| Research Abstract |
Mouse fixation device for multi-modal imaging with no anesthesia was developed in this study. Fixation device was made with fixation plate using acrylic board and fixation folder using 50ml centrifuge tube. The changes of kinetics of glucose analogue tracer in in vivo with and without anesthesia were evaluated using fluorescent imaging (FLI) and positron emission tomography (PET) with this fixation device.
The uptake of the tracer in the brain measured with anesthesia was decreased in compared with non anesthesia and the decrease rate in FLI was higher than that in PET. It was thought that the reasons of it were the changes of cerebral blood flow and the differences of the tracers. It should be attention that a change may be occurred if the imaging device is changed for the imaging without anesthesia.
