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...

BACKGROUND Current magnetic resonance imaging (MRI) outcome measures such as T2 lesion load correlate poorly with disability in multiple sclerosis. Diffusion tensor imaging (DTI) of the brain can provide unique information regarding the orientation and integrity of white matter tracts in vivo. OBJECTIVE To use this information to map the pyramidal tracts of patients with multiple sclerosis, i...

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...

OBJECTIVE To determine the accuracy of magnetic resonance imaging criteria for the early diagnosis of multiple sclerosis in patients with suspected disease. DESIGN Systematic review. DATA SOURCES 12 electronic databases, citation searches, and reference lists of included studies. Review methods Studies on accuracy of diagnosis that compared magnetic resonance imaging, or diagnostic criteria...

Tuberous Sclerosis is a genetic multisystemic disease that mainly affects the central nervous system (CNS) of patients at any age. This study illustrates neuroimaging findings are included in clinical diagnostic criteria group with tuberous sclerosis (TS) two tertiary university hospitals. The findings, order frequency, cortical tubers, subependymal nodules, white matter abnormalities and giant...

Since the time that Ormerod, du Boulay, and McDonald wrote their chapter on the neuroimaging of multiple sclerosis (MS ) for the first edition of this volume, continuing advances in the field of magnetic resonance (MR) and MR imaging (MRI) have made tremendous impacts in our understanding of this disease. Over the last few years, findings from (i) “conventional” MRI techniques [e.g., T2-weighte...

Multiple sclerosis (MS) is a chronic disorder of the central nervous system (CNS) in which the complex interplay between inflammation and neurodegeneration determines varying degrees of neurological disability. For this reason, it is very difficult to express an accurate prognosis based on purely clinical information in the individual patient at an early disease stage. Magnetic resonance imagin...

Objectives: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative motor neuron disease whose clinical presentation and evolution varies greatly among patients. The limited role of conventional Magnetic Resonance Imaging in ALS encourages the study of new advanced Magnetic Resonance Imaging (MRI) techniques. Our aim was to review the advances of MRI techniques applied to ALS and to an...

From an extensive serial magnetic resonance imaging (MRI) study in multiple sclerosis (MS) we have identified 4 cases in which disruption of the blood-brain barrier, as detected by gadolinium-DTPA enhancement, preceded other MRI abnormalities and in 1 case clinical evidence of the new lesion. This supports the view that a defect in the blood-brain barrier, and therefore inflammation, is an earl...
