To evaluate the effectivity of a combined intervention of information and communication to reduce magnetic resonance imaging (MRI) anxiety using prolactin and cortisol as biochemical markers and State Trait Anxiety Inventory (STAI).
This study is a randomized prospective research. Sample size was 33 patients. Fourteen patients were enrolled as study group, compared to 19 patients as control group. Blood samples were collected by venous sampling, and STAI was filled before and after scan. State anxiety inventory was used twice. Study group received a standard information about MRI scans and were communicated with 2 minute intervals via intercom; control group had no intervention. Blood samples were carried in ice to be centrifuged and stored as soon as they were taken to study prolactin and cortisol. Data were stored and analyzed by SPSS 17.0. P value for significance was accepted as 0.05.
Prolactin-pre, prolactin-post, cortisol-pre, cortisol-post, cortisol percent increase, Trait Anxiety Inventory (TAI), SAI (State Anxiety Inventory) pre-scan and post-scan levels were similar between demographic groups. Cortisol-pre levels were similar between study and control, however prolactin-pre levels were significantly higher in control group. Study group had 6% lower cortisol level post-scan, whereas control group had 18% increase. Study and control groups had similar Trait Anxiety and SAI-pre scores. SAI-post scores were lower in study group when compared with control group. Study group also had lower SAI-post scores than SAI-pre, whereas control group had higher.
MRI anxiety can be reduced by information and communication. This combined method is shown to be effective and should be used during daily radiology routine.
以催乳素和皮质醇作为生化标志物，采用状态-特质焦虑量表（STAI），评估信息与沟通的联合干预对降低磁共振成像（MRI）焦虑的有效性。
本研究为随机前瞻性研究。样本量为33例患者。14例患者被纳入研究组，19例患者作为对照组。通过静脉采血采集血样，并在扫描前后填写STAI。状态焦虑量表使用两次。研究组接受关于MRI扫描的标准信息，并通过对讲机每隔2分钟进行沟通；对照组未进行干预。血样采集后置于冰上，离心后尽快储存以研究催乳素和皮质醇。数据使用SPSS 17.0进行存储和分析。显著性P值设定为0.05。
人口统计学组之间的催乳素扫描前、催乳素扫描后、皮质醇扫描前、皮质醇扫描后、皮质醇升高百分比、特质焦虑量表（TAI）、扫描前和扫描后的状态焦虑量表（SAI）水平相似。研究组和对照组的皮质醇扫描前水平相似，但对照组的催乳素扫描前水平显著更高。研究组扫描后皮质醇水平降低6%，而对照组升高18%。研究组和对照组的特质焦虑和SAI-扫描前得分相似。与对照组相比，研究组的SAI-扫描后得分更低。研究组的SAI-扫描后得分也低于SAI-扫描前，而对照组则更高。
信息与沟通可降低MRI焦虑。这种联合方法被证明是有效的，应在日常放射检查中使用。
