| 目的 探讨64层螺旋CT对先天性血管环的诊断价值。方法 回顾性分析32例先天性血管环患者的CT资料,并进行多平面重组(MPR)、最大密度投影(MIP)、最小密度投影(MinIP)、容积再现(VR)及图像融合技术,评价图像质量能否满足诊断要求以及图像重组的可行性。结果 32例患者的扫描图像均能够进行三维重组,重组图像能够很好地显示心血管解剖。MPR、VR重建图像直观显示血管环的组成及空间关系,MinIP及气管VR重建图像清晰显示气道形态及发育状况,图像融合技术可直观显示血管环与气管、食管的空间关系。结论 64层螺旋CT轴位扫描结合多种三维重建后处理技术可直观、清晰显示血管环的组成及与气管、食管间的毗邻关系,是检查血管环的有效手段。 |

| Objective To investigate the application value of 64-sclie CT in the diagnosis of congenital vascular rings. Methods CT images of 32 patients with congenital vascular rings were analyzed retrospectively, and the images were reconstructed with multiplanar reconstruction (MPR), maximum intensity projection (MIP), minimum intensity projection (MinIP), volume rendering (VR) and image fusion. The quality of reconstruction image and the feasibility of reconstructing were evaluated. Results All vascular rings and other morphologies in 32 patients were displayed through 3D reformatting, and the processing was fluent and efficient. The quality of images was competent for diagnosis. MPR and VR displayed spatial relation and construction of vascular rings definitely, MinIP and air-VR discovered morphous and growth of trachea easily, and image fusion technique visualized spatial relation between vascular rings and trachea or esophagus. Conclusion 64-slice spiral CT allows for accurate and comprehensive display of the vessels, trachea with main bronchi and esophagus in vascular rings patients. |
