objective multiple sclerosis (ms) is an inflammatory demyelinating disease of central nervous system (cns) that is increasingly being recognized as a disease affecting children. however, the clinical features of childhood ms at onset have been rarely reported from asia. materials & methods this report presents a retrospective chart review of 26 patients with ms (20 females and 6 males), with an...

Magnetic resonance imaging (MRI) provides an in vivo assessment of cortical and subcortical regions affected in Parkinson's disease (PD). This review summarizes the most important conventional and non-conventional MRI techniques applied in this field. Standard neuroimaging techniques have played a marginal role in the diagnosis and follow-up of PD, essentially being used only to discriminate at...

abstract background: a tumefactive lesion of central nervous system (cns) is defined as a mass-like lesion with a size greater than 2 cm in brain (magnetic resonance imaging) mri. neuroimaging may help to distinguish the nature of a tumefactive lesion and therefore can prevent an unnecessary brain biopsy. method: in this paper, we have emphasized on determining the nature of a cns tumefactive l...

background: the monoclonal antibody, c595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (gd-cdtpaa) to produce gd-dtpa-c595 and used as specific breast cancer cell line (mcf-7) contrast agents in magnetic resonance imaging (mri).  methods: after incubation of breast cancer cell line (mcf-7), with different contrast agents (g...

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...

Functional Magnetic Resonance Imaging (functional MRI or fMRI) is a noninvasive neuroimaging technique that can be used for studying human brain function in vivo. Functional MRI extends the use of Magnetic Resonance Imaging to provide information about biological function in addition to the anatomical information. Seiji Ogawa first demonstrated that by measuring the blood-oxygenation-level-depe...

Over the last 20 years, the impact of imaging on the clinical sciences has been immense. Tremendous progress has been made in medical imaging of the human body since the invention of computed tomography (CT) and magnetic resonance imaging (MRI). Neuroimaging of patients with metal neurotoxicity can be divided into two types: morphological neuroimaging (anatomy-based imaging) including CT and MR...

Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...

It is now common practice to use neuroimaging tools, particularly magnetic resonance imaging (MRI), identify the affected vascular area of a stroke patient's brain and inform clinical treatment choices. These tools have significantly improved our ability visualize structures. MRI also was known demonstrate size accurate location bleeding. The principle 'time brain' guides care victi...
