High-performance hardware and exciting application perspectives pave the way of parallel transmission technology into preclinical MRI3D Inner Volume ImagingIn a pilot scan (a) the brain is selected as a target for inner volume imaging. This volume is then selectively excited using 3D parallel spatially selective excitation (b). The high accuracy of the selection allows the reduction of the FOV to the excited volume and imaging of this volume with a 66 % increased resolution in unchanged measurement time (c).

This application is still under development and not yet commercially available. Its future availability cannot be ensured.

Suppression of Artifacts from Pulsatile Flow in the Carotids(a): Motion or pulsatile flow can cause artifacts along the phase encoding direction.

(b): Parallel spatially selective excitation of the brain region only leads to an artifact-free brain image, since the artefact causing structures are not excited (“selective non-excitation”).

This application is still under development and not yet commercially available. Its future availability cannot be ensured.



Spectroscopy in Arbitrarily Shaped Target VolumesLocalized spectroscopy in the rat head: Comparison of proton NMR spectra from a standard rectangular voxel and an adapted “whole brain” voxel (see ROIs in (a)). It is shown that such adapted voxels can be selected with very good accuracy using parallel spatially selective excitation (b). With adapted voxels, an SNR gain is achieved in the spectra (c) by maximizing voxel volumes and simultaneously minimizing partial volume effects.

This application is still under development and not yet commercially available. Its future availability cannot be ensured.

Flexible Spin-Labeling for TOF AngiographyTOF angiography in the rat head: (a) conventional TOF acquisition; (b): TOF with 3D parallel spatially selective saturation (labeling) of spins in one carotid results in suppression of signal from this vessel; (c): difference image yields the labeled carotid and the vasculature supplied by this vessel only.
