Jabrane Karkouri,Masha Novoselova,Sarah Miller et al.
Jabrane Karkouri et al.
Purpose: We present a method for absolute quantification of deuterated metabolites in vivo at 7T. We describe acquisition protocols and an analysis pipeline compatible with 7T Terra MRIs. We apply them using a 2H/1H recei...
Clinically Feasible White Matter Fiber Tractography in Peritumoral Zones With Cerebral Vasogenic Edema [0.03%]
脑肿瘤周圍区室间孔周围白质束纤维经脉追踪的临床可行性研究
Patryk Filipiak,Timothy M Shepherd,Kamri Clarke et al.
Patryk Filipiak et al.
Purpose: In diffusion MRI, vasogenic edema manifests as a major fraction of isotropic water that dilutes the anisotropic intra-axonal portion of the signal. Many tractography algorithms mistake vasogenic edema for the whi...
Yonatan Urman,Zachary Shah,Ashwin Kumar et al.
Yonatan Urman et al.
Purpose: To accelerate MRI acquisition by incorporating the previous scans of a subject during reconstruction. Although longitudinal imaging constitutes much of clinical MRI, leveraging previous scans is challenging due t...

Joel Jose Quitlong Nario,Victor Murray,Anthony Mekhanik et al.
Joel Jose Quitlong Nario et al.
Purpose: To develop a deep learning-based auto-navigation technique for free-breathing golden-angle radial MRI named RANGR (Respiratory Auto-Navigator for Golden-angle Radial free-breathing abdominal MRI). ...
Tissue Strain Mapping via Magnetic Resonance Elastography Can Be Used to Detect Active Lesion Expansion [0.03%]
基于磁共振弹性成像的组织形变场建模及活动病灶检测研究
Ziying Yin,David S Lake,Armando Manduca et al.
Ziying Yin et al.
Purpose: Active lesion expansion is clinically important because it can indicate disease progression and influence management and treatment planning. However, sequential imaging is often unavailable, and rapid growth can ...
Simultaneous Cerebral Blood Flow and Cerebrovascular Reactivity Obtained From Novel Multi-Band Multi-Echo Pseudo-Continuous Arterial Spin Labeling (M2-PCASL) Sequence: A Test-Retest Reliability Study [0.03%]
基于新型多带多回波伪连续动脉自旋标记(M2-PCASL)序列同时获取脑血流和脑血管反应性的测试-重测信度研究
Jody Todd,Maria-Julieta Mateos,Ibraheem Budeir et al.
Jody Todd et al.
Purpose: We aim to assess the reliability of cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) obtained simultaneously from a novel multi-band pseudo-continuous arterial spin labeling (M2-PCASL) sequence and ...
Oliver Schad,Julius Frederik Heidenreich,Nils Petri et al.
Oliver Schad et al.
Purpose: Real-time imaging of cardiac function is favorable due to shorter scan times and becomes necessary when arrhythmia or inability to hold breath leads to insufficient quality of electrocardiogram (ECG)-gated Cartes...
Stefan Popescu,Thomas Allmendinger,Reut Reina et al.
Stefan Popescu et al.
Purpose: To empower MR scientists and clinicians to produce customized, high-definition anthropomorphic MRI phantoms directly from patient or volunteer DICOM images using commercially available 3D printers and printing ma...
