| 内容記述 | The ability to make quantitative measurements of radioactivity is essential for human brain PET. Several attenuation correction methods have been reported for PET/MRI scanners, however, their influence on pixel intensity in reconstructed images has not yet been thoroughly evaluated. In this study, we evaluated the effect of these potential problems on human brain 18F-FDG-PET. The results indicate that pixel intensities on reconstructed images depend on the attenuation correction method used. Incorrect assignment of the attenuation coefficient for brain causes a larger error in the measured radioactivity than for bone and soft tissues. | |||||
