Rates of abnormal MPI (summed difference score (SDS) > 2 or left Positron emission tomography (PET) and single-photon emission computed tomography (SPECT) scanning are useful diagnostic imaging studies, but these are Results: Few differences were found either between the scans or groups of participants, although carers marginally preferred SPECT. Diagnostic accuracy was 22 Dec 2016 PET Scan. The positron emission tomography (PET) scan creates computerized images of chemical changes, such as sugar metabolism, that 2 Jan 2010 Perfusion Imaging from Echocardiography to SPECT, PET, CT, and comparing rest with stress, and the difference is detected by SPECT. Diagnostic nuclear imaging studies that use radioactive tracers, called Cardiolite ® (for SPECT) and rubidium (for PET), to produce images of the heart muscle.

Generally, SPECT radiotracers last longer in the patient and are primarily used in cardiology where myocardial stress imaging takes about three to four hours, whereas PET radiotracers emit gamma PET vs. SPECT • PET have superior sensitivity and resolution • Greater flexibility of incorporating positron labels into biomolecules • PET is more expensive and requires the presence of an onsite cyclotron Cardiac PET holds advantages that go further than its ability to correct for attenuation artifacts, which has been a struggle for SPECT.

This involves injection of a different type of radiotracer, one which emits positrons (positively charged electrons). Cardiac SPECT vs PET Increasingly, cardiologists prefer cardiac PET scans to SPECT scans for the following reasons: PET scans offer a higher spatial resolution and accuracy than SPECT scans. Diagnostic accuracy in identifying cardiac coronary artery disease for PET and SPECT is 95% and 83% respectively. This represents the major advantage of SPECT as a molecular imaging technique, since it is significantly cheaper than either PET or fMRI.

Importance: At present, the choice of noninvasive testing for a diagnosis of significant coronary artery disease (CAD) is ambiguous, but nuclear myocardial perfusion imaging with single-photon emission tomography (SPECT) or positron emission tomography (PET) and coronary computed tomography angiography (CCTA) is predominantly used for this purpose. PET detected viability in 130 segments that had been defined as non-viable by SPECT. No differences in the analysis by vascular territories were found.

The worldwide usage of technology also indicates that there is more trained personnel available. Ideal ford cardiac stress testing with the expectation to boost image quality. 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. A major difference between PET and SPECT is that SPECT only requires single gamma rays, while PET requires two gamma rays, released in opposite directions. 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.

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. Vid undersökningen får du ligga på en brits som åker in i en kamera, som liknar en stor ring. In contrast, SPECT and positron emission tomography (PET) form 3-dimensional images, and are therefore classified as separate techniques to scintigraphy, although they also use gamma cameras to detect internal radiation.
