Ultra-high
spatial resolution compressed sense Tri-TSE, with threefold acceleration, does
not negatively impact the accuracy of MS-qMRI maps of PD, T1, and T2. Tissue pixel
values show good quantitative agreement with the literature and non-compressed
sense Tri-TSE equivalents.
Comparison
of directly acquired image quality. A) Non-CS Tri-TSE and B) CS Tri-TSE images
are shown with PD-, T2-, and T1-weighted acquisitions from left to right.
Whole-brain
histogram comparison. The CS-Tri-TSE images have less vulnerability to flow
ghosting artifacts, which probably lead to tighter PD, T1, and T2 histograms
(CS in blue and non-CS in gray).
