ow radiation dose screening CT colonography: evaluation the efficacy of AIDR 3D

Not Applicable

• Conditions: Healthy individual

• Registration Number: JPRN-UMIN000009278
• Lead Sponsor: Kameda Medical Center

Brief Summary

ow-dose CTC reduces radiation dose >=48.5 % compared to routine-dose CTC. Iterative reconstruction improves overall CTC image quality compared with FBP. Iterative reconstruction reduces overall CTC image noise compared with FBP. Automated exposure control with iterative reconstruction is useful for low-dose CTC.
