Computational Simulation of Magnetic Resonance Imaging Techniques for Velocity Field Measurements
A procedure to simulate the measurement of ow velocity components using magnetic resonance imaging (MRI) techniques is described. This procedure combines a numerical solution of the (Bloch) equations for owing spins, with a CFD solution for the velocity eld. The solution of the Bloch equations, (based on a hybrid Eulerian-Lagrangian particle-in-cell approach), is applied to test problems in 1,2...
متن کاملComparison of velocity vector imaging echocardiography with magnetic resonance imaging in mouse models of cardiomyopathy.
BACKGROUND Myocardial strain imaging using echocardiography can be a cost-effective method to quantify ventricular wall motion objectively, but few studies have compared strain measured with echocardiography against magnetic resonance imaging (MRI) in small animals. METHODS AND RESULTS We compared circumferential strain (CS) and radial strain (RS) measured with echocardiography (velocity vect...
متن کاملDiastolic dysfunction in patients with preserved ejection fraction: identification by velocity encoded magnetic resonance imaging
Introduction Diastolic dysfunction was recently recognized as an important cause for heart failure in patients with preserved ejection fraction. Diastolic dysfunction is typically assessed in clinical routine using transmitral and pulmonary-venous flow characteristics by Doppler-echocardiography. We hypothesized that VENC-MRI has a similar ability to identify patients with diastolic dysfunction...
متن کاملVelocity Measurements in Capillaries
A new velocimeter for measurements in microscopic regions is presented. A common charge coupled device (CCD) has been used as spatial filter for one-component velocity measurements. The characteristics of this sensor are investigated and first application results presented.
