Abstract. Over the last decade multimodality devices have revolutionized the domain of medical imaging. The first example is PET/CT which has already become a gold standard in oncology imaging. The next chapter in multimodality imaging and associated integration concerns the development of PET/MRI devices, offering clear advantages for brain imaging relative to PET/CT. Despite the obvious...

39. Partial volume effect (PVE) issue: instrumental and biological components

Dr I. Buvat

Abstract. In the continuing efforts towards accurate quantification in PET and SPECT, partial volume effect (PVE) remains an extremely challenging issue. PVE is not only caused by the limited spatial resolution in PET and SPECT images, but also by the unavoidable sampling of the images into matrices of voxels. PVE results in biased measurements, with bias depending on many factors related not...
