关于孕早期暴露于诊断性磁共振成像（MRI）的安全性的信息仍然很少。我们报告了一个连续的15名孕妇的病例系列，这些孕妇在怀孕的前三个月（暴露时的平均胎龄：3.8周）使用1.5特斯拉扫描仪对头部（n = 5）、颈椎（n = 4）、腰椎（n = 4）、骨盆（n = 1）或膝关节（n = 1）进行MRI扫描。对患者进行前瞻性随访，直至妊娠结束。2例病例接受钆作为造影剂。有15个婴儿活了下来。其中一名婴儿出生时左肾无法通过超声波检查可视化，另一名婴儿右脚脚趾重叠。作者认为这些异常均与MRI暴露无关。总之，我们的研究为已发表的关于MRI在妊娠早期妇女中的安全性的初步证据提供了支持。
Information on the safety of first-trimester exposure to diagnostic magnetic resonance imaging (MRI) remains scarce. We are reporting a case series of 15 consecutive pregnant women who underwent an MRI scan with a 1.5-Tesla scanner of either the head (n = 5), cervical spine (n = 4), lumbar spine (n = 4), pelvis (n = 1) or knee (n = 1) in their first trimester of pregnancy (mean gestational age at exposure: 3.8 weeks). Patients were prospectively followed up until the completion of their pregnancy. Two cases received gadolinium as a contrast agent. There were 15 babies born alive. Of them, one baby was born with the left kidney not visualised by ultrasound examination, and another one with an overlapping toe in the right foot. None of these abnormalities were considered by the authors related to the MRI exposure. In conclusion, our study provides support to published preliminary evidence regarding the safety of MRI in the first-trimester pregnant women.
