Delineation Information
- Modality
- CT
- Guideline
- The guideline used is Brouwer CL, Steenbakkers RJHM, Bourhis J, Budach W, Grau C, Grégoire V, et al. CT-based delineation of organs at risk in the head and neck region: DAHANCA, EORTC, GORTEC, HKNPCSG, NCIC CTG, NCRI, NRG Oncology and TROG consensus guidelines. Radiother Oncol 2015;117:83– 90. https://doi.org/10.1016/j.radonc.2015.07.041. The gland is typically enhancing due to the high iodine content and has two lobes joined by a central isthmus
- Method
- Manual
