AbstractBackground: Transient ischemic dilation (TID) measures left ventricle (LV) volume changes which can be associated with combination of myocardial and endocardial ischemia. Various stress methods, single photon emission computerized tomography (SPEC... see more

Background: The advantage of total arterial off-pump coronary bypass grafting (OPCAB) over conventional on-pump coronary artery bypass grafting with 1 internal thoracic artery and veins (CCAB) in terms of myocardial flow reserve has not been studied. We s... see more

AbstractObjectives: To assess initial experience with the use of a new single-photon emission computed tomography-computed tomography (SPECT-CT) in the evaluation of lesions.Methods: The folder number, radiopharmaceutical used and type of scan of patients... see more

This article provides an overview of neuroimaging biomarkers in experimental epileptogenesis and refractory epilepsy. Neuroimaging represents a gold standard and clinically translatable technique to identify neuropathological changes in epileptogenesis an... see more

Positron emission tomography (PET) is a powerful diagnostic tool, especially for Oncology. In PET procedures, the hands exposition of the workers is potentially higher than the thorax exposition due to the direct handling of the high-energy photons radion... see more

BACKGROUND: Pancreatitis severity is an important death rate indicator that plays a crucial role in deciding on proper handling of patients at their initial admission, when making a decision on patient’s transfer to the intensive care unit. Many studies p... see more

 Spontaneous or phasic voltage shifts normally occur across the plasma membranes of photoreceptors without impingement from external photons on average once every ~38 s (26 mHz). There have been arguments that all living cells spontaneously exhibit B... see more

Objective: It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. Th... see more

Background: The aim of the present study was to assess the upper information content bound of positron emission tomography (PET) images, by means of the information capacity (IC). Methods: The Geant4 Application for the Tomographic Emission (GATE) Monte C... see more
