In vascular malformation or tumor, diamagnetic materials including calcification and paramagnetic materials such as hemosiderin may appear in a same lesion. The knowledge about lesion composition is useful for understanding the cause of disease and making accurate diagnosis. However, this information is difficult to obtain using conventional MRI alone. In this study, we showed the feasibility of using quantitative susceptibility mapping to visualize diamagnetic materials inside paramagnetic lesions.
