A new system enables multiparametric scans for investigating rodent models of diseases and cross-validation studies of bimodal imaging probes.
Positron emission tomography (PET) scanners provide quantitative information about various physiological and biochemical processes that occur in a living body (e.g., glucose metabolism, gene expression, and drug occupancy). In general, scintillation detectors—consisting of inorganic scintillation crystal and photosensor arrays—are used in PET scanners to measure the gamma rays that are emitted from radiopharmaceuticals. In this process, visible or UV photons are emitted when gamma rays are detected by the scintillation crystal and are then measured by the photosensors. There are, however, several problems associated with these traditional PET detection systems (e.g., limited efficiency and high cost) and alternative options are therefore required. Read more.
