Pharmacokinetic modeling strategies for dynamic hyperpolarized urea imaging

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To evaluate pharmacokinetic modeling methods for quantification of tissue perfusion/permeability with hyperpolarized 13C urea. Methods Three models for quantitative analysis of dynamic HP urea imaging data were proposed and evaluated in numerical simulations and a thyroid cancer mouse model.

ASL 4D MRA Intracranial Vessel Segmentation With Deep Learning U‐Nets

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose a spatio‐temporal U‐Net based network (4DST) that exploits both spatial and dynamic information while avoiding memory‐intensive 4D convolutional layers for ASL‐based non‐contrast enhanced 4‐dimensional MR angiography (4D MRA) vessel segmentation.

Quantitative Susceptibility Mapping in Skull Base Chordoma: In Silico Analysis and In Vivo Application Towards Indirect Hypoxia Assessment

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate quantitative susceptibility mapping (QSM) beyond the brain through realistic simulations and to explore preliminary evidence that may be indicative of hypoxia in skull base chordomas (SBC). Methods Each step of the QSM pipeline was optimized within an in silico framework consisting of (i) phase unwrapping, (ii) background ...

31P MRSI Coil Combination Using 23Na Sensitivity Information

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To optimally combine receive channels for 31P MRSI when the SNR is relatively low using sensitivity maps obtained from 23Na signals. Methods This study utilized a dedicated X‐nuclei 15‐channel head coil array capable of imaging both 23Na and 31P.

Enhancing Selective Brain Cancer Therapy: Integrating Nanomedicine and Molecular Dynamics to Target the Cancerous Lipid Composition

Nano Select, EarlyView.
Improving selectivity within therapeutic design is critical to ensure targeted delivery to brain tumors. Targeting the cellular membrane composition distinctive of the blood–brain barrier and brain cancer cells is explored in this review. Nanomedicine can be utilized for precise tumor recognition, and detailed mechanistic interactions of therapeutics ...
