Ten Steps You Can Take to Optimize Image Quality and Lower CT Dose for Pediatric Patients

This article suggests 10 steps that radiologists and radiologic technologists, with the assistance of their medical physicist, can take to obtain good quality CT images while properly managing radiation dose for children undergoing CT.

Ten Steps to Lower CT Radiation Dose for Patients While Maintaining Image Quality

1. Increase Awareness and Understanding of CT Radiation Dose Issues Among Radiologic Technologists
1. 診療放射線技師がX線CTの線量の問題への関心を高め理解を深めるようにする。

2. Enlist the Services of a Qualified Medical Physicist
2. 適切な医学物理士の支援を得る。

3. Obtain Accreditation From the American College of Radiology for Your CT Program
3. ACRからCT撮像検査の認証を得る。

4. When Appropriate, Use an Alternative Imaging Strategy That Does Not Use Ionizing Radiation
4. 可能であれば電離放射線を用いない別の画像検査法を用いる。

5. Determine if the Ordered CT Is Justified by the Clinical Indication
5. オーダーのあったCT検査が、臨床上、正当なものかどうかを判断する。

6. Establish Baseline Radiation Dose for Adult-Sized Patients
6. 成人サイズの患者での基礎となる線量を決めておく。

7. Establish Radiation Doses for Pediatric Patients by “Child-Sizing” CT Scanning Parameters
7. 小児サイズのCT撮像パラメータを用いることで、小児患者での線量を決めておく。

8. Optimize Pediatric Examination Parameters
8. 小児での撮像パラーメータを最適化しておく。

9. Scan Only the Indicated Area: Scan Once
9. 必要な範囲のみ照射する:再撮像しない

10. Prepare a Child-Friendly and Expeditious CT Environment
10. 子供が快適に過ごせて迅速に検査できるように検査室を整える。
