BACKGROUND Pulse wave velocity (PWV) is a biomarker for arterial stiffness, clinically assessed by applanation tonometry (AT). Increased use of phase-contrast cardiac magnetic resonance (CMR) imaging allows for PWV assessment with minor routine protocol additions. The aims were to investigate the acquired temporal resolution needed for accurate and precise(More)
PURPOSE Recent years brought several experimental and clinical reports applying diffusion tensor tractography imaging (DTI) of the brain in epilepsy. This study was aimed to evaluate current evidence for adding the DTI sequence to the standard diagnostic magnetic resonance imaging (MRI) protocol in pediatric epilepsy. MATERIAL AND METHODS Rapid and(More)
The number of patients with cardiac pacemakers (PM), implantable cardioverter-defibrillators (ICD) and cardiac resynchronisation therapy PM systems is increasing. The number of magnetic resonance imaging (MRI) examinations is also growing and amounts to about 60 million tests per year worldwide. The presence of an ICD is still considered to be an absolute(More)
Frontal aslant tract (FAT) is a white matter bundle connecting the pre-supplementary motor area (pre-SMA) and the supplementary motor area (SMA) with the inferior frontal gyrus (IFG). The purpose of the present study was to evaluate the anatomical variability of FAT. Total number of fibers and the lateralisation index (LI) were calculated. We attempted to(More)
BACKGROUND Takotsubo cardiomyopathy (TTC) is often triggered by emotional or physical stress factors. Psychological variables can have an impact on the physical manifestations of heart disease. TTC may reflect stunned myocardium from a neurogenic source. Anatomical connections between different parts of the brain can be visualized by diffusion tensor(More)
OBJECTIVES Our study aimed at exploring structural and functional differences in the brain during higher cognitive processing between middle-aged hypertensive patients and controls matched for sex, age and years of education. METHODS Two groups of 20 patients took part in MRI examinations. This article reports the results of functional MRI during a Stroop(More)
