PROPELLER DWI
PROPELLER DWI corrects for susceptibility
artifacts at air/tissue interfaces, which
are commonly seen in the temporal lobes
when using standard EPI sequences.
It also reduces artifacts from dental and/or
surgical implants.
High-resolution 3D TOF MRA demonstrating the
benefits of the additional SNR provided
by OpTix RF. SWAN
SWAN is a unique 3D T2*-weighted technique
that provides the ability to clearly delineate
small vessels. As a 3D application, SWAN
benefits from the added SNR of the OpTix
optical RF technology.
3D Arterial Spin Labeling (3D ASL)
This technique offers full-brain coverage,
delivering robust, high-SNR 3D images. It works
by generating a 3D FSE acquisition with spiral
readout, with pulsed continuous labeling close
to the image slab. Background suppression
is then added for motion insensitivity. The
application is great for evaluating cerebro-
vascular conditions such as stroke.
