UNLABELLED For interpretation of myocardial perfusion studies, tissue segments are usually assigned to coronary vascular territories based on general assumptions about the most frequent vascular distribution pattern. These assumptions may be inaccurate because of interindividual variability of coronary anatomy. This limitation may be overcome by hybrid(More)
Absolute quantification of myocardial blood flow expands the diagnostic potential of PET for assessment of coronary artery disease. 82Rb has significantly contributed to increasing utilization of PET; however, clinical studies are still mostly analysed qualitatively. The aim of this study was to reevaluate the feasibility of 82Rb for flow quantification,(More)
UNLABELLED Because of the ultrashort tracer half-life and high positron energy of (82)Rb, PET images acquired with this tracer are noisier and of lower resolution than those obtained with other PET tracers. The validity of electrocardiographic gating using (82)Rb for assessment of left ventricular (LV) function is not well established. To support(More)
BACKGROUND Reduction of radiation exposure from computed tomography coronary angiography (CTA) will be a key factor for more liberal use in cardiac hybrid positron emission tomography (PET)-computed tomography (CT). We report our initial experience with a new algorithm for low-dose CTA based on a prospectively gated step-and-shoot technique. This limits(More)
Objectives: The main objective of this study was to observe the behavior of the fetal head position during labor, when starting from occiput anterior or posterior position and also to determine their importance in labor management (if the starting fetal head position can be a strong argument in favour of vaginal or cesarean delivery). Methods:187 patients(More)
PET perfusion imaging with 82Rb is a powerful tool for evaluating coronary artery disease (CAD). Little is known about normal patterns or significance of 82Rb lung distribution in the setting of heart disease. Herein, PET/CT hybrid imaging was used to obtain insights into the frequency and potential radiomorphologic correlates of altered 82Rb distribution.(More)
