Real-time functional magnetic resonance imaging
of review evelopments in functional magnetic resonance imaging (fMRI) have catalyzed a new field of nal neuroscience. Using fMRI to monitor the aspects of task-related changes in neural activation or nnectivity, investigators can offer feedback of simple or complex neural signals/patterns back to cipant on a quasireal-time basis [real-time-fMRI-based neurofeedback (rt-fMRI-NF)]. Here, we e some...
متن کاملReal-time functional magnetic resonance imaging.
A recursive algorithm suitable for functional magnetic resonance imaging (FMRI) calculations is presented. The correlation coefficient of a time course of images with a reference time series, with the mean and any linear trend projected out, may be computed with 22 operations per voxel, per image; the storage overhead is four numbers per voxel. A statistical model for the FMRI signal is present...
متن کاملMagnetic resonance imaging in real time: advances using radial FLASH.
PURPOSE To develop technical advances for real-time magnetic resonance imaging (MRI) that allow for improved image quality and high frame rates. MATERIALS AND METHODS The approach is based on a combination of fast low-angle shot (FLASH) MRI sequences with radial data sampling and view sharing of successive acquisitions. Gridding reconstructions provide images free from streaking or motion art...
متن کاملCerebrospinal fluid physiology: visualization of cerebrospinal fluid dynamics using the magnetic resonance imaging Time-Spatial Inversion Pulse method
Previously there have been no methods for directly tracing the flow of cerebrospinal fluid (CSF) under physiological conditions, and the circulation of CSF has therefore been studied and visualized by injecting a radioactively labeled tracer or contrast medium visible in x-ray images. The newly developed Time-Spatial Inversion Pulse (Time-SLIP) method makes it possible to directly visualize the...
