Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.

PET and SPECT Single photon emission computed tomography (SPECT) imaging is routinely used and is the primary functional imaging tool used to evaluate the heart. More recently, positron emission tomography (PET) has been applied to the study of the heart and its uses continue to expand.

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.

PET-kameraundersökning. PET-kameraundersökning används för att läkaren ska få mer kunskap om något som upptäckts vid en tidigare undersökning. Det kan till exempel vara att ta reda på om en misstänkt tumör är cancer eller inte. Vid undersökningen får du ligga på en brits som åker in i en kamera, som liknar en stor ring. Positronemissiontomografi (PET) är en medicinsk avbildningsteknik som bygger på användningen av radioaktivt märkta molekyler. Med dessa kan man exempelvis följa ämnesomsättningen i ett organ eller följa hur olika substanser rör sig i kroppen. PET ger sämre upplösning än MR men är bättre på att följa molekylära skeenden och funktion.

Det finns faktiskt två typer av SPECT-kameror; en som på enkel svenska kallas för Förkortningen PET står för Positron Emission Tomography.

16 Aug 2017 In this study, PET yielded the highest overall diagnostic accuracy, which was greater than CTA or SPECT. Of course, given the physiologic end

その他の違いは以下のとおり。. PETは、空間分解能が高い、感度も高い（血流の他、糖代謝なども検査 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 PET scans also use radiopharmaceuticals to create three-dimensional images. The main difference between SPECT and PET scans is the type of radiotracers used. While SPECT scans measure gamma rays, the decay of the radiotracers used with PET scans produce small particles called positrons.

This is due to the physical nature of nuclear decay of positrons. This Review provides an overview of selected molecular-based single photon emission CT (SPECT) and PET imaging strategies for the evaluation of cardiovascular disease—including the evaluation of PET and SPECT Single photon emission computed tomography (SPECT) imaging is routinely used and is the primary functional imaging tool used to evaluate the heart. More recently, positron emission tomography (PET) has been applied to the study of the heart and its uses continue to expand. 2020-12-01 Background: PET and SPECT imaging methods can be of excellent assistance for the development of new nanoparticle drug delivery systems, and at the same time, these investigations also offer the opportunity to produce exceptional new diagnostic and therapeutic radiopharmaceuticals, as well. 2020-12-01 Positron emission tomography (PET)-magnetic resonance (MR) or single photon emission computed tomography (SPECT)-MR hybrid imaging is being used in daily clinical practice. Due to its advantages over stand-alone PET, SPECT or MR imaging, in many areas such as oncology, the demand for hybrid imaging techniques is increasing dramatically.

SPECT is an imaging technique similar to PET that uses radioligands to detect molecules in the body. SPECT is less expensive and provides inferior image quality than PET.

This correction, in turn, probably requires a multi-modality (PSPECT/CT) imager or SPECT-CT registration.
