A unified model for reconstruction and R2* mapping of accelerated 7T data using the quantitative recurrent inference machine

Autor: Chaoping Zhang, Dimitrios Karkalousos, Pierre-Louis Bazin, Bram F. Coolen, Hugo Vrenken, Jan-Jakob Sonke, Birte U. Forstmann, Dirk H.J. Poot, Matthan W.A. Caan

Publikováno v: NeuroImage, Vol 264, Iss , Pp 119680- (2022)

Quantitative MRI (qMRI) acquired at the ultra-high field of 7 Tesla has been used in visualizing and analyzing subcortical structures. qMRI relies on the acquisition of multiple images with different scan settings, leading to extended scanning times.

Evaluation of HIF-1α Expression in a Rat Glioma Model Using Intravoxel Incoherent Motion and R2* Mapping

Autor: Dongdong Wang, Yiping Lu, Xuanxuan Li, Nan Mei, Pu-Yeh Wu, Daoying Geng, Hao Wu, Bo Yin

Publikováno v: Frontiers in Oncology, Vol 12 (2022)

Accurate evaluation of HIF-1α levels can facilitate the detection of hypoxia niches in glioma and treatment decisions. To investigate the feasibility of intravoxel incoherent motion (IVIM) and R2* Mapping for detecting HIF-1α expression levels, six

Cascade of Denoising and Mapping Neural Networks for MRI R2* Relaxometry of Iron-Loaded Liver

Autor: Qiqi Lu, Changqing Wang, Zifeng Lian, Xinyuan Zhang, Wei Yang, Qianjin Feng, Yanqiu Feng

Publikováno v: Bioengineering, Vol 10, Iss 2, p 209 (2023)

MRI of effective transverse relaxation rate (R2*) measurement is a reliable method for liver iron concentration quantification. However, R2* mapping can be degraded by noise, especially in the case of iron overload. This study aimed to develop a deep

Multi-centre, multi-vendor reproducibility of 7T QSM and R2* in the human brain: Results from the UK7T study

Autor: Catarina Rua, William T. Clarke, Ian D. Driver, Olivier Mougin, Andrew T. Morgan, Stuart Clare, Susan Francis, Keith W. Muir, Richard G. Wise, T. Adrian Carpenter, Guy B. Williams, James B. Rowe, Richard Bowtell, Christopher T. Rodgers

Publikováno v: NeuroImage, Vol 223, Iss , Pp 117358- (2020)

Introduction: We present the reliability of ultra-high field T2* MRI at 7T, as part of the UK7T Network's “Travelling Heads” study. T2*-weighted MRI images can be processed to produce quantitative susceptibility maps (QSM) and R2* maps. These ref

Publikováno v: NeuroImage, Vol 222, Iss , Pp 117216- (2020)

Susceptibility weighted magnetic resonance imaging (MRI) is sensitive to the local concentration of iron and myelin. Here, we describe a robust image processing pipeline for quantitative susceptibility mapping (QSM) and R2* mapping of fixed post-mort
