In the end, the choice is made by the patients or technicians depending on the advantages and shortcomings of both procedures. Keep reading to know the distinction between PET and SPECT in terms of utility for cardiology. Die Single-Photon-Emissions-Computer-Tomographie (SPECT) und die Positronen-Emissions-Tomographie (PET) sind Verfahren, die zur dreidimensionalen Darstellung von Radioaktivitätsverteilungen im Körper The benefit of using such an integrated system is twofold, as in PET-CT: the transmission images can be used for transmission correction and also for anatomic coregistration when anatomic localization of a lesion is difficult. Unlike PET-CT systems, SPECT-CT systems can also be used in a planar mode.

Die Qualität und die räumliche Auflösung der Aufnahmen ist jedoch deutlich besser als beim SPECT-Verfahren – unter anderem auch, weil die Tot- und Abklingzeiten der verwendeten PET-Kristalle erheblich kürzer sind.

One of the reasons is that attenuation correction is easily achieved in PET, whereas it is (often) not implemented accurately in SPECT [7]. 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. BACKGROUND: Although PET MPI has been shown to have higher diagnostic accuracy in detecting hemodynamically significant CAD than SPECT MPI, whether this impacts downstream management has not been formally evaluated in randomized trials.

The main difference between SPECT and PET scans is the type of radiotracers used. While SPECT scans measure gamma rays, the decay of the radiotracers used with PET scans produce small particles called positrons.

PET and SPECT are clinically indicated for pre-surgical localization of seizure origin. They are covered by most insurance providers. Aug 16, 2017 The addition of either SPECT or PET to CCTA improved the specificity compared with CCTA (SPECT, 97%; and PET, 91%; P < .001) but lowered Current and accurate information for patients about PET/CT.

However, in poorly differentiated highly malignant tumors, FDG-PET might give by PET speaks in favour of functional imaging by PET compared with SPECT Swedish University dissertations (essays) about PET CT. Abstract : The significant increase in the use of CT, alone or combined with SPECT or PET, has can improve satisfaction with care and image quality, compared to standard care.
