Abstract
A magnetic resonance method and device for characterizing the pattern of flow of a flowing fluid including the steps of flowing the fluid through a conduit, wherein a segment of the conduit defines a measurement volume, subjecting the flowing fluid in the measurement volume to a magnetic field gradient generally in the direction of flow of the fluid, wherein the magnetic field gradient in the direction of flow comprises a generally fixed value in the measurement volume, and a magnetic resonance pulse, acquiring at least one odd echo from the magnetic resonance pulse, wherein the echo comprises signals from streamlines in the flowing fluid in the measurement volume, processing the signals to determine a flow behaviour index for the flowing fluid, determining an average velocity of the flowing fluid, and calculating velocity as a function of the radius of the conduit using the flow behaviour index and the average velocity and relating the function to a pattern of flow to characterize the pattern of flow exhibited by the flowing fluid.
