A Study of Knowledge and Attitude of Medical Staff Towards 3D Black Blood MR Angio Methods in High-Resolution Magnetic Resonance Vessel Wall Imaging of Intracranial Arteries

Year: 2025

Type: article

Abstract: Objective: This study aims to investigate the knowledge and attitude of medical staff towards 3D Black Blood MR Angio methods in high-resolution magnetic resonance vessel wall imaging (HR-MRI) of intracranial arteries. Methods: A cross-sectional study conducted from August 2-25 2024 collected demographic information, knowledge, and attitude scores of medical staff through self-designed questionnaires. The questionnaires exhibited a high internal consistency (Cronbach's α = 0.870). The Questionnaire Star online platform was used, and a WeChat-based applet generated a QR code for participants to access and complete the questionnaire. Results: A total of 287 valid questionnaires were enrolled. The median (25% quartile and 75% quartile) of knowledge and attitude scores were 12 (9, 15) (possible range: 0-17) and 59 (55, 64) (possible range: 18-90). The correlation analysis demonstrated a positive correlation between knowledge and attitude (r = 0.361, P < 0.001). Multivariate logistic regression analysis showed that holding an intermediate title (OR = 4.065, 95% CI: 1.529, 10.808, P = 0.005), a vice senior title (OR = 5.443, 95% CI: 1.614, 18.361, P = 0.006), and having no prior experience with HR-MRI (OR = 0.422, 95% CI: 0.236, 0.753, P = 0.003) were independently associated with knowledge. Having one year or less of work experience (OR = 0.095, 95% CI: 0.010, 0.952, P = 0.045), having 1-3 years of work experience (OR = 0.330, 95% CI: 0.114,0.957, P = 0.041), and having no prior experience with HR-MRI (OR = 0.422, 95% CI: 0.236,0.753, P < 0.001) were independently associated with attitude. Conclusion: This study identified suboptimal knowledge and inconsistent attitudes toward intracranial HR-MRI among medical staff, with professional title, scanning experience, and prior HR-MRI exposure being key determinants. Addressing these gaps through competency-based credentialing and standardized protocol dissemination is critical to realizing HR-MRI's clinical potential in cerebrovascular care.
