Abstract:
Magnetic resonance imaging (MRI) promises to be an effective, nonivasive means of visualizing intracranial pathology. It should be especially useful in the evaluation of posterior fossa and cervical spinal cord disease of childhood; computed tomographic (CT) evaluation is frequently suboptimal in this region. MRI results are reported for 46 consecutively seen children with posterior fossa and/or cervical spinal cord disease (28 had brain malignancies; seven had congenital anomalies; three had cerebrovascular accidents).

Conventional Magnetic Resonance Imaging (MRI) is a qualitative method for obtaining images of softtissues in patients. Conventional MRI is the standard method used today and it results in gray-scaleimages in which the different magnetic properties of biological tissues determine the image contrast. However, the magnitude of the measured signal is only relative and therefore not directlycomparable between images. Synthetic MRI is a relatively new technique which can be used to postsynthesizedifferent images based on absolute measurement of several magnetic properties oftissues. Synthetic MRI ca

Abstract:
Image registration is the process of aligning two images such that their mutual features overlap. This is of great importance in several medical applications. In 2008 a novel method for simultaneous T1, T2 and proton density quantification was suggested. The method is in the field of quantitative Magnetic Resonance Imaging or qMRI. In qMRI parameters are quantified by a pixel-to-pixel fit of the image intensity as a function of different MR scanner settings. The quantification depends on several volumes of different intensities to be aligned. If a patient moves during the data aquisition the d

Abstract:
The blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) signal is one of the most recently developed imaging techniques used to identify localized changes in brain activity. The BOLD signal is a function of cerebral blood flow (CBF), the cerebral metabolic rate of oxygen consumption (CMRO2), and cerebral blood volume (CBV). Normally coupled changes in these physiological parameters during regional increases in neural activity will result in BOLD signal increases. This makes the BOLD signal useful as a tool for identifying areas of increased neural activity. Moreove
