the application of magnetic resonance to diagnostic medical imaging stands as one of the great scientific achievements in the past 50 years. magnetic resonance techniques are easily applied to organs which remain stationary during the imaging procedure, such as the brain and musculoskeletal system. imaging of moving heart structures and circulating blood is considerably more difficult.   clinic...

A 20-year-old woman was admitted to a Gynecology Hospital in her 6th month of pregnancy for high blood pressure and tonic-clonic seizure. Primary diagnosis was eclampsia, and for that reason she underwent cesarean section. She also had headache on frontal and parietal areas without nausea or vomiting. There was not a focal neurological sign. Rheumatology consultation was requested. Systemic lup...

Changes in iron concentration in brain tissue are of interest in the study of neurodegenerative diseases such as Alzheimer’s and multiple sclerosis [MPY13]. Magnetic resonance imaging (MRI) is inherently sensitive to changes in tissue magnetic susceptibility, which can be used as a direct measure of iron concentration [Sch96]. Changes in tissue magnetic susceptibility result in phase shifts in ...

two dogs with generalized seizures were evaluated. the dogs were diagnosed with traumatic intracranial hemorrhages based on the history, neurological examinations, and magnetic resonance imaging (mri) of the brain. treatment was started with oxygen, prednisolone and anticonvulsant agents. no further seizure activity was observed after treatment in both dogs, however cushing reflex was detected ...

background: there are conficting reports regarding the association between coronary artery disease (cad) and mild cognitive  impairment (mci). volumetric magnetic resonance imaging (mri) investigations have been considered as an objective biomarker for  mci. in this study, we determined the relationship between the regional brain volumes and the extent of cad in mci patients and  cognitively no...

functional magnetic resonance imaging (fmri) is a safe and non-invasive way to assess brain functions by using signal changes associated with brain activity. the technique has become a ubiquitous tool in basic, clinical and cognitive neuroscience. this method can measure little metabolism changes that occur in active part of the brain. we process the fmri data to be able to find the parts of br...

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...

Background and Aim: Brain tumors have remained as a significant cause of morbidity and mortality and are often refractory to treatment. The grading of brain tumor has an important implication in clinical management. Currently, magnetic resonance spectroscopy (MRS) is an important dimension in evaluating metabolites and grading brain tumors. The aim of this study is to evaluate metabolites in br...

because of continuous changing of anatomy, function and metabolism of the human brain, age- related change is a major risk factor in most prevalent neurodegenerative diseases, including parkinsons and huntingtons disease. therefore, knowing patterns of age-related atrophy of brain tissue can identify causes and possible role of diseases in decreasing brain function with age. the aim of this stu...
