Background Behçet’s Disease (BD) is a chronic multisystem vasculitis that manifests with recurrent oral/genital ulcerations and destructive inflammation affecting eyes, central nervous system, blood vessels. Venous thrombosis observed in up to 40% of patients, however pathology vein involvement BD poorly characterized [1]. Recently, demonstration wall thickening posterior common femoral an ultr...

in this paper, a novel decision based median (dbm) filter for enhancing mr images has been proposed. the method is based on eliminating impulse noise from mr images. a median-based method to remove impulse noise from digital mr images has been developed. each pixel is leveled from black to white like gray-level. the method is adjusted in order to decide whether the median operation can be appli...

brachial plexus injury (bpi) is an uncommon complication of median sternotomy capable of causing a permanent or transitory sensitivity and/or motor function impairment in the upper limbs. during a cardiac surgery through sternotomy, for the assessment of the thoracic cage configuration and the site of mediastinal structures, a broader surgical field may be required. if the sternal retractors ar...

conclusion distinct neurochemical and histological structure changes (cortico-striatal-thalamic-cortical cycle) exist in patients with first-episode ocd. 1h-mrs is capable of identifying these changes by assessing metabolic abnormalities. objectives this study aims to use magnetic resonance spectroscopy (mrs) to discover substance-metabolism abnormalities of brain circuits in patients with firs...

introduction quantitative susceptibility mapping (qsm) is a new contrast mechanism in magnetic resonance imaging (mri). the images produced by the qsm enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. these nuclei are targets in many clinical applications and therefore their easy localization is a must. in this study, we aimed to i...
