Assessment of N-stage is very important for management in non-small cell lung cancer (NSCLC) patients. Recently, STIR turbo spin-echo (SE) imaging is suggested as useful for N-stage assessment in NSCLC patients. On the other hand, diffusion-weighted image (DWI) has been suggested as useful for determination of nodal and distant metastases in oncology patients. However, no direct comparison of capability for N-stage assessment has been made between these two methods in NSCLC patients. The purpose of this study was to directly compare diagnostic capability of lymph node metastases between STIR turbo SE imaging and DWI in NSCLC patients.
