PURPOSE We compared three-dimensional time-of-flight MR angiograms obtained before
and after acetazolamide administration to evaluate whether use of this drug could improve …

BACKGROUND AND PURPOSE: The spatial resolution of 3D time-of-flight MR angiography
(TOF-MRA) can be improved within a reasonable examination time by combining 3T and …

The signal-to-noise ratio obtained from arteries in three-dimensional (3D) time-of-flight (TOF)
magnetic resonance (MR) angiography is often too low to allow clinical diagnosis because …

To evaluate the accuracy of 3-dimensional time-of-flight magnetic resonance angiography
(3D TOF MRA) for detecting intracranial arterial occlusive disease, this technique was …

Background Three-dimensional (3D) time-of-flight (TOF) MR angiography (MRA) at 7 T has
been reported to have high image quality for visualizing small perforating vessels. However …

Purpose To establish the feasibility of intracranial time‐of‐flight (TOF) MR angiography
(MRA) at 7T using phased array coils and to compare its performance to 3T. Materials and …

Purpose: We sought to prospectively evaluate the image quality and visualization of the
intracranial arteries using high spatial resolution contrast-enhanced magnetic resonance …

Objectives: Magnetic resonance angiography (MRA) is noninvasive and does not require
the application of high doses of contrast agents, and thus is used in the clinical routine for …

Intracranial three-dimensional time-of-flight (TOF) magnetic resonance (MR) angiography
was performed in seven healthy volunteers and eight patients with both 1.5-T and 3.0-T MR …

The saturation phenomenon that limits vessel visibility in unenhanced time-of-flight MR
angiograms can be overcome by the injection of MR contrast agents that shorten the T1 of …
