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...

radical resection of a pathological lesion along with the preservation of eloquent cerebral tissue is the principle goal of neurosurgery. brain lesions are usually diagnosed by conventional magnetic resonance imaging (mri), but this method is unable to describe the relationship between lesions and neighboring specific white matter (wm) tracts. diffusion tensor tractograghy (dtt) is a new sophis...

introduction: multiple sclerosis (ms) is a demyelinating disease of the central nervous system (cns), affecting mostly young people at a mean age of 30 years. magnetic resonance imaging (mri) is one of the most specific and sensitive methods in diagnosing and detecting the evolution of multiple sclerosis disease. but it does not have the ability to differentiate between distinct histopathologic...

Introduction: Neuromyelitis Optica (NMO) is a rare inflammatory disease of the central nervous system which generally affecting the spinal cord and optic nerve. Damage to the optic nerve can result in the patient's dim vision or even blindness, while the spinal cord damage may lead to sensory and motor paralysis and the weakness of the lower limbs in the patient. Magnetic Reson...

Brain stimulation techniques are important in both basic and clinical studies. Majority of well-known brain stimulating techniques have low spatial resolution or entail invasive processes. Low intensity focused ultrasound (LIFU) seems to be a proper candidate for dealing with such deficiencies. This review recapitulates studies which explored the effects of LIFU on brain str...

Background Access to appropriate images of fetal brain can greatly assist to diagnose of probable abnormalities. The aim of this study was to compare the suitability of T2-True Fast Imaging with Steady State Free Precession (T2-TRUFI), and T2-Half-Fourier Acquisition Single-Shot Turbo Spin-Echo (T2- HASTE( magnetic resonance imaging (MRI) to extract the fetal brain using the level set algorithm...

background: in order to assign appropriate planning target volume (ptv) margins, each centre should measure the patient positioning deviations for their set-up techniques. at the royal marsden hospital, uk, a conformal shell (cast) system is used when a stereotactic frame is not suitable. in this paper, we report on a series of measurements with the aim of obtaining the systematic and random co...

this report describes the case of a 56 year-old man with a history of diplopia. his brain imaging showed multiple lesions with a metastatic appearance, however all investigations to determine the primary source of malignancy were negative. the patient underwent a brain biopsy, which was positive for anaplastic astrocytoma, a rare tumor that should be considered in the differential diagnosis of ...
