Transient ischemic dilation (TID) in the setting of abnormal stress–rest cardiac SPECT myocardial perfusion imaging (MPI) has been linked with increased cardiovascular risk. However, the significance ...

The image quality of myocardial perfusion images acquired with a PET system depends on the radiotracer used in the study. The commonly used radiotracers in cardiac PET imaging are 15 O-water (H 2 15 O ...

Accuracy of PET is greatly reduced by the limited spatial resolution of the scanner and the resulting partial volume (PV) effects. Although various methods have been proposed for PV correction (PVC) ...

The results are presented as median and interquartile range (IQR) for continuous variables and as number and percentage for categoric variables. Kaplan–Meier analysis was used to estimate overall ...

The accurate quantification of radiotracer activity in a vascular wall plaque on PET can be problematic. Because most atherosclerotic plaques are small and exhibit complex morphology, it can be quite ...

PET/CT is commonly performed in the staging of malignancy and in determining disease response, most commonly with 18 F-FDG, although one of the limitations of PET is its relatively low, 5-mm, spatial ...
