- Primary Outcome Measures
Name Time Method 1.To determine the cut-off standardized uptake value (SUV) on 18F fluoro-2-deoxy-glucose (FDG) positron emission tomography/computed tomography (FDG-PET/CT) images that correlates best with pathologic gross tumor volume (GTVpath) for nonâ??small-cell lung cancer (NSCLC) by various (semi) automated delineation methods, to compare CT based visual assessment with pathology.Timepoint: NI
- Secondary Outcome Measures
Name Time Method 1 compare differences in tumor volume as delineated by various semiautomated methods and corresponding data obtained on pathological specimen and to quantify the magnitude of difference <br/ ><br>2 Determine interobserver variability between observers in auto-contourâ??based delineation in the delineation of the GTV and manual PET-CTâ??based delineation in patients with untreated NSCLC. <br/ ><br>3.Validation of the obtained results of one best fit method on subsequent 15 patients in validation group <br/ ><br>Timepoint: NI
