Recently, image quality and diagnostic capability of chest MR imaging have been improving and chest DWI were reported the utility of diagnosis of solitary pulmonary nodules (SPNs) including lung cancer. Under these circumstances, it is important that comparisons of methods for evaluating SPNs differentiation and selecting b values result in useful contributions to clinical practice. The purpose of this study was to determine the appropriate parameters and evaluation method for quantitative differentiation of SPNs by means of DWI.
