Improving Radiographers’ Knowledge Through the Dissemination of Research Findings on Brain CT Examination Techniques for Emergency Patients to Overcome Motion Artifacts

 This community service activity aimed to improve radiographers’ knowledge and understanding of how to manage motion artifacts in computed tomography (CT) examinations and how to apply a fast-scan protocol to emergency patients. Motion artifacts are image distortions caused by patient movement during data acquisition, and they can reduce diagnostic image quality. They are a particular concern in emergency patients, especially those with head trauma, reduced consciousness, or difficulty maintaining position during the examination. The activity was designed as an educational intervention with a one-group pre-test–post-test evaluation. It consisted of a dissemination session on research findings concerning brain CT examination techniques, followed by an assessment of participants’ knowledge using a 15-item questionnaire covering the concept of motion artifacts, their causes, preventive measures, radiographer–patient communication, and the fast-scan protocol for head CT. Eleven radiographers at the Radiology Installation of RSI Siti Rahmah Padang took part. The mean proportion of correct answers was 37.6% in the pre-test and 100% in the post-test, a descriptive increase of 62.4 percentage points. These results indicate that the dissemination session had a positive effect on participants’ knowledge of motion artifact prevention and of the importance of applying a fast-scan protocol in emergency patients. The activity is expected to support radiographers’ competence in optimizing image quality, examination efficiency, and patient safety. Further evaluation through practice observation and image quality assessment is needed to determine whether this knowledge is applied in radiology services.
