Introduction: The positron emission tomography (PET) problem with Poisson log-likelihood is notoriously ill-conditioned. This stems from its dependence on the inverse of the measured counts and the square of the attenuati...
First positronium lifetime imaging with scandium-44 on a long axial field-of-view PET/CT [0.03%]

Purpose: The physical properties of 44Sc, combined with its imminent clinical application, position it as a prime candidate for in vivo positronium lifetime imaging. In this study, we investigate the count statistics for ...
Case Report: 18F-Fluorocholine PET/CT for detecting brown tumours in patients with hyperparathyroidism: a short case series and literature review [0.03%]

Introduction: Brown tumours (BTs), also known as osteitis fibrosa cystica, are benign osteolytic lesions associated with hyperparathyroidism (HPT). BTs are cured by correcting the hypercalcaemia and HPT, which often requi...

PET/CT imaging of bone disorders in dysparathyroidism: a comprehensive review [0.03%]
特发性甲状旁腺功能紊乱骨病的正电子发射断层扫描/计算机体层摄影检查：系统综述

E Panagiotidis et al.
Parathyroid disorders profoundly affect bone metabolism, often long before structural damage is apparent on conventional imaging. Positron emission tomography/computed tomography (PET/CT) has emerged as a transformative tool in dysparathyro...
Production of 64Cu and 67Cu with accelerator neutrons by deuterons and their separation from zinc [0.03%]
加速中子生产64Cu和67Cu并从锌中分离它们

Yasuki Nagai et al.
The 64Cu/67Cu pair is an ideal set of theranostic radionuclides for treating patients based on their genetic profiles. We propose a novel production route for this radionuclide pair using accelerator-generated neutrons. We report experiment...

Population pharmacokinetic (PopPK) has emerged as a robust framework for characterizing inter-individual variability in the absorbed dose estimates in radiopharmaceutical therapy (RPT). By enabling the analysis of biokinetic data from heter...
Fast PET reconstruction with variance reduction and prior-aware preconditioning [0.03%]
一种基于降方差和先验预处理的快速PET重建方法

Matthias J Ehrhardt
We investigated subset-based optimization methods for positron emission tomography (PET) image reconstruction incorporating a regularizing prior. PET reconstruction methods that use a prior, such as the relative difference prior (RDP), are ...
Platinum group metals for nuclear medicine, a luxurious dream or the future of imaging and therapy: a review [0.03%]
