A spin-echo sequence with very short echo-time (TE = 2 ms) has been designed to measure moisture content inside highly hygroscopic materials and was able to detect moisture even at very low moisture content (6%). In order to enhance the spinlattice relaxation process, and thus reduce the total scanning time of an image, the pulp samples were wetted with solutions containing contrasting agents such as copper sulphate. The optimized value of the copper sulphate concentration was finally found to be around 0.5 gL-1. A calibration curve was utilized to transform the signal intensity into moisture content values. A slight curvature probably due to shrinkage effects appears in the calibration curve.
