detection of brain tissues using magnetic resonance imaging (mri) is an active and challenging research area in computational neuroscience. brain mri artifacts lead to an uncertainty in pixel values. therefore, brain mri segmentation is a complicated concern which is tackled by a novel data fusion approach. the proposed algorithm has two main steps. in the first step the brain mri is divided to...

objective: the label and detection of cells injected into target tissues is an area of focus for researchers. iron oxide nanoparticles can be used to label cells as they have special characteristics. the purpose of this study is to examine the effects of iron oxide nanoparticles on human-derived amniotic membrane stem cell (hamcs) survival and to investigate the magnetic properties of these nan...

Several MRI contrast agents (CAs) are used in medical diagnosis that gadolinium (Gd3+) is the most widely used as contrast agents. Unfortunately, its toxicity is due to its inefficiency. In this review, we discuss about the ability of SPIONs in MRI and application in Multiple Sclerosis diagnosis. Superparamagnetic iron oxide nanoparticles (SPIONs) such as magnetite nanoparticles are used as goo...

background and objectives: multiple sclerosis (ms) is the most common demyelinating disease of the central nervous system with more than 5.2 million people across the world being afflicted with. magnetic resonance im­aging (mri) is a valuable tool in the diagnosis of ms. this study surveys the results of mri of the central nervous system and paranasal sinuses in the sample of ms patients in ker...

objectives upon completion of this presentation, participants will be able to: 1) recognize mri appearance of the spontaneous intracranial hypotension and idiopathic intracranial hypertension (pseudotumor cerebri). 2) review their various clinical and imaging presentations. conclusions in this presentation we will review imaging presentations of our several proved cases. as mentioned, there are...

conclusions adc valuecould be a prognostic factor to monitor the response to therapy for patients with cervical cancer. the addition of dw-mri to the conventional mri protocolsconsiderably improved the diagnostic ability of mr imaging method for tumor evaluations. results studies had shown thatthe mean adc value of cervical carcinoma (1.110 ± 0.175 × 10-3 mm2/s)is significantly lower than that ...

the incidence of multiple myeloma (mm) affecting the jaws is 30% and on rare occasions the oral involvement can be the first indication of the disease. authors report a case of mm in a 40-yearold woman who presented with a multilocular radiolucent lesion in the left mandible initially mistaken as an ameloblastoma. conventional radiographs revealed a multilocular lesion on the molar region. comp...
