is important to differentiate malignant nodules with benign ones.
