Perfusion-Based Functional Magnetic Resonance Imaging
The measurement of cerebral blood flow (CBF) is a very important way of assessing tissue viability, metabolism, and function. CBF can be measured noninvasively with magnetic resonance imaging (MRI) by using arterial water as a perfusion tracer. Because of the tight coupling between neural activity and CBF, functional MRI (fMRI) techniques are having a large impact in defining regions of the bra...
متن کاملPerfusion Functional Magnetic Resonance Imaging
Introduction Imaging sequences based upon blood oxygenation level dependent (BOLD) contrast are currently the predominant method for functional magnetic resonance imaging (fMRI) of the brain. BOLD weighted sequences offer both high contrast-to-noise ratio and good temporal resolution. The BOLD signal reflects the total amount of deoxyhemoglobin (dHBO2), and is thus a complex function of cerebra...
متن کاملSoftware Tools for the Analysis of Functional Magnetic Resonance Imaging
Functional magnetic resonance imaging (fMRI) has become the most popular method for imaging of brain functions. Currently, there is a large variety of software packages for the analysis of fMRI data, each providing many features for users. Since there is no single package that can provide all the necessary analyses for the fMRI data, it is helpful to know the features of each software package. ...
متن کاملMagnetic resonance imaging of perfusion.
Recent developments have shown that diffusion and blood microcirculation (perfusion) could be imaged and measured noninvasively by MRI. The purpose of this presentation is to overview the different approaches that use B0 field gradients to monitor diffusion/perfusion. The principles of these different methods are discussed together with their limitations and their potential applications.
