Representative delineation of MTV based on both the MTV_st and MTV_t 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 MTV_st (magenta) and MTV_t (blue) methods. (D) Axial view of left cervical neck disease contoured based on MTV_st (magenta) and MTV_t (green) methods. (E) Sagittal view of left cervical neck disease contoured based on MTV_st (magenta) and MTV_t (green) methods and mediastinal disease contoured based on MTV_st (blue) and MTV_t (pink) methods. (F) Coronal view of left cervical neck disease contoured based on MTV_st (magenta) and MTV_t (green) methods, mediastinal disease contoured based on MTV_st (blue) and MTV_t (pink) methods, left axillary disease contoured based on MTV_st (yellow) and MTV_t (brown) methods, and right cervical neck disease contoured based on MTV_st (light blue) and MTV_t (light green) methods.
