SYSTEMS AND METHODS FOR LOW FIELD MAGNETIC RESONANCE ELASTOGRAPHY

摘要

Systems and methods for performing a medical imaging process are provided. In some aspects, a method includes arranging a subject in a low-field magnetic resonance imaging (LFMRI) system configured to generate a static magnetic field about at least a region of interest (ROI) of the subject comprising materials capable of producing magnetic susceptibility artifacts, and controlling the LFMRI system to perform a pulse sequence to acquire magnetic resonance elastography (MRE) data from the subject. The method also includes performing, during the pulse sequence, electron spin resonance (ESR) pulses to enhance signals associated with the MRE data, and reconstructing, using the MRE data, at least one image indicative of mechanical properties of tissues in the subject.
