The aim of this study was to determine the variability of various measurement protocols for measurement of abdominal aortic aneurysm (AAA) and the clinical relevance of variability. Three radiologists performed computed tomographic angiography measurements of both the aorta and the largest portion of the aneurysm on selected axial slices. Then measurements(More)
In this paper we address the problem of reconstructing a high resolution volumic image from several low resolution data sets. A solution to this problem is proposed in the particular framework of magnetic resonance angiography (MRA), where the resolution is limited by a trade-o5 between the spatial resolution and the acquisition time, both being(More)
Arterial stiffness predicts cardiovascular events beyond traditional risk factors. However, the relationship with aging of novel noninvasive measures of aortic function by MRI and their interrelationship with established markers of vascular stiffness remain unclear and currently limit their potential impact. Our aim was to compare age-related changes of(More)
Cardiac output and pulmonary vascular resistance (PVR) were measured in 19 patients by means of catheterization of the right side of the heart. Results were compared with the cardiac output and indexes of pulmonary arterial blood flow estimated with velocity-encoded magnetic resonance (MR) imaging. Correlations were good between estimates with right-sided(More)
BACKGROUND Skeletal myoblast (SM) transplantation (Tx) in a post-myocardial infarction (MI) scar experimentally improves left ventricular (LV) ejection fraction (EF). Short-term follow-up (FU) studies have suggested that a similar benefit could clinically occur despite an increased risk of LV arrhythmias. METHODS AND RESULTS We report the long-term FU of(More)
AIMS To investigate the role of the geometry of the aortic arch in resting hypertension after successful repair of coarctation (CoA). METHODS AND RESULTS 105 patients (15.3+/-6 years) with successful repair of aortic CoA underwent blood pressure (BP) measurements at rest and magnetic resonance imaging (MRI) of the aortic arch and left ventricle. Three(More)
BACKGROUND AND PURPOSE Sinus venosus-type atrial septal defect can be associated with anomalous drainage of the upper right pulmonary vein into the superior vena cava. Surgical correction provides reconstruction of superior vena cava and rerouting of the pulmonary vein into the left atrium. SUMMARY OF CASE We report the case of a young woman who(More)
An increasing number of intermediate risk asymptomatic subjects benefit from measures of atherosclerosis burden like coronary artery calcification studies with non-contrast heart computed tomography (CT). However, additional information can be derived from these studies, looking beyond the coronary arteries and without exposing the patients to further(More)
