Interleaving Time and Structure.

Comput. Artif. Intell., 1998
A model for knowledge representation that incorporates structure and time is presented. The model is the domain of structured histories, which is based on the interleaving of these features in a nested, structured manner. A rich temporal representation language is provided.

SNR‐Efficient Inhomogeneous Magnetization Transfer (ihMT) for Clinical Applications at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Inhomogeneous MT (ihMT) is an MRI modality sensitive to Myelin, the lipid‐rich membrane surrounding the axons. A novel ihMT saturation strategy and its associated B1+$$ {\mathrm{B}}_1^{+} $$ correction at UHF are proposed. The aim is to generate a strong ihMT effect within a clinically compatible scan time while complying with SAR ...

Hemodynamic Modeling and Phase‐Adjustable Reconstruction of Hyperpolarized Cardiac 13C MRS Using 1H Cine and ECG Timing

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To deconvolve cardiac phase and hemodynamic effects in hyperpolarized (HP) [1‐13C]pyruvate and to develop a cardiac phase‐adjustable reconstruction framework. Methods Cardiac phase drift during dynamic acquisition of HP 13C MRS and its effect on dynamic signal fidelity were simulated using a digital cardiac phantom. A hemodynamic model

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Transverse Relaxation Time Constant of Cystathionine in Human Glioma at 3 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Cystathionine (Cth) has emerged as a promising biomarker for identifying 1p/19q codeleted gliomas. However, little is known about the T2 relaxation time constant of Cth in gliomas. The aim of this study was to measure the T2 of Cth in vivo in glioma and compare it to the T2s of other metabolites at 3 T.
