Advances in Parallel Transmission

High-performance hardware and exciting application perspectives pave the way of parallel transmission technology into preclinical MRI

3D Inner Volume Imaging

3D Inner Volume Imaging
In 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

Suppression of Artifacts from Pulsatile Flow in the Carotids

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 (“

Spectroscopy in Arbitrarily Shaped Target Volumes

Spectroscopy in Arbitrarily Shaped Target Volumes
Localized 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 sp

Flexible Spin-Labeling for TOF Angiography

Flexible Spin-Labeling for TOF Angiography
TOF 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 caro
