The signal loss that occurs in regions of disturbed flow significantly decreases the clinical
usefulness of MR angiography in the imaging of diseased arteries. This signal loss is most …

Poststenotic flow patterns were analyzed in a flow phantom with a 1.5‐T magnetic
resonance (MR) imager, with use of different MR imaging and MR angiographic pulse …

Mechanisms of signal loss in magnetic resonance angiography were studied with a stenotic
flow phantom. The results indicate that while signal loss induced by mean fluid motions is …

Factors affecting blood vessel lumen definition for two‐dimensional and three‐dimensional
inflow magnetic resonance (MR) imaging methods are considered. Vessel definition is …

Objective: Signal loss due to poststenotic turbulence is one remaining limitation in the
clinical use of MRA. The objective of this study was to determine the factors influencing …

Time‐of‐flight magnetic resonance (MR) angiography is currently limited in the evaluation of
arterial stenoses by flowinduced signal loss. This signal loss has been attributed to phase …

Initial experimental and numerical analysis of artifacts due to pulsatile flow in two‐
dimensional time‐of‐flight (2D‐TOF) magnetic resonance (MR) angiography are presented …

A time-of-flight MRI velocity measurement technique is evaluated against corresponding
LDV measurements in a constriction tube model over a range of physiologic flow conditions …

A novel computer simulation technique is presented that allows the calculation of images
from Magnetic Resonance Angiography (MRA) studies of blood flow in realistic curving and …

Studies of flow in a 90%‐stenosis phantom were conducted to elucidate the parameters and
mechanisms responsible for signal loss in MR angiographic images. The studies …
