NEMA NU 4-2008 Comparison of Preclinical PET Imaging Systems
TLDR
Variation in system design makes direct comparisons between systems from different vendors difficult, and when considering the results from NEMA testing, one must also consider the suitability of the PET system for the specific imaging task at hand.
Properties of LYSO and recent LSO scintillators for phoswich PET detectors
The luminescence and nuclear spectroscopic properties of the new cerium-doped rare-earth scintillator lutetium-yttrium oxyorthosilicate (Lu/sub 0.6/Y/sub 1.4/Si/sub 0.5/:Ce, LYSO) were investigated

TLDR
Novel imaging combinations are being considered that would enable simultaneous, or at least concurrent, dual-modality imaging through combined PET/MR or PET/CT, and the development of these new integrated instruments creates new bewildering challenges for PET detection systems, which must satisfy several other critical requirements.
In vivo measurement of energy substrate contribution to cold‐induced brown adipose tissue thermogenesis
TLDR
The cold‐induced increase in oxidative activity was meaningfully blunted by nicotinic acid, a lipolysis inhibitor, which emphasizes in vivo the key role of intracellular lipid in BAT thermogenesis.
Geometry Study of a High Resolution PET Detection System Using Small Detectors
The current trend in positron emission tomography (PET) towards very high spatial resolution tomographs raises the problem of detecting high energy gamma-rays with a high spatial accuracy while
Image-derived input function in dynamic human PET/CT: methodology and validation with 11C-acetate and 18F-fluorothioheptadecanoic acid in muscle and 18F-fluorodeoxyglucose in brain
TLDR
Correctly obtained, carotid and femoral artery IDIFs can be used as a substitute for AIFs to perform tracer kinetic modelling in skeletal femoral muscles and brain analyses.
Respiratory gating for 3-dimensional PET of the thorax: feasibility and initial results.
TLDR
Respiratory gating of PET of the thorax and upper abdomen is a practical and feasible approach that may improve the detection of small pulmonary nodules and prospectively the diagnostic accuracy of this new method is planned.
Performance evaluation of the LabPET™ APD-based digital PET scanner
TLDR
The LabPETTM is a fully digital avalanche photodiode (APD) based PET scanner designed for state-of-the- art molecular and genomic imaging of small animals and demonstrated with in vivo images of rats and mice.
Small-Animal PET: What Is It, and Why Do We Need It?*
TLDR
The operational and technical aspects of small-animal PET are discussed; some comparisons between small-Animal PET and human PET systems are made; identify the challenges of, opportunities for, and ultimate limitations in applying small- animal PET; and discuss some representative small- Animal PET applications.
