Assessment of Basic MRI Physics and Safety Knowledge Among Radiography Students, Interns, Technicians, and Technologists: A Questionnaire-Based Study
Abstract
Background: Magnetic Resonance Imaging (MRI) is a widely adopted diagnostic modality that operates without ionising radiation. However, strong static magnetic fields, pulsed radiofrequency (RF) energy, and rapidly switched gradient fields create a uniquely hazardous clinical setting. Consequently, robust knowledge of MRI physics and safety protocols is indispensable for all personnel who participate in MRI practice, ranging from undergraduate students to qualified technologists. Aim: To evaluate the current level of understanding of fundamental MRI physics and safety concepts among radiography students, interns, technicians, and technologists. Methodology: A questionnaire-based cross-sectional design was employed. Data were collected from 66 purposively selected participants via a validated 20-item structured questionnaire distributed through Google Forms. The tool comprised two domains: MRI Physics (14 items) and MRI Safety (6 items). Descriptive statistics (frequency, percentage, mean ± SD) summarised the data; Chi-square / likelihood-ratio tests examined associations between demographic variables and knowledge level (significance threshold: p < 0.05; SPSS v29.0). Results: Overall, 56.1 % of participants demonstrated an average level of knowledge (score 7–13/20) and 43.9 % achieved a good level (score 14–20/20); none were classified as poor. The mean overall score was 13.30 ± 2.81 (range 8–18). Educational qualification was the only demographic variable that showed a…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 66 participants or records.
