Quantification of volume magnetic susceptibility of extracted gallbladder stones, with 28 different types of textures, was performed using quantitative susceptibility mapping. Both dia- and para-magnetic stones are seen and the susceptibility values were found to be comparable in magnitude to those found in venous vessels and blood products – and hence could be detected in-vivo using SWI. This is in agreement with a recent work reporting visualization of gall-stones using SWI.
