An annual international symposium that invites individuals in the fields of neuroscience, physics, radiology, and many more disciplines to join together to push the boundaries of in-vivo Magnetic Resonance Spectroscopy (MRS). This Symposium is an opportunity to present advanced MRS study, to a broad audience with a common interest in developing methodology and overcoming limitations.

EDITING SCHOOL is a 3-day (sometimes more - sometimes less) course exclusively dedicated to advanced Magnetic Resonance Spectroscopy (MRS). While it was originally designed to have a strong focus on theory of edited spectroscopy, editable metabolites, and editing methodology.. the course has expanded to cover background in MRS theory, analysis software, and practical tips for successful MRS studies.

GannetLoad Output
A. The plot top left shows the processed GABA-edited difference spectrum, the key output of the GannetLoad module. This plot shows the spectrum before frequency and phase correction above in green and the spectrum after frequency and phase correction…

GannetFit Output
A. The plot top left shows the modeling of the GABA signal. The GABA-edited spectrum is shown in blue (across a more limited ppm range than in the GannetLoad output). Overlaid in red is the model of best fit (using a simple Gaussian model by default)…

GannetCoRegister Output
GannetCoRegister takes location and orientation information from the headers of MRI and image data, and generates a binary mask representing the voxel location in the matrix of the image. This is then visualized in three planes.
Read moreGannetSegment
GannetSegment Output
GannetSegment calls an SPM segmentation of the T1-weighted anatomical image, and reports the tissue fractions of the voxel mask generated by GannetCoRegister. If the segmentation has already been run, the prior output files will be used instead…

GannetQuantify Output
GannetQuantify is the final step, combining modeled peak areas from GannetFit and voxel tissue fractions from GannetSegment with preset values for GABA and water relaxation and visibility, to deliver concentration values. Currently several values are…

Common Error
The single commonest error in Gannet arises from mis-setting the switches onofforder or WaterPositive in GannetPreinitialise.m. These switches correspond respectively to whether the first average is an edit-ON or edit-OFF average, and whether the res...
