Delineation Information
- Modality
- CT
- Guideline
- Taken from Eekers DBP, Di Perri D, Roelofs E, Postma A, Dijkstra J, Ajithkumar T, et al. Update of the EPTN atlas for CT- and MR-based contouring in Neuro-Oncology. Radiother Oncol 2021;160:259–65. https://doi.org/10.1016/j.radonc.2021.05.013.
- Method
- Manual. The cochlea is a spiral structure (up to 0.6 cc) located in a bony cavity in the petrous portion of the temporal bone, caudal to the semicircular canals, lateral to the internal auditory canal. Using a WW/WL setting of 120/1500 on CT images, its volume can be defined as a small cavity.
