Introduction: Despite growing interest in the use of magnetic resonance imaging (MRI) in the external radiotherapy design process (RT), Computer Tomography (CT) remains a gold standard and is regarded as a basic imaging modality in radiotherapy. MRI shows the high contrast in soft tissues without any radiation exposure to patients. As a result, MRI is used in functional tissue ...

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 ...

Accurate segmentation of brain tumor plays a key role in the diagnosis of brain tumor. Preset and precise diagnosis of Magnetic Resonance Imaging (MRI) brain tumor is enormously significant for medical analysis. During the last years many methods have been proposed. In this research, a novel fuzzy approach has been proposed to classify a given MRI brain image as normal or cancer label and the i...

g20 world brain mapping initiative (neuroscience/n-20) is putting brain mapping on the top of global economic issues the society for brain mapping, therapeutics, and brain mapping foundation are propelling therapeutic advances in nano-neurosurgery, nano-bio-electronics, artificial intelligence, neuro-supercomputing and ‘cross-pollination’ among the bio-medical sciences and engineering worldwide...

conclusion the minimum concentration of triolein emulsion required to increase vascular permeability adequately with minimal brain edema in a cat model was 0.5%. results the lesion hemispheres showed mild hyperintensity due to edema on t2-weighted images, and contrast enhancement on post-contrast t1-weighted images in cats of group 1-5. cers showed statistically significant differences between ...

In a patient with features indicating the presence of pseudotumor cerebri, a negative cranial CT-scan is not adequate to rule out less benign pathology and an MRI of brain should be performed. In this study, a 10-year old boy with daily headaches for one month and diplopia for one week was found to have a partial abducens palsy and bilateral papilledema; otherwise, his examination was normal. A...
