PET/CT units with high temporal resolution (particularly with 64-slice CT capability) are increasingly used as in clinical diagnosis and prognosis of cardiovascular disease. Since the CT sub-system in the combined PET/CT unit is used to perform attenuation correction of acquired PET data, misalignments between patient positioning for both scans can cause artifacts in the myocardial PET images potentially resulting in false positive artifacts. The aim of this study is to evaluate the… CONTINUE READING
