Purpose: To determine the optimal saturation time (Tsat) that maximizes the CEST contrast between a reference and a target signal, such as normal versus pathological tissues or pre- versus post-contrast conditions. ...
The clinical utility of magnetic resonance elastography in differentiating tumor recurrence from pseudoprogression in glioblastoma [0.03%]
磁共振弹性成像在区分胶质母细胞瘤肿瘤复发与假性进展方面的临床应用价值
Richard Song,Lei Liu,Josephine Ofori-Apau et al.
Richard Song et al.
Glioblastoma (GBM) is the most common malignant primary brain tumor in adults with nearly universal progression despite aggressive treatment. Distinguishing true tumor recurrence from treatment-related effects (pseudoprogression) remains ch...
Repeatability of an MRI protocol for generating habitats based on cellularity, perfusion, and hypoxia in a murine model of glioma [0.03%]
基于细胞数、灌注和缺氧生成生态位的磁共振成像协议在胶质瘤小鼠模型中的重复性研究
Ayesha Das,David A Hormuth nd,Jack Virostko et al.
Ayesha Das et al.
Background: Hypoxia, cellularity, and vascularity are well-established as important drivers of tumor growth and treatment response. Diffusion weighted (DW-), dynamic contrast enhanced magnetic (DCE-), and oxygen enhanced ...
Association between CMR-derived pulmonary artery pulse wave velocity and pulmonary risk factors: the multi-ethnic study of atherosclerosis COPD study [0.03%]
基于CMR的肺动脉脉搏波速度与肺部风险因素之间的关系：动脉粥样硬化多元民族研究中的COPD研究
Roy Huurman,Eric Xie,Yoshiaki Ohyama et al.
Roy Huurman et al.
Purpose: Pulse wave velocity (PWV) is a quantitative marker of arterial stiffness which is widely validated in the systemic circulation. Pulmonary artery (PA) stiffness, as measured by PWV, and its associations with disea...
Systematic comparison of MPRAGE and BRAVO T1-weighted MRI pulse sequences and brain morphometry in high-risk young adults [0.03%]
高危青年成人中MPRAGE和BRAVO T1加权磁共振成像脉冲序列及脑形态学的系统比较
Mahmoud Elsayed,Carly McIntyre-Wood,Kyla L Belisario et al.
Mahmoud Elsayed et al.
Structural MRI is widely used in psychiatric research to investigate brain morphometry, but variability in acquisition methods may influence the reproducibility of findings. In particular, differences between commonly used T1-weighted seque...
Foot dynamic contrast-enhanced MRI for assessing microcirculatory changes after endovascular therapy in peripheral artery disease: A prospective pilot study [0.03%]
外周动脉疾病血管内治疗后足部动态磁共振对比增强在评估微循环变化中的作用：一项前瞻性试点研究
Keqian Zhou,Cong Chen,Sha Du et al.
Keqian Zhou et al.
Background: Peripheral artery disease (PAD) impairs foot perfusion, whereas successful restoration of macroscopic arterial patency does not necessarily indicate normalization of distal foot microcirculation. ...
Reconstruction of MRI from undersampled k-spaces of double-contrast volume acquisitions using deep neural networks [0.03%]
