RISChoice of In Vivo Versus Idealized Velocity Boundary Conditions Influences Physiologically Relevant Flow Patterns in a Subject-Specific Simulation of Flow in the Human Carotid Bifurcation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate fluid mechanics models are important tools for predicting the flow field in the carotid artery bifurcation and for understanding the relationship between hemodynamics and the initiation ...
Syringomyelia Hydrodynamics: An In Vitro Study Based on In Vivo Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simplified in vitro model of the spinal canal, based on in vivo magnetic resonance imaging, was used to examine the hydrodynamics of the human spinal cord and subarachnoid space with ...
A Left Ventricle Model to Predict Post-Revascularization Ejection Fraction Based on Cine Magnetic Resonance Images
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The left ventricular ejection fraction (LVEF) is an important clinical indicator of the cardiac function and long-term outcome for patients with coronary artery disease. A biomechanical model of ...
Spinal Subarachnoid Space Pressure Measurements in an In Vitro Spinal Stenosis Model: Implications on Syringomyelia Theories
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Full explanation for the pathogenesis of syringomyelia (SM), a neuropathology characterized by the formation of a cystic cavity (syrinx) in the spinal cord (SC), has not yet been provided. It ...
Effect of Inlet Velocity Profiles on Patient-Specific Computational Fluid Dynamics Simulations of the Carotid Bifurcation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Patient-specific computational fluid dynamics (CFD) is a powerful tool for researching the role of blood flow in disease processes. Modern clinical imaging technology such as MRI and CT can ...
Comparison of Particle Image Velocimetry and Phase Contrast MRI in a Patient-Specific Extracardiac Total Cavopulmonary Connection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particle image velocimetry (PIV) and phase contrast magnetic resonance imaging (PC-MRI) have not been compared in complex biofluid environments. Such analysis is particularly useful to investigate ...
