Observations of tissue reactions following neuroradiology interventional procedures

A study has been undertaken over a period of eight years of tissue reactions in interventional radiology patients receiving cumulative air kerma values to their scalp above 3 Gy. Patients receiving doses to the scalp above this trigger level have been followed up to determine when effects occur and to provide reassurance if they do. The study has shown that hair thinning and hair loss are the more likely effects and may occur in 50% of patients at dose above 4.5 Gy.
