Particle Trace Visualization of Cardiac Flow Patterns using 3D Phase Contrast MRI: An in vitro Comparison with Streamlines Created using Dye
نویسندگان
چکیده
Introduction Intracardiac flow patterns can be visualized by particle traces obtained from three-dimensional phase contrast MRI. Good results have been shown for stationary [1] and time-resolved data [2]. New off-line retrospective gated 3D phase contrast techniques, providing high resolution time-resolved 3D velocity data, have improved the accuracy of the calculated particle traces [3]. While previous studies have investigated phase contrast MRI velocity measurements and particle path integration algorithms separately, this investigation is performed as a combined comparison with dye.

Evaluation of Elevated Mean Pulmonary Arterial Pressure Based on Magnetic Resonance 4D Velocity Mapping: Comparison of Visualization Techniques
PURPOSE Three-dimensional (3D) magnetic resonance phase contrast imaging (PC-MRI) allows non-invasive diagnosis of pulmonary hypertension (PH) and estimation of elevated mean pulmonary arterial pressure (mPAP) based on vortical motion of blood in the main pulmonary artery. The purpose of the present study was to compare the presence and duration of PH-associated vortices derived from different ...

BACKGROUND Phase-contrast MRI (PC MRI) can be used to assess blood flow dynamics noninvasively inside the human body. The acquired images can be reconstructed into flow vector fields. Traditionally, streamlines can be computed based on the vector fields to visualize flow patterns and particle trajectories. OBJECTIVES The traditional methods may give a false impression of precision, as they do...
متن کاملParticle Trace Visualization of Flow Patterns Downstream of a Prosthetic Aortic Valve in Patients
Introduction Late complications such as hemolysis and thrombus formation in patients with an implanted prosthetic heart valve have been related to fluid dynamic characteristics [ 11. Specific blood flow patterns such as flow reversal and vortex flow have been considered to contribute to thrombus formation [2]. In order to detect alterations of flow fields around prostheses in humans MR velocity...
متن کاملProbabilistic Flow Connectivity Mapping
Phase-Contrast (PC) MRI utilizes phase shifts resulting from moving spins to quantify tissue motion and blood flow. In cardio-vascular PC MRI applications, visualization techniques such as vector glyphs, streamlines, and particle traces are employed for depicting the flow situation. Whereas these techniques indeed provide useful information, they ignore the noise in the PC-MRI measurements and ...
