Dual Prompting for Diverse Count-level PET Denoising

Xiaofeng Liu, Yongsong Huang, Thibault Marin +6

The to-be-denoised positron emission tomography (PET) volumes are inherent with diverse count levels, which imposes challenges for a unified model to tackle varied cases. In this w…

On hallucinations in AI-generated content for nuclear medicine imaging (the DREAM report)

Menghua Xia, Reimund Bayerlein, Yanis Chemli +7

Artificial intelligence-generated content (AIGC) has shown remarkable performance in nuclear medicine imaging (NMI), offering cost-effective software solutions for tasks such as im…

Unsupervised Adaptation from FDG to PSMA PET/CT for 3D Lesion Detection under Label Shift

Xiaofeng Liu, Menghua Xia, Yanis Chemli +3

In this work, we propose an unsupervised domain adaptation (UDA) framework for 3D volumetric lesion detection that adapts a detector trained on labeled FDG PET/CT to unlabeled PSMA…

PET mapping of receptor occupancy using joint direct parametric reconstruction

Thibault Marin, Vasily Belov, Yanis Chemli +8

Receptor occupancy (RO) studies using PET neuroimaging play a critical role in the development of drugs targeting the central nervous system (CNS). The conventional approach to est…

Motion correction for PET using subspace-based real-time MR imaging in simultaneous PET/MR

Thibault Marin, Yanis Djebra, Paul K. Han +6

Image quality of PET reconstructions is degraded by subject motion occurring during the acquisition. MR-based motion correction approaches have been studied for PET/MR scanners and…
