Numerical Simulation of Bloch Equations for Dynamic Magnetic Resonance Imaging

Abstract

Mean and standard deviation velocities and Re based on the mean velocity for diferent operating voltages of the Ćow pump at temperature 16 • C (kinematic viscosity ν = 1.1092 × 10 −2 cm 2 /s [137]). . . . . . . . . and magnetic gradient Ąelds. Altering this pattern, which is commonly known as a MRI pulse sequence, it is possible to exploit a wide range of contrast mechanisms including access to physiological functions such as difusion, Ćow, blood oxygenation, cellular metabolism and tissue temperature. Therefore, MRI is not restricted to a qualitative description of anatomy, but also serves as a powerful tool for interventional, functional, metabolic and quantitative studies, which have a huge signiĄcance in diagnostic imaging.
