Typically, the patient is given an injection of a substance that consists of a combination of a sugar and a small amount of radioactively labeled sugar. SPECT and PET are both used for cardiac imaging, although SPECT is more broadly available. Each has its own strengths and challenges, but each can provide quality images that allow for accurate diagnosis. Is one better than the other?

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. Single photon emission computed tomography/computed tomography (SPECT/CT) and positron emission tomography/computed tomography (PET/CT) units can perform both exams at the same time. PET/MRI is an emerging imaging technology.

Localization of defects is more precise and more clearly seen. Extent and size of defect is better defined.

Whether it is a SPECT or positron system, our phantoms and related accessories provide medical imaging investigators with the ability to test imaging equipment and validate that the medical imaging is done correctly and accurately.

Den används vid medicinsk diagnostik. Den använder sig av en eller flera gammakamerahuvuden för att registrera gammastrålning från en injicerad radionuklid i patienten.

SPECT (Single Photon Emission Computed Tomography)：是单光子发射型计算机断层成像的英文字头缩写。. PET (Positron Emission Computed Tomography)：是正电子发射型计算机断层成像的英文字头缩写。. 因此，从定义范围上看ECT包括SPECT和PET，由于SPECT设备数量多，应用临床早及范围广，通常上就把SPECT叫做ECT，久而久之，ECT就 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. Gammakamera används inom medicinsk bildgivning och kallas även scintigrafi.Det är en del av nuklearmedicinen eftersom man använder radioaktiva isotoper som sprutas in i blodbanan för att fästa sig på det området som skall undersökas. Hospitals use two main forms of emission imaging: positron emission tomography ( PET) single-photon emission computerised tomography ( SPECT) Both work on the same basic principles - detecting Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays.

Due to better image resolution and quantification, PET is frequently preferred, if approved tracers with the same characteristics as compared to the respective SPECT tracers are available. However, SPECT radionuclide’s are more widely available and have a longer physical half life, so that these radiopharmaceuticals are preferable for certain clinical investigations . PET står för, Positronemissiontomografi och SPECT, står för Single Photon Emissioin Computed Tomography. Det speciella med dessa är att de även är en hybrid tillsammans med en CT (datortomografi) Så det är två apparater i ett!

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.

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

Nuclear medicine is a type of medical imaging that uses a small amount of radioactive material known as a tracer. 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. 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.

Continuing our series of Reviews on Molecular Imaging, Drs. Dobrucki and Sinusas discuss the applications of PET and single photon emission CT (SPECT) for the evaluation of cardiovascular disease 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.
