abstract introduction:  this study was performed to compare the effects of low-dose interferon beta-1(cinnovex,30 mcg) and high-dose interferon beta-1(rebif,44 mcg) on the reduction of the number and size of plaques in magnetic resonance imaging (mri) in patients with multiple sclerosis (ms). methods and materials: this historical cohort study, which was performed in 2014 in sanandaj (western p...

Tumefactive multiple sclerosis comprises a rare subset of that often poses diagnostic challenge to physicians. It is unique in its presentation as solitary lesion, usually larger than 2 cm, with surrounding vasogenic edema, commonly mimicking primary intracranial malignancy. We present case 25-year-old female no significant past medical history who presented our institution homonymous superior ...

objective cerebral palsy (cp), a common static motor neurological disorder of childhood with wide spectrum of underlying etiologies, can be demonstrated with different neuro imaging techniques. we undertook this study to investigate the diagnosis of intracranial lesions in children with cp and its correlation between clinical deficits and neuroradiological findings. materials and methods in thi...

epilepsy is an important disease with a cumulative incidence of 3% all over the life and more than half of them are started from childhood. in this study we surveyed magnetic resonance imaging (mri) findings in epileptic children and its relation with clinical and demographic findings in order to find better diagnostic and treatment modalities for these children in the future. in this cross sec...

Balò's concentric sclerosis (BCS) is a rare primary demyelinating disease of central nervous system (CNS) and is considered to be a variant of multiple sclerosis (MS). It is characterized by a severe, rapidly evolving course with CNS lesions consisting of concentric rings of demyelination alternating with myelination in the white matter. We report a patient with BCS from mainland China diagnose...

Our knowledge of the radiological spectrum myelin oligodendrocyte glycoprotein antibody associated disease (MOGAD) is growing rapidly. An update on features disease, and its evolution thus necessary. Magnetic resonance imaging (MRI) has an increasingly important role in differential diagnosis MOGAD particularly from aquaporin-4 antibody-positive neuromyelitis optica disorder (AQP4-NMOSD), multi...

Extensive optic nerve demyelinating lesions on magnetic resonance imaging (MRI) in adults could indicate a diagnosis other than multiple sclerosis with worse prognosis such as neuromyelitis optica. We report the frequency of longitudinally extensive lesions in children with first events of optic neuritis. Subjects had brain or orbit MRI within 3 months of onset and were evaluated at the Univers...

Modern challenges of food science require a new understanding of the determinants of food quality and safety. Application of advanced imaging modalities such as magnetic resonance imaging (MRI) has seen impressive successes and fast growth over the past decade. Since MRI does not have any harmful ionizing radiation, it can be considered as a magnificent tool for the quality control of food prod...

Background: Magnetic resonance imaging (MRI) has improved the diagnosis and management of patients with multiple sclerosis (MS). Montreal Cognitive Assessment (MoCA) is a brief, sensitive test that has been recommended by National Institute of Neurological Diseases and Stroke and Canadian Stroke Network (NINDS-CSN) as a reliable tool to detect mild cognitive impairments. This study aimed to eva...

background: back pain is a common patients' complaint, and its etiology is important because of different potential treatment approaches (based on causes). for a better diagnosis, magnetic resonance imaging (mri) is widely used in clinical settings that may result in inappropriate requests. this study aims to evaluate the appropriateness of the lumbosacral mri requests in patients with back pai...
