Background—Coronary endothelial function and vasomotion are impaired in smokers without
coronary disease, and this is thought to be due to increased oxidative stress. Methods and …

Gating methods acquiring biosignals (such as electrocardiography [ECG] and respiration)
during PET enable one to reduce motion effects that potentially lead to image blurring and …

Respiratory gating is used for reducing the effects of breathing motion in a wide range of
applications from radiotherapy treatment to diagnostical imaging. Different methods are feasible …

Background— Matrix metalloproteinases (MMPs) are enzymes involved in the proteolytic
degradation of extracellular matrix. They play an important role in several disease processes, …

OBJECTIVES The present study evaluates the impact of total cholesterol (TC) and its
subfractions on coronary flow reserve (CFR), an index of the integrated function of the coronary …

Motion is a source of degradation in positron emission tomography (PET)/computed
tomography (CT) images. As the PET images represent the sum of information over the whole …

The problem of motion is well known in positron emission tomography (PET) studies. The
PET images are formed over an elongated period of time. As the patients cannot hold breath …

Background— Patients with Brugada syndrome present with characteristic ECG
abnormalities (atypical right bundle-branch block and ST-segment elevation) and life-threatening …

Respiratory and cardiac motion leads to image degradation in positron emission tomography
(PET) studies of the human heart. In this paper we present a novel approach to motion …

Aims Patients with atrial fibrillation (AF) present with symptoms of myocardial ischaemia
despite exclusion of coronary artery disease. A small vessel disease has been suggested. We …
