Delineation Information
- Modality
- CT
- Guideline
- PROPARA Trial Guidelines
- Method
- Delineated as a single structure from the level of the pylorus to the 4th part of the duodenum
Anatomical Boundaries
- Cranial
- At the level where the pylorus ends typically identified by presence of a thickening of the stomach wall or presence of an air bubble.
- Caudal
- At the level where the 4th part of the duodenum merges to the jejunum. This is typically marked by a constriction
- Medial
- Entire contour of the duodenum excluding the pancreas
- Lateral
- Entire contour of the duodenum
- Ventral
- Entire contour of the duodenum
- Dorsal
- Entire contour of the duodenum
