Aims and objectives: In recent years, the field of head interventional radiology (Head IR) has made remarkable progress. In the past, Head IR was in a role to support and compensate for areas in which craniotomy by itself was insufficient in treating patients. However, along with dramatic evolution with medical devices [...]

Methods and materials: Methods Subjects were those who were exposed to a maximum ESD of more than 2Gy and the investigation period was set to be the 35 months between September 2013 and November 2016. The subjects were the 227 patients who had come for a follow-up at our hospital about two months after the Head IR procedu[...]

Results: The total hair loss rate was 32.1%. The higher the radiation dose the patients were exposed to, the higher were their hair loss rate (Table.2). 14.9% of patients who received less than 3Gy had hair loss. According to ICRP, the threshold dose value that would cause temporary hair loss is 3Gy, but a[...]

Conclusion: The condition in which hair loss has occurred with patients who were exposed to more than 2Gy of radiation due to receiving Head IR treatment was investigated. According to the ICRP, the threshold for triggering temporary hair loss from radiation exposure is 3Gy, but at our hospital, 14.9% of our p[...]
