Reverberant magnetic resonance elastography

Abstract

This study explores reverberant shear wave elastography to create accurate magnetic resonance elastograms. The reverberant elastography technique utilizes the complex wave field originating from multiple point sources or reflected from various angles and superimposed with each other. The study was conducted on a calibrated brain phantom. Results showed that reverberant elastography produced accurate elastograms with an accuracy range of 84-97% and contrast-to-noise ratios of 24 dB, compared to an accuracy range of 86-97.7% and contrast-to-noise ratios of 25 dB for the established subzone inversion method.
