Abstract

Rapid quantitative evaluations of heart function are carried out with strain measurements from Magnetic Resonance Imaging (MRI) images using a circuit at least partially on board or in communication with an MRI Scanner and in communication with the at least one display, the circuit including at least one processor that: obtains a plurality of series of MRI images of long and short axis planes of aheart of a patient, with each series of the MRI images is taken over a different single beat of the heart of the patient during an image session that is five minutes or less of active scan time and with the patient in a bore of the MRI Scanner; measures strain of myocardial heart tissue of the heart of the patient based on the plurality of series of MRI images of the heart of the patient; and generates longitudinal and circumferential heart models with a plurality of adjacent compartments, wherein the compartments are color-coded based on the measured strain.
