PURPOSE Identification of the precentral gyrus can be difficult in patients with brain tumors. The purpose of the current study was to evaluate the clinical usefulness of functional MRI (fMRI) in identifying motor cortex and speech areas as a part of preoperative neurosurgical planning. METHOD fMRI was performed using a 1.5 T MR unit in 41 patients with(More)
CONTEXT Multislice computed tomography (MSCT) has recently evolved as a modality for noninvasive coronary imaging. OBJECTIVE To assess the accuracy and robustness of MSCT vs the criterion standard of invasive coronary angiography for detection of obstructive coronary artery disease. DESIGN, SETTING, AND PATIENTS Prospective, single-center study(More)
PURPOSE To evaluate the effect of heart rate on the quality of coronary angiograms obtained with 16-detector row computed tomography (CT) by using temporally enhanced three-dimensional (3D) approaches. MATERIALS AND METHODS The local ethics committee approved the study, and informed consent was obtained from all patients. Fifty patients underwent coronary(More)
BACKGROUND The TransEurope FootRace 2009 (TEFR09) was one of the longest transcontinental ultramarathons with an extreme endurance physical load of running nearly 4,500 km in 64 days. The aim of this study was to assess the wide spectrum of adaptive responses in humans regarding the different tissues, organs and functional systems being exposed to such(More)
BACKGROUND Almost nothing is known about the medical aspects of runners doing a transcontinental ultramarathon over several weeks. The results of differentiated measurements of changes in body composition during the Transeurope Footrace 2009 using a mobile whole body magnetic resonance (MR) imager are presented and the proposed influence of visceral and(More)
BACKGROUND Systematic aerobe training has positive effects on the compliance of dedicated arterial walls. The adaptations of the arterial structure and function are associated with the blood flow-induced changes of the wall shear stress which induced vascular remodelling via nitric oxide delivered from the endothelial cell. In order to assess functional(More)
The purpose of the present study was to ascertain whether artificial skull deformation, carried out during infancy, has an effect on the pneumatization of the frontal and maxillary sinuses and on the osseous structure of the frontal bone. Thus, two normal and 12 artificially deformed adult human skulls (12 males, two females) from the collection of(More)
BACKGROUND Intragastric balloons are used for short term weight loss therapy in obese. It is possible to monitor the ballon with sonography, however this method is sometimes insufficient in obese patients. Therefore MRI seems to be a potential therapy-monitoring option. PURPOSE In this feasibility report we want to demonstrate the potential use of(More)
