Alzheimer's Disease: SPECT and PET Tracers for Beta-Amyloid Imaging
(2010)The definite diagnosis of Alzheimer's disease (AD) is based on the detection of beta amyloid (A beta) plaques and neurofibrillary tangles (NFTs) - which are the pathological hallmarks of the disease- in the postmortem ... -
BIOFUNCTIONALIZATION OF PET/SiO2 SURFACES FOR SINGLE MOLECULE EXPERIMENTS AND MEDICAL APPLICATIONS
(2011)PET/SiO2 layers were chemically modified to maintain immobilization of functional single molecules. GFP molecules provide an ideal system due to their stability and intrinsic fluorescence. GFP in vivo biotinylated within ... -
Comparison of three resistor network division circuits for the readout of 4 x 4 pixel SiPM arrays
(2013)The purpose of this study is to investigate the behavior of a flexible SensL's silicon photomultiplier array (SPMArray4) photodetector for possible applications in PET imaging. We have designed and evaluated three different ... -
Evaluation of a SiPM array coupled to a Gd3Al2Ga3O12: Ce (GAGG: Ce) discrete scintillator
(2015)Purpose: In this study, we present the results of the evaluation of the SensL ArraySL-4 photo-detector, coupled to a 6×6 GAGG:Ce scintillator array, with 2×2×5mm3 crystal size elements for possible applications in medical ... -
Imaging performance of silicon photomultipliers coupled to BGO and CsI: Na arrays
(2013)The aim of this study is to investigate the imaging performance of a silicon photomultiplier array (ArraySL-4) photodetector for possible PET and potentially SPECT applications using BGO and CsI(Na) pixellated scintillators. ... -
Initial results on SiPMs performance for use in medical imaging
(2011)Silicon photomultiplier (SiPMs) detectors are attractive candidates for replacing position sensitive photomultipliers in nuclear imaging. They are compact, they provide high gain with low bias voltage and show better ... -
Patient-specific internal radionuclide dosimetry
(2010)The development of patient-specific treatment planning systems is of outmost importance in the development of radionuclide dosimetry, taking into account that quantitative three-dimensional nuclear medical imaging can be ... -
A radionuclide dosimetry toolkit based on material-specific Monte Carlo dose kernels
(2009)Objective We sought to develop a user-friendly dosimetry toolkit that should aid the improvement of the quality of radionuclide therapy, which is critically dependent on patient-specific planning of each treatment. Methods ... -
A review of PET normalization: striving for count rate uniformity
(2013)The advent of PET instrumentation signaled the beginning of a new perspective in nuclear medicine diagnostic imaging. PET systems rely on several corrections that must be applied in order to establish accurate and reliable ... -
A Spartan3E-based low-cost system for gamma-ray detection in small single photon emission computed tomography or positron emission tomography systems
(2011)The development and assessment of a readout system based on field programmable gate arrays (FPGA) for dedicated nuclear medicine cameras is presented. We have used Xilinx Spartan3E starter kit, which is one of the simplest ... -
Temporal pole proton preoperative magnetic resonance spectroscopy in patients undergoing surgery for mesial temporal sclerosis
(2012)Object. The purpose of this prospective study was to compare the results of proton MR spectroscopy (MRS) in temporal poles in patients with unilateral mesial temporal sclerosis (MTS) with the histopathological findings of ...
