Up to 4 SPECT/CT scans can be loaded simultaneously for comparison purposes. Neste vídeo falamos das principais diferenças entre PET e SPECT equipamentos utilizados na Medicina NuclearO PET é a Tomografia por Emissão de Pósitron e o S 2020-05-01 · PET Versus SPECT. PET imaging is generally considered superior to SPECT due to accurate attenuation correction, higher spatial resolution, lower radiation dose, faster imaging times, and ability to perform dynamic imaging for MBF quantification. For this reason, development of new PET tracers has been accelerating within the past decade.

Methods: Twenty-six patients with probable AD (mean age phy (PET) or Single Photon Emission Computed Tomography (SPECT) are non-invasive, in-vivo, functional, molecular imaging technologies that have shown promise for speciﬁc identiﬁcation of cancer due to their unique ability Radionuclide-based imaging (PET and SPECT) have properties that allow us to do so efficiently, mostly due to their high sensitivity, imaging signal tissue penetration, and accurate quantification. Furthermore, they can be easily translated from animals to humans.

En contraste con PET, los marcadores usados en SPECT emiten radiación gamma que se puede medir directamente, mientras que los marcadores de PET emiten positrones que se aniquilan con electrones que tienen a unos milímetros, produciendo dos fotones gamma que se emiten en direcciones opuestas. AnyScan-familjen är Medisos SPECT- och PET-serie och kan kombineras med CT. AnyScan Trio är den enda produkten på marknaden som har tre huvuden. AnyScan Trio SPECT kan fås med flerhålskollimatorer med utbytbar apertur för Alzheimer, Parkinson och kardiologi. AnyScan-serien går att konfigurera med ett, två eller tre huvuden.

Virtual PET Scanner – From Simulation in GATE to a Final Multiring Albira PET/ SPECT/CT Camera. By M. Balcerzyk, L. Caballero, C. Correcher, A. Gonzalez,

While SPECT scans measure gamma rays, the decay of the radiotracers used with PET scans produce small particles called positrons. SPECT versus PET • PET delivers absolute activity, but appropriate radionuclides with multiple-day half lives are hard to find. • SPECT probably needs at least attenuation correction. This correction, in turn, probably requires a multi-modality (PSPECT/CT) imager or SPECT-CT registration.

SPECT (and PET) provide the only non-invasive technique for imaging brain neurochemicals. The longer SPECT half -life Hexamethylpropyleneamine oxime (HMPAO) SPECT and 18F-FDG PET depict similar aspects of perfusion and metabolic abnormalities in Alzheimer’s disease (AD), but the correspondence between them is not known in detail. We therefore used statistical parametric mapping to detect and compare abnormal brain areas objectively and quantitatively.

For basic research, PET is the more flexible tool, because innovative tracers are more easily synthesised for PET than for SPECT. In addition, the spatial resolution of PET is better than that of SPECT - far better. This is due to the physical nature of nuclear decay of positrons.

More recently, positron emission tomography (PET) has been applied to the study of the heart and its uses continue to expand. PET Scans (Positron Emission Tomography) and SPECT Scans (Single Photon Emission Computed Tomography) were first used in the 1970's for research. Now, some 30 years later, these non-invasive techniques have been adapted to diagnose disease in humans. Many physicians in fields including cardiology, neurology, and oncology use PET Scanning.
