| 摘 要： | 目的探讨VR法MSCT门静脉三维成像技术的临床应用价值。方法门静脉正常者和异常者各30例,用容积再现和最大密度投影两种方法进行多层螺旋CT门静脉成像,对所得图像进行分析比较。结果容积再现法能满意显示正常和异常的门静脉,有良好的空间分辨力;最大密度投影法对显示门静脉细小分支有优势。结论MSCT容积再现法是门静脉三维成像中快捷而精确的技术,具有广阔的临床应用前景。

| Abstract: | Objective:To evaluate the clinical value of the technique of multi-slice CT portography with three-dimensional volume rendering method.Methods:30 people of with normal portal veins and 30 patients with abnormal portal veins were scanned by multi-slice spiral CT and their portal veins were reconstructed with VR and MIP.The effects of images were compared and analysed respectively.Results:VR could display normal and abnormal portal veins satisfactorily with superior capability of space resolution.And MIP had superiority just in the aspect of displaying fine branches of portal vein.Conclusion:Of the 3D imaging methods for portal vein,VR is a swift and accurate one that can be expected to use widely in clinic application. |
