Computed Tomography (CT) dose is on ECRI Institute’s 2010 list of top 10 technology hazards. Recommendations for regulating CT radiation dose is thus, expanded by the Institute.
High CT radiation doses are being delivered to patients on a daily basis, putting them at an increased risk of developing cancer. Hence, keeping CT radiation dose in check is a high priority safety concern for hospitals. While increased levels of radiations may put patients at risk, diminishing the same, will affect the image quality that may result in incomplete examination or rescanning of the image. The process will expose the patients to even more radiation.
Practical esteem to balance between the degree of radiation are presented in a new guidance article, “CT Radiation Dose: Understanding and Controlling the Risks,” released by ECRI Institute, an independent, nonprofit organization that researches the best modes of care. This comprehensive Health Devices article expands on the recommendations about controlling CT radiation dose published in ECRI Institute’s 2010 Top 10 Technology Hazards list.
ECRI Institute emphasizes that the responsibility also lies with the facility itself, referring physicians, medical physicists, radiation technologists, and CT device manufacturers. The article includes sixteen practical recommendations that every facility should identify with, to help control radiation dose in CT.
The recommendations are set in 5 major sections:
- protocol optimization,
- prioritizing dose reduction,
- patient selection,
- the technician’s responsibilities,
- quality assurance.
Dr.Keller, vice president, health technology evaluation and safety, ECRI Institute, considers the latest CT models are created with dose-saving technologies, but they may not be very affordable for many organizations. “In time, these technologies will become more widely installed,” says Keller. “Until then, there are a number of effective strategies every facility can implement to reduce dosage.The article also includes a dedicated section on dose-reduction technologies and the amount of dose savings they each achieve.
