Overview
Low dose CT protocols aim to reduce patient exposure without compromising diagnostic utility. Advances in reconstruction and detector technology enable dose reduction. Protocol customization is essential for different clinical indications.
Techniques
Iterative reconstruction and automated exposure control are key dose reduction tools. Tube current modulation and kV selection further optimize dose. Protocols must be validated for diagnostic performance.
Pediatric Considerations
Children require tailored low dose protocols and careful justification. Size based protocols and shielding reduce unnecessary exposure. Communication with caregivers supports informed imaging decisions.
Quality Monitoring
Dose tracking and audit ensure protocols remain effective and safe. Benchmarking against standards guides continuous improvement. Education of technologists and radiologists supports consistent practice.
