Computed diffusion-weighted imaging (cDWI) is the newly proposed method, and this technique has been applied recently. The application of MRI to lung cancer analysis has been a relatively recent development, and assessment by means of cDWI is also expected. The purpose of this study was therefore to directly and prospectively compare capabilities for pulmonary nodule/mass detection and differentiation of malignant from benign lesions among cDWI and really acquired DWI.
