Representative delineation of MTV based on both the MTVst and MTVt contouring methods. Axial, sagittal, and coronal sections might not show the same node but rather different regions of disease in each anatomical section. (A-C) Axial, sagittal, and coronal scans of mediastinal disease contoured based on MTVst (magenta) and MTVt (blue) methods. (D) Axial view of left cervical neck disease contoured based on MTVst (magenta) and MTVt (green) methods. (E) Sagittal view of left cervical neck disease contoured based on MTVst (magenta) and MTVt (green) methods and mediastinal disease contoured based on MTVst (blue) and MTVt (pink) methods. (F) Coronal view of left cervical neck disease contoured based on MTVst (magenta) and MTVt (green) methods, mediastinal disease contoured based on MTVst (blue) and MTVt (pink) methods, left axillary disease contoured based on MTVst (yellow) and MTVt (brown) methods, and right cervical neck disease contoured based on MTVst (light blue) and MTVt (light green) methods.
