background: early diagnosis of brain tumors has significant effect on the treatment process. brain metastatic tumors are usually diagnosed following the neurological symptoms in patients or incidentally after computerized tomography (ct) scan and magnetic resonance imaging (mri) requests of the brain. objectives: implementation of a new method for being informed about the origin of brain tumors...

this study was conducted to evaluate how neuroimaging procedures (mri, spect) could be used in clinical setting for diagnosis of dementia.forty out of 94 patients suspected of having a diagnosis of dementia, referred to radiology department for consecutive neuroimaging procedures, were selected. patients’ medical records reviewed anda retrospective diagnosis was reached according to dsm-iv for ...

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 ...

we report an unusual case of hemimegalencephaly (hmg) associated with ipsilateral congenital-infiltrating lipomatosis of the face in a five-month-old boy. hemimegalencephaly is a rare but unique malformation characterized by enlargement of all or parts of a cerebral hemisphere. the affected hemisphere may have focal or diffuse neuronal migration defects, with areas of polymicrogyria, pachygyria...

introduction: 5-ht1a receptor is related with a variety of neuropsychiatric disorders. . in this study a phenolic analogue derived from dway [desmethyl way-100635 (n-(2-(1-(4-(2-methoxyphenyl)piperazinyl)-ethyl))-n-(2-pyridinyl) cyclohexanecarboxamide)] is used to design the desired structure of 5-ht1a receptor imaging agents after labeling with [99mtc (co) 3(h2o) 3] + core via dithiocarbamate ...

this paper introduces a novel methodology for the segmentation of brain ms lesions in mri volumes using a new clustering algorithm named scpfcm.  scpfcm uses membership, typicality and spatial information to cluster each voxel. the proposed method relies on an initial segmentation of ms lesions in t1-w and t2-w images by applying scpfcm algorithm, and the t1 image is then used as a mask and is ...

aim and background: it has since long been known that there is strong relation between   psychological status and functional gastrointestinal disorders (fgid). however, until recently, the nature of this putative relationship was unclear due to a lack of non-invasive methods to investigate the neurobiological mechanisms underlying this relationship.  functional brain imaging has provided a meth...

the purpose of this study was to investigate the brain activation patterns in response to thehuman color preference by using a functional magnetic resonance imaging (fmri). a total of 31 healthyhumans without color blindness were participated in this study. the brain activation was induced by viewingof eight different colors: black, gray, blue, green, earthy yellow, red, yellow and white. the q...
