Abstract
•CT technologists showed good knowledge about the exposure parameters.•CT technologists were capable of modifying parameters.•CT technologists should be involved in protocols designing.•More efforts about DRLs importance and implementation should be made.
This study aimed to assess the knowledge and practice of computed tomography (CT) clinical practice preceptors in terms of CT parameters affecting patient dose and image quality.
A self-administered questionnaire that surveyed the participants’ demographic information and knowledge about CT parameters and radiation doses was distributed to 60 CT preceptors.
The response rate of the invited technologists was 92 %. 38 (69 %) males and 17 (31 %) females aged between 24 and 59 years, with a mean age of 37.8. The participants’ experience ranged between 2 and 24 years, with a mean of 15.5 years. The average knowledge score was 72.2 %, with a range of correct answers of 9–18 and a mean (±SD) of 13.1 ± 2.1. The participants showed a low awareness of diagnostic reference levels (DRLs). However, they demonstrated good overall knowledge, with a potential for improvement and confidence in practice.
Continuous medical education and professional development are a priority for improvement to ensure reliable delivery of health care and best practice. The findings of this study can be used by education institutes and health organizations when designing educational programs to ensure the highest training and performance of their technologists.
