The authors describe their use of phase-contrast MRA to depict vascular anatomy and to
define the direction of blood flow. Documentation of flow reversal can provide information …

Magnetic resonance (MR) angiography constitutes a group of evolving MR imaging
techniques that can be used to directly image flow in arteries, veins, and cerebrospinal fluid …

PURPOSE To measure mean blood flow in individual cerebral arteries (carotid, basilar,
anterior cerebral, middle cerebral, and posterior cerebral) using a cine phase contrast MR …

We have assessed three-dimensional (3-D) phase-contrast (PC) MR angiography (MRA) in
the evaluation of extracranial (EC)—intracranial (IC) bypasses. This technique was …

Twenty-seven patients with 14 aneurysms and 17 vascular malformations were each
examined with both time-of-flight (TF) and phase-contrast (PC) magnetic resonance …

The interpretation of conventional spin-echo and gradient-echo MR images of intracranial
vascular lesions can be complex and ambiguous owing to variable effects on image …

Noninvasive MR acquisition of blood flow and stationary tissue provides three-dimensional
display of flow and of the vascular and brain surfaces. The calculated motion of a simulated …

A new acquisition scheme for three‐dimensional (3D) phase‐contrast MR angiography
reduces by 33% the measurement time for a data set sensitive to flow in all three orthogonal …

Cine phase‐contrast (PC) magnetic resonance (MR) pulse sequences have been used to
measure blood flow in a variety of vessels. Because the cine PC sequence is time …

Vessel flow quantification by two-dimensional (2D) phase-contrast magnetic resonance
imaging (PC-MRI) using a three-dimensional (3D) magnetic resonance angiography (MRA) …
