UIC-2013-063 – Sample Interval Modulation Magnetic Resonance Elastography (SLIM-MRE)

Sampling Interval Modulation(SLIM)-MRE is an invention from UIC researchers that modulates existing Magnetic Resonance Elastography (MRE) to produce clearer images from the same source, 1.5 to 3 times faster. The images produced by classical MRE data are distorted due to misalignment throughout long observation acquisition times. This causes decreased accuracy of the images and compromised their readability. To solve this, UIC researchers created an innovative solution to decrease the time in which an image will be produced and improve their clarity. SLIM-MRE uses three spatial components of monofrequency tissue vibration simultaneously. Each spatial component uses different time discretization intervals and are modulated with various frequencies in the MR signal phase φ. This change results in clearer images, obtained 1.5 to 3 times faster, than the MRE images from the same temporally resolved MR phase images. Jonathan Gortat jgortat@otm.uic.edu (312) 413-1643
