The accurate assessment of the presence and extent of vascular disease, and planning of
vascular interventions based on MRA requires the determination of vessel dimensions. The …

BACKGROUND Magnetic resonance angiography (MRA) is the magnetic resonance
imaging of the blood vessels in the body. In MRA, Special pulse Sequences are used by an …

A 3D model‐based approach for quantification of vascular morphology from several MRA
acquisition protocols was evaluated. Accuracy, reproducibility, and influence of the image …

The software tools required for postprocessing of magnetic resonance (MR) angiograms
include the following functions: data handling, image visualization, and vascular analysis. A …

Purpose To describe and present some preliminary results for a novel algorithm for
segmentation with gray‐scale connectedness as a means to separate arteries and veins in …

Purpose: To evaluate the accuracy and precision of manual and automatic blood vessel
diameter measurements, a quantitative comparison was conducted, using both phantom …

Magnetic resonance imaging (MRI) is uniquely suited to study the pathophysiology of
arteriosclerosis. So far, magnetic resonance (MR) measurements of vessel dimensions have …

During the last decade, the quality of MR angiograms has risen substantially and their
clinical utility has been demonstrated progressively. This acceptance has created a need for …

Interpretation of magnetic resonance angiography (MRA) is problematic due to complexities
of vascular shape and to artifacts such as the partial volume effect. The authors present new …

Purpose To determine the appropriate image acquisition parameters for an accurate
measurement of vessel cross‐sectional area from MR angiography (MRA) images. Materials …
