基于视频的暴露疗法在降低MRI焦虑和改善结果方面的有效性：一项前瞻性实验研究

To assess the benefit of patients’ exposure to a preparatory video on anxiety, cooperation, and examination quality during Magnetic Resonance Imaging (MRI). Data were collected using questionnaires addressing patient experience and examination outcomes. Anxiety was measured using a 0–10 visual analog scale (VAS) before and after video exposure only in the experimental group. We recorded cooperation, movement, and repeat acquisitions during the MRI exam. Within the experimental group, mean VAS anxiety scores decreased significantly from 6.66 ± 3.39 before video exposure to 2.93 ± 3.61 afterward
