| 目的 探索基于磁共振成像的肝脏脉管(血管、胆管)三维重建的方法,以显示肝脏中血管、胆管走行立体图像,从而指导劈离式肝脏移植手术。方法 综合利用二维图像的多种平滑和分割方法,得到肝实质和肝脉管二维图像序列,并在此基础上三维重建肝实质和肝脉管。结果 由MR图像序列可三维重建清晰的肝实质和肝血管立体图像,并且可得到肝叶、段间血管及胆管的走行及相互关系。结论 利用MRI和图像分割以及图像三维重建技术指导劈离式肝移植手术,具有重要的临床意义。 |

| Objective To explore the Methods for 3-dimensional reconstruction of the liver vessels including blood vessel and bile duct based on the MR images for guiding the split-liver transplantation. Methods The 2-dimensional MR image series of liver parenchyma and liver vessels were obtained by utilizing various image processing Methods including smoothing, segmentation and then the final 3-dimensional images were obtained from the image series by using a 3-dimensional reconstruction algorithm. Results The final 3-dimensional images of liver parenchyma and liver vessels reconstructed from the MR image series were very clear and the 3-dimensional spatial structure of the blood vessel and bile duct could be shown clearly. Conclusion It is very useful to use MRI, image segmentation and 3-dimensional reconstruction techniques to guide the split-liver transplantation surgery. |
