In
Magnetic Resonance Electrical Impedance Tomography (MREIT), we measure
induced magnetic flux density subject to multiple injection currents to
reconstruct cross-sectional conductivity images. Newly developed multi-echo
pulse sequence in MREIT is expected to provide a higher magnitude image SNR
and lower noise level in magnetic flux density data. Injecting 3 mA imaging
currents into the human knee, we collected induced magnetic flux density data
using the multi-echo pulse sequence. Reconstructed conductivity images using
the harmonic Bz algorithm show good contrast among different parts of the
subcutaneous adipose tissue, muscle, synovial capsule, and bone inside the
knee
