Ionizing Radiation in Craniofacial Surgery: A Primer on Dose and Risks

Area of Science:

• Medical Physics
• Pediatric Radiology
• Craniofacial Surgery

Background:

• Responsible ordering of radiological imaging requires understanding radiation dose and patient risk.
• Children are more vulnerable to radiation effects due to radiosensitivity and longer lifetime exposure.
• Fluoroscopy and computed tomography are common in craniofacial surgery, but dose reports are often incomparable, obscuring patient risk.

Purpose of the Study:

• To present the fundamentals of radiation, dose, and risk in radiological imaging.
• To introduce a low-dose craniofacial computed tomography protocol for pediatric patients.

Main Methods:

• Review of radiation physics principles.
• Explanation of radiation dose metrics and risk assessment.
• Description of a novel low-dose craniofacial CT protocol.

Main Results:

• Established foundational knowledge of radiation dose and risk.
• Introduced a practical low-dose CT protocol for craniofacial imaging.
• Aimed to improve the comparability of dose reports and clarify patient risk.

Conclusions:

• Understanding radiation dose and risk is paramount for responsible medical imaging, especially in pediatrics.
• The proposed low-dose protocol offers a method to mitigate risks associated with craniofacial CT.
• Standardizing dose reporting and risk assessment is crucial for patient safety in pediatric radiology.
