To evaluate the prevalence of and risk factors for failure of fetal magnetic resonance imaging (MRI) due to maternal claustrophobia or malaise.
This retrospective cohort study included pregnant women who underwent fetal MRI for clinical indications or research purposes between January 2012 and December 2019 at a single center. One group included patients who completed the entire examination and the other group inlcuded patients who interrupted their MRI examination due to claustrophobia/malaise. We estimated the rate of MRI failure due to maternal claustrophobia/malaise and compared maternal and clinical variables between the two groups. Multiple logistic regression analysis was performed to identify independent risk factors for claustrophobia/malaise during MRI examination in pregnancy.
Among 3413 patients who agreed to undergo fetal MRI, the prevalence of failure because of claustrophobia or malaise was 2.1%. The rate of claustrophobia/malaise in patients who underwent MRI for a clinical indication was lower compared to that in patients who underwent MRI for research purposes only (0.6% (4/696) vs 2.4% (65/2678); P = 0.003). Fetal MRI performed for research purposes only (adjusted odds ratio (aOR), 0.05 (95% CI, 0.01-0.48); P = 0.003), higher maternal age (aOR, 1.07 (95% CI, 1.02-1.12); P = 0.003) and later gestational age at the time of fetal MRI (aOR, 1.46 (95% CI, 1.16-2.04); P = 0.008) were independent risk factors for claustrophobia/malaise. Shorter fetal MRI duration (aOR, 0.77 (95% CI, 0.63-0.88); P = 0.001) was also associated with claustrophobia/malaise during the procedure. Body mass index, ethnic origin, multiple pregnancy, being parous and size of the magnetic bore were not associated with MRI failure due to claustrophobia/malaise.
The rate of fetal MRI failure due to claustrophobia or malaise was found to be low, particularly when the examination was performed for a clinical indication, and should not be considered a common problem in the pregnant population. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.
评估因孕妇幽闭恐惧症或身体不适导致胎儿磁共振成像（MRI）检查失败的发生率及危险因素。
这项回顾性队列研究纳入了2012年1月至2019年12月在单一中心因临床指征或研究目的接受胎儿MRI检查的孕妇。一组包括完成全部检查的患者，另一组包括因幽闭恐惧症/身体不适而中断MRI检查的患者。我们估计了因孕妇幽闭恐惧症/身体不适导致的MRI检查失败率，并比较了两组之间的孕妇和临床变量。进行多因素逻辑回归分析以确定孕期MRI检查期间幽闭恐惧症/身体不适的独立危险因素。
在3413名同意接受胎儿MRI检查的患者中，因幽闭恐惧症或身体不适导致检查失败的发生率为2.1%。因临床指征接受MRI检查的患者中幽闭恐惧症/身体不适的发生率低于仅因研究目的接受MRI检查的患者（0.6%（4/696）对2.4%（65/2678）；P = 0.003）。仅为研究目的进行的胎儿MRI检查（调整后的优势比（aOR），0.05（95%置信区间，0.01 - 0.48）；P = 0.003）、孕妇年龄较大（aOR，1.07（95%置信区间，1.02 - 1.12）；P = 0.003）以及胎儿MRI检查时孕周较大（aOR，1.46（95%置信区间，1.16 - 2.04）；P = 0.008）是幽闭恐惧症/身体不适的独立危险因素。较短的胎儿MRI检查时长（aOR，0.77（95%置信区间，0.63 - 0.88）；P = 0.001）也与检查过程中的幽闭恐惧症/身体不适有关。体重指数、种族、多胎妊娠、经产情况和磁体孔径大小与因幽闭恐惧症/身体不适导致的MRI检查失败无关。
因幽闭恐惧症或身体不适导致胎儿MRI检查失败的发生率较低，尤其是当检查是出于临床指征时，不应将其视为孕妇群体中的常见问题。© 2022国际妇产科超声学会。
