Accurate tumor staging is essential for choosing the appropriate treatment strategy in non-small cell lung cancer (NSCLC) patients. Recently, whole-body MRI without and with diffusion-weighted image (DWI) has been suggested as useful for assessment of distant metastases in oncology patients. However, no direct comparison of diagnostic accuracy for bone metastasis assessment has been made among whole-body MR imaging without and with DWI, bone scan and FDG-PET/CT in NSCLC patients. The purpose of this study was to prospectively and directly compare the capability for bone metastasis assessment whole-body MR imaging with and without DWI, integrated FDG-PET/CT and bone scan.
