Conventional MREIT suffers from long imaging time and
low phase sensitivity, potentially resulting in
inefficient conductivity estimation. Current-controlled
alternating SSFP-FID was proposed as an alternative to
achieve rapid encoding as well as high nonlinear phase
sensitivity. Nevertheless, since the nonlinear phase
model includes both tissue relaxation and Bz properties,
the former has to be known as a priori for conductivity
estimation, which requires multiple separate
acquisitions. In this work, we propose a novel,
current-controlled alternating reversed dual echo steady
state (DESS) MREIT for joint estimation of tissue
relaxation and electrical properties in a single
measurement.
