Recently, image quality and diagnostic capability of chest MR imaging have been improving and STIR sequence was reported the utility of detection and diagnosis of lung cancer as well as thin-section MDCT. In addition, it has been suggested that diffusion-weighted imaging (DWI) could be useful for assessment of primary malignancy including lung cancer. We hypothesized that DWI was useful sequence for the detection and the subtype classification of pulmonary adenocarcinomas. The purpose of this study was to compare the capabilities for detection and subtype classification in patients with pulmonary adenocarcinoma between DWI and STIR.
