conclusion a higher magnetic field strength and a decrease in the hr resulted in an increase in body temperature during the mri procedure. results our investigation of the physiological response to rf heating indicated a link between increasing age and body temperature. a higher increase in body temperature was observed in older patients after a 3.0-t mri (r = 0.07, p = 0.29 for 1.5-t mri; r = ...

conclusions the results of this study suggest that mri does not increase microleakage of amalgam restorations. results in teeth with amalgam filling, there were no significant differences of occlusal and gingival surface microleakage after mri exposure. occlusal and gingival surface microleakages were also similar with and without mri in teeth with bonded amalgam filling. materials and methods ...

background morphometric data of the frontal lobe are important for surgical planning of lesions in the frontal lobe and its surroundings. magnetic resonance imaging (mri) techniques provide suitable data for this purpose. objectives in our study, the morphometric data of mid-sagittal mri of the frontal lobe in certain age and gender groups of children have been presented. patients and methods i...

background: gliomas are the most common primary neoplasms of the central nervous system. relative cerebral blood volume (rcbv) could estimate high-grade gliomas computed with dynamic susceptibility contrast mr imaging which it is artificially lowered by contrast extravasation through a disrupted blood-brain barrier. objectives: our intent was to clarify the usefulness of diffusion-weighted magn...

we report a patient diagnosed with whipple's disease (wd) who presented only with neurological symptoms. neuroimaging (mri) showed lesions with marked mass effect similar to infiltrative tumors, which were hypersignal on long tr and hyposignal on short tr images, located in several areas of the brain. in serial controls, lesions resolved with gliosis and atrophic changes as well as migration of...

background: carbon monoxide (co) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. magnetic resonance imaging (mri) has a well-recognized role in assessment of the severity of brain damage caused by co poisoning. in this study, we aimed to present and analyze the structural abnormalities in the brain mri and especially in diffusion weighted mri (dwi) images in ...

introduction while primary malignant tumors of the heart are rare, angiosarcomas are the most common cardiac malignant tumors. case presentation we describe a 23-year-old woman who presented with a right atrial mass, which was discovered to be a cardiac angiosarcoma. we demonstrate the use of several noninvasive imaging modalities along with pathology confirmation for the definitive and compreh...

Introduction: Staff and patient Movement in static magnetic field MRI scanner induces current density in the human tissues, so cause biologic effects in people. The aim of this study was the Modelling of current density induced by moving individual with different velocities in static magnetic field of magnetic resonance imaging. Materials and Methods: current ...

Abstract. Polarisation transfer schemes and indirect detection are central to magnetic resonance. Using the trityl radical OX063 a pulse electron paramagnetic resonance spectrometer operating in Q-band (35 GHz, 1.2 T), we show here that it is possible use pulsed dynamic nuclear polarisation (DNP) from electrons protons back. The latter achieved by first saturating then simply using reverse DNP ...
