Abstract: A customized computer program (MRIView) is described for visualizing and quantifying complex blood flow patterns in major vessels, using nongated and cardiac-gated three-dimensional (3D) velocity data obtained with MR velocity-encoded phase pulse sequences. Streamlines, arrows, and particle paths (collectively referred to as "paths") can be computed interactively, using both forward and backward time integration of the velocity field. The program provides interactive cross-sectional and 3D perspective visualiz… Show more

“…6a. In this case, previously reported methods relying on in-plane velocity measurements and evaluation of PWV along a vessel centerline (29)(30)(31)(32)(33)(34) are no longer applicable. Note also that the complex aortic shape and in particular the sharp bending of the distal descending aorta in this patient (see Fig.…”

“…Recently, more comprehensive three-dimensional (3D) CINE techniques in combination with three-directionally encoded velocities (flow-sensitive four-dimensional [4D] MRI) have been reported that provide information on multidirectional in vivo blood flow with full volumetric coverage of the vessel of interest (29)(30)(31)(32)(33)(34). It was the purpose of this study to investigate if PWV can be reliably estimated from 3D CINE PC data despite its lower temporal resolution by exploiting its full volumetric coverage.…”

“…However, the visualization becomes more complex for three-dimensional expansion and less straightforward than its two-dimensional counterpart. A visualization technique using streamlines, arrows, and particle paths developed by Buonocore (22) for cardiac imaging might also be promising to visualize the CSF flow patterns.…”

“…Recently, improved time-resolved (CINE) 3D PC MRI techniques using electrocardiography (ECG) gating and advanced navigator respiration control (flow-sensitive four-dimensional [4D] MRI) have been successfully applied for the analysis of pulsatile 3D blood flow in the aorta (14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24). Such techniques offer the opportunity for the detailed analysis of pulsatile 3D blood flow but require scan times up to 20 min.…”

“…3). Flow visualization was performed using 3D stream lines, which resemble traces tangential to the measured velocity vector field for a given time frame within the cardiac cycle (14,17). The origin of individual stream lines was manually defined by interactively positioning a regular grid with a given number emitter points in the thoracic aortic lumen.…”
