【Abstract】 Objective To show the images of tracer-stretching along the acupuncture meridian by use of PET with multipurpose imaging tool (MPItool’s) fusion function. Methods On 5 healthy volunteers, we measured the classical acupuncture points accurately with the biophysical measuring method. 18 F-fluorodeoxyglucose (FDG) was injected into the selected points, the others points along the same meridian were labeled with 18 F-FDG applied on the correspondent skin area of <1 mm 2. With the same body position, the transmission image and emission image was acquired respectively and fused with MPItool and its 3D display system. Results We clearly showed not only the meridian-stretching images of the tracer, but also figured out the depth of the study points. The depth at SHANGJUXU point was about 3.8 cm and at ZUSANLI point was about 5.0 cm. The depthes basically fit the classically documented ones of the correspondent acupuncture points. Conclusions Using PET MPItool we preliminarily demonstrated that the tracer injected at the acupuncture point stretches along the correspondent meridian, and the depthes of the meridian and the points (SHANGJUXU, ZUSANLI) detected are almost accordant with the classically documented ones.更多还原
