Delineation Information
- Modality
- MR
- 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 pineal gland is a small endocrine gland measuring approximately 8 mm in diameter and notably involved in the regulation of the sleep-wake cycle. Co-registration with T1-weighted MRI is recommended for
delineation.
Anatomical Boundaries
- Cranial
- It is located posteriorly to the third ventricle
- Caudal
- Anteriorly to the ampulla of Galen.
- Lateral
- Inferiorly to the splenium of the corpus callosum
