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 is an imaging technique similar to PET that uses radioligands to detect molecules in the body.

It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D information. 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. 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.

Anpassa scanningparametrar till patient . Marie Sydoff, Nuklearmedicinskt vårmöte 2015 Zarówno pozytonowa tomografia emisyjna (PET), jak i tomografia emisyjna pojedynczych fotonów (SPECT) pozwalają na wykrycie nawet niewielkich zmian chorobowych, we wczesnej fazie rozwoju. Czym różnią się te metody i co decyduje o ich zastosowaniu w danym przypadku? Positronemissionstomografi (PET) är en medicinsk avbildningsteknik som bygger på användning av isotopmärkta preparat, så kallade radioaktiva markörer, vilka möjliggör framtagning av tredimensionella bilder av exempelvis ämnesomsättningen i hjärnan men även hur olika preparat, exempelvis signalsubstanser, rör sig i kroppen. SPECT still manages to be the leading choice for cardiac images, although PET is also attracting considerable interest. In the end, the choice is made by the patients or technicians depending on the advantages and shortcomings of both procedures.

PET Scan Images are Clearer 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. PET affords higher image quality, contrast and spatial resolution compared to SPECT and has higher sensitivity (100-1000 times higher than SPECT) in addition to being a more quantitative imaging method than SPECT. However, SPECT scanners are more widely available that PET scanners and the technology is more affordable that PET. SPECT, PET .

SPECT also enables three dimensional imaging and there are today also hybrid SPECT/CT scanners available. Typical procedures are bone scans Various functional, physiologic, and molecular imaging can be performed using a variety of common or new radiotracers produced by the Cyclotron facility by PET and/or SPECT, and by CT when specific contrast agents are used. PET, another nuclear imaging technique, is similar to SPECT but is a more costly imagining technique. Both SPECT and PET scans show areas of the brain that are healthy, overactive, or underactive.

Fluorine-18 and technetium-99m, two commonly used PET and SPECT radionuclides, respectively, possess different emission profiles, offering the potential for imaging one in the presence Table 1 PET and SPECT radioligands for imaging Aβ, tau protein and neuroinﬂammation in AD PET positron emission tomography, SPECT single-photon emission computed t omography, Aβ beta-amyloid Basic principle of PET and SPECT. PET and SPECT are imaging techniques in which a radionuclide is synthetically introduced into a molecule (a ligand, peptide, antibody or antibody fragments etc) of potential biological relevance/interest and administered to an animal or a patient. When the radiotracer is injected into the studied subject, the Single photon emission computed tomography (SPECT) and positron emission tomography (PET) are nuclear medicine imaging techniques which provide metabolic and functional information unlike CT and MRI. They have been combined with CT and MRI to provide detailed anatomical and metabolic information.
