Single photon emission computed tomography (SPECT) is an imaging technique that widely used in medical diagnosis. This has never been applied to soils. The objective of this study was investigate the capabilities SPECT scanning for visualizing preferential flow soil. paper describes principle and its application tracer breakthroughs four large undisturbed soil columns (800‐mm length × 77‐mm diam.). new approach allows real‐time analysis patterns radioactive tracers 2‐D using planar imaging, 3‐D tomographic scanner. Not only does provide qualitative data, but it also quantification a tracer's spatial distribution. Our results characterized very clearly columns. opens up avenues studies porous media such as
