We demonstrate the feasibility of combining multi-band
acceleration with 3D multi-slab, multi-echo acquisition for simultaneous time-of-flight
MR angiography and susceptibility-wieghted imaging acquisition in assessing vascular injury due
to radiation therapy.
Figure 2. (a, e) TOF-MRA images, (b, f) TOF-MRA MIP-8 mm images, (c,
g) SWI images, and (d, h) SWI mIP-8
mm images, from original and MB-accelerated acquisitions. No visible aliasing
artifacts were observed with MB acceleration and overall image contrast was similar between
original and MB-accelerated images. CBMs were well visualized in SWI mIP-8 mm images,
as depicted by arrows.
Figure
4. SWI mIP-8 mm images focusing on four CMBs from two patient from original and
MB accelerated acquisitions were shown. The profiles over a line (with 5.9 mm
length) across the center of CMBs have similar patterns between the two
acquisitions, while the minimum signal levels were slightly higher with MB acceleration, possibility due
to an increased noise level.
