research Scalp Segmentation and Permanent Alopecia Prediction in Pediatric Craniospinal Irradiation: The PAST and HOPE Projects
In this retrospective study on pediatric craniospinal irradiation, researchers found that permanent radiation-induced alopecia occurred in 45.8% of patients, with higher radiation doses and treatment intensity being significant predictors, suggesting that defined dosimetric thresholds can support scalp-sparing planning.
