In quantitative susceptibility mapping (QSM), it is impossible to define an absolute reference for the reconstructed susceptibility values. Therefore, it has been suggested to use a relative reference, such as the mean susceptibility within...
The Pulseq-CEST Library: definition of preparations and simulations, example data, and example evaluations [0.03%]

Over the past two decades, ultra-high field (UHF) magnetic resonance imaging (MRI) has evolved from pure investigational devices to now systems with CE and FDA clearance for clinical use. UHF MRI offers enhanced diagnostic value, especially...
Synthetic DWI: contrast improvement for diffusion-weighted imaging in prostate using T1 shine-through by synthesizing images with adjusted TR and TE [0.03%]
合成DWI：通过合成调整了TR和TE的图像来改善前列腺扩散加权成像的T1透亮对比度
Yu Ueda,Tsutomu Tamada,Atsushi Higaki et al.
Yu Ueda et al.
Objective: To investigate whether synthetic DWI (SyDWI) calculated with short TR and zero TE can improve diffusion contrast in prostate compared to conventional DWI acquired with standard TR and TE. ...
Assessing measurement consistency of a diffusion tensor imaging (DTI) quality control (QC) anisotropy phantom [0.03%]
弥散张量成像(DTI)质量控制(QC)各向异性模型的测量一致性的评估

Ségolène Dega,Mónica Ferreira,Marten Veldmann et al.
Ségolène Dega et al.
Objective: Accurate estimation of brain myelin-water content from multi-echo data is challenging due to the inherent ill-posedness of the inversion problem. In this study, we propose a novel method for myelin-water imagin...
