Journal ArticleDOI
Initial results from the Sherbrooke avalanche photodiode positron tomograph
Roger Lecomte,Jules Cadorette,S. Rodrigue,D. Lapointe,D. Rouleau,M. Bentourkia,Rutao Yao,P. Msaki +7 more
TL;DR: In this paper, the Sherbrooke APD-PET scanner has been evaluated in terms of resolution, sensitivity, count rate, random and scatter fractions, contrast and relative activity recovery as a function of object size.
Journal Article
Respiratory Gating for 3-Dimensional PET of the Thorax: Feasibility and Initial Results
TL;DR: 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.
Journal ArticleDOI
NEMA NU 4-2008 Comparison of Preclinical PET Imaging Systems
Andrew L. Goertzen,Qinan Bao,Melanie Bergeron,Eric Blankemeyer,Stephan Blinder,M. Canadas,Arion F. Chatziioannou,Katherine Dinelle,Esmat Elhami,Esmat Elhami,Hans Sonke Jans,Eduardo Lage,Roger Lecomte,Vesna Sossi,Suleman Surti,Yuan-Chuan Tai,Juan José Vaquero,Esther Vicente,Darin Williams,Richard Laforest +19 more
TL;DR: 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.
Journal ArticleDOI
Properties of LYSO and recent LSO scintillators for phoswich PET detectors
C.M. Pepin,P. Berard,A. Perrot,Catherine M. Pepin,D. Houde,Roger Lecomte,Charles L. Melcher,Henri Dautet +7 more
TL;DR: In this paper, 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 and compared to those of both recent and older LSO crystals.
Journal ArticleDOI
In vivo measurement of energy substrate contribution to cold-induced brown adipose tissue thermogenesis
Sébastien M. Labbé,Alexandre Caron,Inan Bakan,Mathieu Laplante,André C. Carpentier,Roger Lecomte,Denis Richard +6 more
TL;DR: 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.
