Improving the Quality of Brain PET Images Using MR‐Guided PET Reconstruction Technique With Integrated PET/MR

open access: yesHuman Brain Mapping, Volume 46, Issue 11, 01 August 2025.
The PET list‐mode data was processed with OSEM algorithm and MR‐guided reconstruction (MRg) based on T1‐weighted MR images (TIWI). Several quantitative parameters were calculated to compare the image quality for conventional OSEM, OSEM_GF, and MRg reconstructions with varying parameters (θ = 0.5, 1, 2).
