FDG-PET/CT
can assess morphological and metabolic information at same time, and widely
utilized for N-stage assessment in non-small cell lung cancer (NSCLC)
patients. In the last decade, short
inversion time inversion recovery (STIR) turbo spin-echo (SE) imaging has
been determined at least as valuable as PET/CT in this setting. Recently, diffusion-weighted image (DWI) is
suggested as new technique for differentiation of metastatic lymph nodes from
non-metastatic lymph nodes. The
purpose of this study was to prospectively and directly compare capability of
N-stage assessment among integrated FDG-PET/CT, STIR turbo SE imaging and DWI
in NSCLC patients.
