The physician in the cath lab was blinded to the results of the noninvasive testing, and raw image data from CTA, PET, and SPECT were sent to three independent core laboratories to interpret the findings. 2017-10-10 · I keep getting PET (Positron Emission Tomography) and SPECT (Single Photon Emission Computed Tomography) mixed up in my head and so to help me clear up the difference between the two (bar the obvious S and C) I thought I would dedicate this week's blog to them both. Una apparecchiatura PET costa circa 10 volte più di una SPECT (0.5-1 ml euro) e non richiede la contemporanea presenza di un ciclotone; per questa ragione le prime sono molto meno presenti sul territorio Esistono differenze tra le tecnologie di acquisizione SPECT e PET. There is one key difference between SPECT-CT and PET-CT. The cost of the integrated device parts is heavily weighted toward CT if a high-end CT is used in a SPECT-CT system, and SPECT data acquisition is substantially slower than PET data acquisition.

However it lacks good spatial (i.e., where exactly the particle is) or temporal (i.e., did the contrast agent signal happen at this millisecond, or that millisecond) resolution. 2014-11-11 · SPECT and 18F-FDG PET differ in the equipment needed, im-age characteristics, availability, and patient experience. 18F-FDG PET allows brain metabolism to be directly assessed and offers spatial resolution superior to SPECT (;5 vs.10 mm).

No differences in the analysis by vascular territories were found. Thirty percent of the segments that were defined as non viable by SPECT were viable by PET, meanwhile only 1% of the segments detected viable by SPECT were considered non viable with PET.

The final method is positron emission tomography (PET). 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.
While these advanced imaging techniques are common today, there is often confusion about what the differences are and more so, when how they are best used and when.
