Journal Title: INTERNATIONAL JOURNAL OF CURRENT RESEARCH - Year 2018, Vol 10, Issue 2
Abstract
Objective: To evaluate a CT head radiation dose reduction protocol in children using anatomical delineation, diagnostic confidence and imaging quality of CT brain as parameters. Method: The study prospectively reviewed head CT studies of 100 children, 50 with normal protocol and 50 with reduced radiation protocol. Image quality was assessed using five point grading scale based on anatomical delineation, diagnostic confidence and overall image quality. Results: The relative dose reduction between normal and reduced radiation protocol was approximately 15%. There was no statistically significant difference (p>0.05) in overall image quality by both observers. Conclusion: Pediatric CT dose can be reduced by approximately 15% while still maintaining anatomical delineation, diagnostic confidence and overall image quality.
