Guidelines
The guideline used is Hall WH, Guiou M, Lee NY, Dublin A, rayan S, Vijayakumar S, et al. Development and validation of a standardized method for contouring the brachial plexus: prelimiry dosimetric alysis among patients treated with IMRT for head-and-neck cancer. Int J Radiat Oncol Biol Phys 2008;72:1362–7. https://doi.org/10.1016/j.ijrobp.2008.03.004.
Method
Manual drawn using a brush of 5 mm diameter
Structure Boundaries
Cranial Boundary
The C5 vertebra is the cranial landmark
Caudal Boundary
The T2 vertebrae is the cranial landmark
Medial Boundary
Medially the contour extends upto the spil cord contour
Lateral Boundary
Laterally the contour should extend to the axilla upto the level where the axillary vessels seem to turn upwards
Ventral Boundary
In the neck region the scalenus anterior muscle is the anterior boundary and in the axillary region, the anterior or ventral boundary is the axillary artery.
Dorsal Boundary
In the cervical region, the scalenus medius is the dorsal or posterior boundary. Further laterally the dorsal boundary is formed by the rib (1st rib) and further laterally 5 mm behind the artery
