Fast Submillimeter QSM for Simultaneous QSM/MRSI of the Brain at 7T

ISMRM Annual Meeting
The feasibility of simultaneous QSM and MRSI has been recently demonstrated using SPICE. But the resolution of QSM obtained by SPICE at 7T is limited to only 3 mm due to bandwidth requirements. To overcome the resolution limitation, this work proposes a fast acquisition sequence for high-resolution encoding, and a model-based method to reconstruct from

Parallel hashing algorithms on BSP and QSM models

18th International Parallel and Distributed Processing Symposium, 2004. Proceedings., 2004
Summary form only given. We study two parallel computing models - the bulk synchronous parallel (BSP) and the queued shared memory (QSM) - as alternatives to the PRAM model to provide more accurate performance predictions and analyses, and compares the two models in detail. As a case study, we consider a simple hashing problem, design the two versions -

Realistic Abdominal QSM phantom

ISMRM Annual Meeting
Abdominal Quantitative Susceptibility Mapping (QSM) involves a series of additional challenges compared with brain QSM, mainly because of the presence of undesired contributions related to fat and gasses. Previously, we proposed a QSM phantom with fat contributions, which emulated different susceptibility scenarios in the abdominal region. In this work,

Experimental evaluation of QSM, a simple shared-memory model

Proceedings 13th International Parallel Processing Symposium and 10th Symposium on Parallel and Distributed Processing. IPPS/SPDP 1999, 2003
Parallel programming models should attempt to satisfy two conflicting goals. On one hand, they should hide architectural details so that algorithm designers can write simple, portable programs. On the other hand, models must expose architectural details so that designers can evaluate and optimize the performance of their algorithms.

Computationally efficient multi-echo QSM

ISMRM Annual Meeting
With increasingly popular multi-echo QSM, the combination of echoes becomes important in terms of accuracy, SNR and computation time. We compared 6 different pipelines with quantitative and Laplacian unwrapping and three different echo combination approaches, weighted averaging of QSMs, combination of the phase, and non-linear fitting.

Automated QSM Processing in Multiple Sclerosis

ISMRM Annual Meeting
In this work, an automated and scalable processing tool for Quantitative Susceptibility Mapping (QSM), QSMxT, is applied to a large dataset of 3D echo-planar imaging (3D-EPI) acquisitions of Multiple Sclerosis (MS) patients and volunteer controls. This is used to reconstruct QSMs for all subjects and generate a group space for the study. MS lesions are
