Finding the ideal IDEAL acquisition scheme for multi-echo UTE imaging

چکیده
(top to bottom) 3-, 4and 5-echo bipolar acquisitions with an optimum marked; high NSA aids estimation; dot-dash line is an example hardware speed constraint (depends upon FOV and resolution); dash line is an example scan time constraint; maps computed with independent Δ3,4 show similar results Fig. 2: Strategies to acquire multiecho UTE images in 1 TR; echo spacings (Δ1, etc.) affect estimates of water, fat & short-T2 anatomy Fig. 1: Axial knee image w/ typical UTE contrast

Improved Radial Spoiled Gradient Echo Imaging with Randomized RF Phases and Gradient Moments
Introduction Radiofrequency (RF) spoiling is the most established spoiling method for gradient echo imaging. It is based on a quadratic variation of RF (and receiver) phase angles in successive TRs, coupled with a constant gradient moment at the end of each TR period to create a range of resonance offset angles within each imaging voxel (1). However, it was recognized that RF spoiling yields no...

متن کاملUltrashort TE Imaging with Rescaled Digital Subtraction (UTE RDS)
INTRODUCTION Imaging of short T2 tissues often requires not only a short TE so that signal from very short T2 species can be detected, but efficient suppression of the signal from surrounding long T2 species which may have much higher MR signals (1-4). There are three major long T2 suppression techniques: 1) A long 90° pulse followed by gradient spoiling to selectively saturate long T2 species ...
متن کاملA Multi-echo Acquisition Method with Reduced Echo Spacing for Robust IDEAL Water-Fat Decomposition at 3T
images from 6-pt IDEAL reconstruction, and the R2* map (c) from 6-pt T2*-IDEAL reconstruction. The echo spacing was 1.3ms (1.1π). Uniform water-fat decomposition was achieved. Figure 1 (left): IDEAL cost functions for two sets of echo times. The purpose of the IDEAL iteration is to search for the minimum (0Hz in this example) of the cost function curves. To avoid converging to local minima, the...
متن کاملCardiac 4D phase-contrast CMR at 9.4 T using self-gated ultra-short echo time (UTE) imaging
BACKGROUND Time resolved 4D phase contrast (PC) cardiovascular magnetic resonance (CMR) in mice is challenging due to long scan times, small animal ECG-gating and the rapid blood flow and cardiac motion of small rodents. To overcome several of these technical challenges we implemented a retrospectively self-gated 4D PC radial ultra-short echo-time (UTE) acquisition scheme and assessed its perfo...
