dUTE positive contrast MRI images can be further improved using susceptibility-weighting information from the long echo phase image to enhance contrast and further suppress background to homogeneous near-zero values for the UTE-TE(2) difference image. In-vivo MR imaging of iron-labelled islet cells in the liver are used to illustrate the technique.
