Magnetic resonance imaging (MRI) is an important modality in diagnostics and treatment follow-up. However, MRI can be perceived as unpleasant even though the examination is non-invasive. Patients' knowledge of the MRI procedure is usually scarce, which may enhance patient anxiety at examination. We investigated the effects on anxiety and satisfaction with an information booklet on MRI compared to a placebo booklet delivered to adult patients prior to their first MRI examination.
This randomized, single-blind, placebo-controlled trial included 197 patients. The intervention group (n = 95) received a booklet about MRI prior to the examination, whereas the control group (n = 102) received a placebo booklet of the same size and layout but containing general information. The State Trait Anxiety Inventory with supplementary questions from the Quality from the Patient's Perspective questionnaire were used as patient-reported outcome measures.
Anxiety did not differ between the groups, either prior to MRI or during the examination, but those who received the placebo booklet were at higher risk of experiencing high anxiety prior to the MRI examination (odds ratio 2.64; P = 0.029). The intervention group was more satisfied with the information received (P = 0.044), and a majority of participants in both groups (≥87%) considered it important to obtain information on the MRI procedure.
Written MRI information decreases the risk of high anxiety levels before MRI and improves patient satisfaction with the information. Further research is needed to investigate whether written information prior to MRI is beneficial not only from the perspective of the patient but may also be cost-effective.
Written MRI information prior to the examination is recommended in radiography care.
磁共振成像（MRI）是诊断和治疗随访的重要手段。然而，尽管检查是非侵入性的，但 MRI 仍可能被认为是不愉快的。患者对 MRI 程序的了解通常很少，这可能会增加患者在检查时的焦虑。我们研究了在成人首次 MRI 检查前向患者提供 MRI 信息手册与安慰剂手册对焦虑和满意度的影响。
这是一项随机、单盲、安慰剂对照试验，纳入了 197 名患者。干预组（n=95）在检查前收到了一本关于 MRI 的手册，而对照组（n=102）收到了一本大小和布局相同但包含一般信息的安慰剂手册。使用状态特质焦虑量表和来自患者视角的质量问卷中的补充问题作为患者报告的结果测量。
无论是在 MRI 检查前还是检查期间，焦虑两组之间都没有差异，但那些接受安慰剂手册的人在 MRI 检查前出现高度焦虑的风险更高（优势比 2.64；P=0.029）。干预组对收到的信息更满意（P=0.044），而且两组的大多数参与者（≥87%）认为获得 MRI 程序的信息很重要。
书面 MRI 信息可降低 MRI 检查前出现高度焦虑的风险，并提高患者对信息的满意度。需要进一步研究以确定在 MRI 检查前提供书面信息不仅对患者有益，而且是否具有成本效益。
在放射科护理中，建议在检查前提供书面的 MRI 信息。
