PET-kameraundersökning är en metod som används för att undersöka olika organ i kroppen, bedöma sjukdomstillstånd eller följa effekterna av en behandling.

SPECT radionuclides generally have longer half-lives compared to PET radionuclides making them more suitable for labelling larger biomolecules such as

Spect vs pet

Single photon emission CT/CT (SPECT/CT) and positron emission tomography/CT (PET/CT) units can perform both exams at the same time. Sep 9, 2013 Generally, SPECT radiotracers last longer in the patient and are primarily used in cardiology where myocardial stress imaging takes about three and SPECT imaging when compared with PET (with respect to image quality the debate on single-photon versus PET imaging is far from being concluded in Dec 22, 2016 PET Scan. The positron emission tomography (PET) scan creates computerized images of chemical changes, such as sugar metabolism, that Sep 10, 2020 A SPECT scan takes about 12–20 min. PET offers faster scan speeds and better image quality due to its higher sensitivity and spatial resolution Mar 10, 2018 Overall, PET more successfully identified patients with severe obstructive CAD and need for revascularization; compared to SPECT, PET scans Dec 3, 2015 Both PET and SPECT use scintillation crystals to convert gamma rays into visible light, and a photomultiplier tube that generates an electrical Feb 10, 2020 Compared with computed tomography (CT) and magnetic resonance imaging ( MRI), such images have lower spatial resolution. However, they Single photon emission computed tomography (SPECT) and positron emission tomography (PET) are nuclear medicine imaging techniques which provide Jun 8, 2012 This clip covers 3 functional Neuroimaging devices - it describes the manner in which the neurological information is gathered, advantages PET vs. SPECT: An MPI Case Review. 7.

PET and SPECT scans use radiopharmaceuticals to create 3D images, but the tracers used are differently. SPECT scans measure gamma rays, and the radiotracers used with PET scans produce small particles called positrons. The detectors in the PET scanner measure these photos to create images of internal organs. PET Scan Images are Clearer

SPECT due to:1-3,6 Higher count rates (240% increase over SPECT) Improved spatial resolution; 3mm PET vs. 6mm SPECT Routine and robust attenuation correction on all scans Better detection of MVD 1.

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. 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. A positron is a particle with roughly the same mass as an electron but oppositely charged. There is, therefore, a direct analogy between planar X-ray/CT and planar scintigraphy/SPECT.

SPECT/CT registration is the process of aligning SPECT andCTimages for the purposes of combined image display (fusion)andimage analysis.
