Track 37: Radiation Dose Optimization and Safety

Radiation Dose Optimization and Safety

Radiation dose optimization and safety are vital in medical imaging to protect patients, staff, and the environment while ensuring high-quality diagnostic results. The focus is on minimizing exposure without compromising the accuracy of imaging.

Key Principles

1. Justification of Imaging

   • Perform only medically necessary procedures.

   • Avoid unnecessary scans that do not affect patient care.

   • Follow established clinical guidelines for all patient groups.

2. Dose Optimization

   • Apply the ALARA (As Low As Reasonably Achievable) principle.

   • Adjust imaging settings based on patient size, age, and condition.

   • Use technologies such as automatic exposure control, iterative reconstruction, and low-dose protocols.

3. Equipment Safety and Quality Assurance

   • Regularly maintain and calibrate imaging equipment.

   • Conduct quality assurance checks to ensure accurate dose delivery.

   • Utilize modern systems with built-in dose-monitoring tools.

4. Patient Protection

   • Use shielding like lead aprons and thyroid collars when needed.

   • Limit imaging to the clinically required area.

   • Position patients carefully to reduce unnecessary exposure.

5. Staff Safety

   • Provide comprehensive radiation safety training.

   • Maintain safe distances and use protective barriers.

   • Monitor occupational exposure with dosimeters.

6. Pediatric Considerations

   • Implement child-specific imaging protocols.

   • Minimize repeat scans and explore alternative methods like MRI or ultrasound.

7. Dose Monitoring and Documentation

   • Record radiation doses for each procedure.

   • Track cumulative exposure for patients with repeated imaging.

   • Review data to identify opportunities for dose reduction.

8. Regulatory Compliance

   • Follow local and international radiation safety regulations.

   • Participate in audits and accreditation programs.

Emerging Strategies

• Use artificial intelligence to optimize imaging protocols.

• Employ real-time dose monitoring systems.

• Educate patients about radiation risks and safety practices.
