Quantification of myocardial perfusion MRI using radial data acquisition: comparison of Ktrans from dual-bolus and T1 estimation methods [PDF]

Journal of Cardiovascular Magnetic Resonance, 2010
Introduction Myocardial perfusion MRI is a useful modality to detect myocardial ischemia. Quantitative perfusion estimates require an accurate arterial input function (AIF). Recently, a method for estimating T1 and thus gadolinium concentration from a radial k-space perfusion sequence was proposed [1].

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Validation of Dynamic Contrast-Enhanced Magnetic Resonance Imaging-Derived Vascular Permeability Measurements Using Quantitative Autoradiography in the RG2 Rat Brain Tumor Model

Neoplasia: An International Journal for Oncology Research, 2007
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is widely used to evaluate tumor permeability, yet measurements have not been directly validated in brain tumors.

Dual p‐n Heterojunction and Photothermal Conversion Synergy Endows NiFe‐LDH/CoS/BiVO4 Photoanodes With Enhanced Photoelectrocatalytic Performance

Carbon Energy, EarlyView.
A novel p‑n heterojunction NiFe‑LDH/CoS cocatalyst is rationally assembled on BiVO4 to yield dual p‐n heterojunction photoanodes. Benefiting from the intrinsic photothermal effect of CoS, the obtained NiFe‐LDH/CoS/BiVO4 photoanodes accelerate interfacial charge separation and transportation, optimizes sluggish surface OER kinetics, and achieves ...

Do cerebral blood volume and contrast transfer coefficient predict prognosis in human glioma?

, 2006
INTRODUCTION: Noninvasive measurements of cerebral blood volume (CBV) and contrast transfer coefficient (Ktrans) have potential benefits in the diagnosis and therapeutic management of adult glioma. This study examines the relationship between CBV, Ktrans,

Prognostic Value of Combined FDG PET and MRI Analysis of Cervical Cancer: A Systematic Review and Meta‐Analysis

Journal of Medical Radiation Sciences, EarlyView.
This systematic review and meta‐analysis synthesised FDG PET/MRWE biomarkers in cervical cancer, including a pooled analysis of the association between metabolic activity (SUV‐based metrics) and tumour diffusion characteristics (ADC measures). Prognostic evidence from the included studies was also analysed to identify PET‐ and MRI‐based parameters, as ...

Non‐Rigid Motion‐Compensated MR Multitasking for Free‐Breathing Low‐Dose Dynamic Contrast‐Enhanced MRI in the Abdomen

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve free‐breathing low‐dose quantitative dynamic contrast‐enhanced (DCE) MRI for imaging pancreatic ductal adenocarcinoma. Methods We introduced non‐rigid (NR) motion compensation (MoCo) into MR Multitasking using a novel “in‐subspace” formulation that directly applies motion fields to spatial feature maps (eigenimages ...
