目的 研究多层螺旋CT (MSCT)不同三维重建方法在孤立性肺结节(SPN)的应用价值。方法 32例孤立性肺结节患者,均行MSCT平扫及增强扫描,分别以MPR、SSD、MIP、Min-IP等技术进行重建,观察四种重建方法对结节的边缘形态、内部结构、灶周血管、灶周支气管及邻近胸膜改变等的显示,并评分比较。结果 四种重建方法显示病变各有优点。MPR可从多平面多角度显示病变;SSD可以立体显示结节及其周围的改变,以显示胸膜改变效果最佳;MIP在显示灶周血管病变上优于其他方法;Min-IP显示外周支气管效果欠佳。结论 MSCT三维重建图像可直观显示病变,有利于全面观察孤立性肺结节,结合横断面可对病变作出较完善的评价。 |

Objective To discuss the three-dimensional (3D) reconstruction techniques of multi-slice spiral CT (MSCT) and its clinical application value in solitary pulmonary nodule (SPN). Methods MSCT routine and enhanced scanning were performed in 32 patients with SPN, and 3D reconstruction was made using MPR, SSD, MIP and Min-IP. Their visualization capabilities of SPN (including internal architecture, surface features and the adjacent structures such as bronchi, vessels and pleura) were analyzed and compared. Results The four post-processing techniques had respective advantages in appearing the lesions. MPR displayed the lesions from different angle, SSD was good at displaying the adjacent pleura, while MIP was better than other techniques in displaying the adjacent vessels, and Min-IP was not good at display of peripheral bronchi. Conclusion MSCT can make good axial and processed images that clearly display the lesions and make them wholly apprehended. Combination of the axial and post-processing images can be helpful to evaluate the lesion perfectly. |
