A positron is a particle with roughly the same mass as an electron but oppositely charged. 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.

Comparison between spect and pet comparison between spect and pet comparison of pet and spect imagingkt PET/CT scans not only pinpoint localization; they also offer significant help with attenuation correction, a huge advantage. During a CT scan, the system records numbers, called Hounsfield units, which measure the density of the tissue that it travels through. The differences in PET and SPECT scanner performance characteristics (such as spatial resolution and sensitivity) and their relationship to radionuclide  Consequently, in SPECT the scatter radiation is more difficult to reduce than in PET. This is just one difference. In general, one can say that the spatial resolution   3 Dec 2015 Both PET and SPECT use scintillation crystals to convert gamma rays into visible light, and a photomultiplier tube that generates an electrical  In this paper, the first three sections compare capabi- lities in PET and SPECT in terms of sensitivity, spatial resolution and temporal resolution, respectively. Quantitative comparison of PET and SPECT for imaging the yttrium-90 microsphere distribution after liver radioembolization.

As a noun pet is an animal kept as a companion or pet can be a fit of petulance, a sulk, arising from the impression that one has been offended or slighted or pet can be or pet can be (geordie) a term of endearment usually applied to women and children. 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. 2013-07-23 · In cardiac scanning, it has generally been reported that PET offers a resolution of 5 to 7 mm, compared with a cardiac SPECT resolution of 12 to 15 mm. Better performance has allowed data to emerge suggesting that as many as one in 10 scans interpreted as normal on SPECT would have been abnormal if done on PET due to the presence of unseen microvascular, triple-vessel disease.
