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.
