Abstract

The purpose of this research is to compare and analyze SUVLBM-maximum of normal regions using VOI (the volume of interest) in order to enhance the diagnostic level in whole body images of PET/CT and PET/MRI for 26 health check-up participants. In particular, we try to set up SUVLBM-maximum data that can be used in synchronous evaluation for PET/CT and PET/MRI without contrast media. The evaluation of SUVLBM-maximum for normal regions of whole body PET/CT and whole body PET/MRI shows that the image of PET/MRI differs very significantly from the reference image of PET/CT (p＜0.0001). However, they exhibit high correlations in view of statistics (R＞0.8). From this research, we suggest that the decision in the evaluation of SUVLBMmaximum for PET/MRI should be made with the reduction of about 26.3%, while one should decide with the reduction of about 29.3% when the contrast media is used. It is helpful to interpret all image of PET/CT and PET/MRI using SUVLBM-maximum for convenience and efficiency.
