Parasternal lymphoscintigraphy as an aid in radiation treatment planning.
Depth and position of the parasternal lymph glands are determined by scintigraphy in 67 patients treated by radiotherapy for breast carcinoma. The average depth is found to be 28 mm, and the average position 27 mm laterally from the median line. However, the variation in individual patients as well as between different patients is so great that individual measurements must be deemed essential for adequate radiotherapy, especially when electrons are used for treatment.
