GE’s advancements in neuro imaging
continue with the delivery of Optima Edition
enhancements. In short, Signa HDxt 1.5T
Optima Edition is a natural for neuro.
PROPELLER *
Correct for motion artifacts and enhance
tissue contrast without compromising image
resolution or prolonging scan time — and reduce
susceptibility artifacts to clearly visualize small
or subtle lesions. Generate consistently
excellent images with less retakes, even on
restless children, or patients with tremors.
BrainWave
A suite of applications for functional brain
mapping. Includes a robust acquisition
sequence, easy-to-administer paradigms and
complete post-processing and visualization
tools. BrainWave Fusion integrates an
eloquent cortex map and DTI white-matter
trajectories with a high-resolution 3D anatomy
data set.
Enhanced DWI
The enhanced DWI technique supports multiple b-values in one acquisition with flexible control of NEX for each b-value. Novel diffusion techniques
“3-in-1” and “tetrahedral” allow applying gradients in multiple directions simultaneously to improve scan efficiency and signal-to-noise ratio.
SWAN
SWAN is a multi-echo 3D imaging
technique that helps visualize
and clearly delineate small vessels
and microbleeds, as well as large
vascular structures, and iron or
calcium deposits in the brain. This
image of the entire brain with the
0.5 x 0.6 x 2 mm voxel was
acquired in 4:50 min.
