Patient Shielding in CHI
From May 2022, patients undergoing X-ray, fluoroscopy or CT examinations in CHI will no longer have shields placed on them during the exposure.
Keys Points to remember
- Technology advances in the 70 years since shielding was first introduced has led to a significant reduction in patient doses.
- All CHI imaging equipment have been optimised for use with children to ensure the lowest amount of x-ray radiation is used to acquire a diagnostic image.
- The amount of radiation which falls on areas outside the main field of view is negligible.
- Over 50 years of research have shown that radiation levels used in modern X-ray exams have no fertility or hereditary effects.
- Shields can potentially cover important anatomy which would cause repeat imaging.
- Should the patient move during the exam, the shield may also move and block the view of the area being imaged. This would also lead to repeat imaging.
- Shields can cause discomfort and are a potential infection control risk.
