There is increasing recognition of the importance of blood–brain barrier (BBB) disruption in
aging, dementia, stroke and multiple sclerosis in addition to more commonly-studied …

Perfusion is a fundamental biological function that refers to the delivery of oxygen and
nutrients to tissue by means of blood flow. Perfusion MRI is sensitive to microvasculature …

Neurovascular dysfunction, including blood–brain barrier (BBB) breakdown and cerebral
blood flow (CBF) dysregulation and reduction, are increasingly recognized to contribute to …

Dynamic susceptibility contrast magnetic resonance imaging (DSC‐MRI) is used to track the
first pass of an exogenous, paramagnetic, nondiffusible contrast agent through brain tissue …

Current clinical practice relies on clinical history to determine the time since stroke (TSS)
onset. Imaging-based determination of acute stroke onset time could provide critical …

The understanding of microvascular dysfunction without evidence of epicardial coronary
artery disease pales in comparison with that of obstructive epicardial coronary artery …

Chronic cerebral hypoperfusion (CCH) induces cognitive impairment, but the compensative
mechanism of cerebral blood flow (CBF) is not fully understood. The present study mainly …

Objectives To evaluate the efficiency of 2-and 3-class classification predictive tasks
constructed from radiomics features extracted from dynamic contrast-enhanced magnetic …

Background Dyspnea is common after COVID‐19. Though the underlying mechanisms are
largely unknown, lung perfusion abnormalities could contribute to lingering dyspnea …

Objectives To determine added value of permeability MRI in parotid tumor characterization
to T2-weighted imaging (T2WI), semi-quantitative analysis of time-intensity curve (TIC), and …
