Anatomically guided voxel-based partial volume effect correction in brain PET: impact of MRI segmentation
D Gutierrez, ML Montandon, F Assal, M Allaoua… - … Medical Imaging and …, 2012 - Elsevier
Partial volume effect is still considered one of the main limitations in brain PET imaging
given the limited spatial resolution of current generation PET scanners. The accuracy of
anatomically guided partial volume effect correction (PVC) algorithms in brain PET is largely
dependent on the performance of MRI segmentation algorithms partitioning the brain into its
main classes, namely gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF). A
comparative evaluation of four brain MRI segmentation algorithms bundled in the …
