Magnetic resonance imaging observation of changes in water content during the drying and water absorption processes of a soil

Magnetic resonance imaging (MRI) is accepted as medical imaging technique capable of producing high quality images of the inside of the human body. MRI produces three-dimensional volume images of the internal structures using powerful magnets and radio waves, without any direct contact. We found that through the use of MRI, we were able to visualize changes in water contents in the soil samples during drying shrinkage and water absorption.
