The clinical benefits of differentiation of anterior mediastinal solitary tumors is obvious, especially differentiation in clinical practice of tumors not needing further intervention or treatment and those needing them, as well as of malignant and other tumors. Many studies have reported that these tumors produce characteristic CT and MRI findings, but the differentiation is difficult in some cases. Recently, it has been suggested that diffusion-weighted imaging (DWI) could be useful for assessment of primary malignanct tumor. We hypothesized that DWI might be as effective as multi-detector row CT findings for the diagnosis and management of anterior mediastinal solitary tumors.
