体内18F-DG循经迁移线的三维断层及透视观察陈英茂 田嘉禾 何义杰 张锦明 邵明哲 祝总骧 徐瑞民


  [摘 要] 目的:实现示踪剂循经迁移线的三维断层及透视观察。方法:志愿者下巨虚穴位点注18f-fdg,pet采集腿部透射及发射图像,对透射及发射图像进行融合并重建融合后的透视图。结果:融合后的三维断层图,实现了循经迁移线的空间定位显示,但无法看到完整的循经迁移线,只是断续线段;重建的透视图实现了从各个方向直观观察完整循经迁移线及其在体内走行位置,并可立体旋转显示。结论:图像融合后的透视图实现了循经迁移线的立体透视显示。

  [abstract] purpose to realize investigation on three dimensional (3d)

tomogram and scenograph of the migration line of tracer along meridians. methods 18fdg(2-[18f]fluoro-2-deoxy-β-d-glucose) was injected

into point xiajuxu (st 39) in the volunteer. with the stable body position, three

transmission and emission images were respectively acquired, then the

transmission and emission images were reconstructed and fused together. based

on the fusion images, the scenographs of the migration lines were reconstructed.

results the fusion of the 3d transmission and emission images could locate

migration lines along meridians in the body. but whole migration line along the

meridian could not be shown on a slice of tomogram, only some intermittent

segments could be displayed. the scenographs based on fusion images made it

possible to directly observe the whole meridian line in every direction.

conclusion 3d scenograph of the migration line along the meridian based on 3d

imaging fusion is a better way in location of the migration line along the

meridian in the body.

  [key words] meridian/radionuclide; meridian phenomenon; meridian line

detection; tomography; emission-computed, single-photon

  经络是祖国传统医学的重要组成部分,多年来,对经络实质的研究一直是个热门课题,但由于经络现象的复杂性,学术界多年来缺少客观显示和检测的技术方法。
