Placement of a region of interest (ROI) for the calculation of relaxation time in the kidneyâs cortex. (a) In vivo T2*-weighted image of a single kidney post administration of SPION-labelled mMSCs, (b) placement of an ROI (yellow line) covering the cortex of the kidney where cell/SPION contrast is observed and (c) the changes in signal intensity as a function of echo time, with the solid line displaying the exponential fit of the data, from where the relaxation time is derived. Relaxation times were calculated with Paravision 6.0.1. (PDF 462âkb)
