Background and Purpose—Conventional contrast-enhanced angiography is the gold
standard for visualization of the vascular tree supplied by the major cerebral arteries and …

Purpose Noncontrast enhanced dynamic magnetic resonance angiography delineates the
pattern of dynamic blood flow of the cerebral vasculature. A model‐free solution was …

BACKGROUND AND PURPOSE: PCMR, widely used for the evaluation of blood flow, has
been adopted for the assessment of cerebrospinal fluid flow in a variety of disorders. The …

ABSTRACT BACKGROUND In the past, clinical decisions regarding treatment of
neurovascular disorders leading to ischemia have been guided by the percentage of …

Purpose A previously published cardiac‐gated 2D Qflow protocol at 7 T in cerebral
perforating arteries was optimized to reduce velocity underestimation and improve temporal …

Materials and Methods: The flow phantom has five types of acrylic pipes that represent
human blood vessels (inner diameters: 15, 12, 9, 6, and 3 mm). The pipes were fixed with …

Purpose: To compare measurements of blood flow velocity (BFV) and BFV changes in the
middle cerebral arteries (MCA) acquired from phase contrast magnetic resonance …

Purpose To visualize the hemodynamics of the intracranial arteries using time‐resolved
three‐dimensional phase‐contrast (PC)‐MRI (4D‐Flow). Materials and Methods MR …

Dynamic susceptibility contrast magnetic resonance imaging during bolus injection of
gadolinium contrast agent is commonly used to investigate cerebral hemodynamics. The …

Cerebrovascular reserve (CVR) is the potential for cerebral arteriolar dilatation to occur, in
response to decreased cerebral perfusion pressure, in order to maintain constant cerebral …
