摘要
目的评价快速反转恢复运动抑制序列(FIRM)在胎儿先天性膈疝诊断中的应用。方法选择30例20～39周孕龄的孕妇,产前常规超声(US)检查怀疑胎儿先天性膈疝后在2～3天内行MRI检查,在行快速平衡稳态采集(FIESTA)和单次激发快速自旋回波(SSFSE)序列外均再行FIRM序列的扫描,将其诊断结果与超声及(引)产后结果进行比较。结果 30例均为单胎,膈疝位于左侧24例,膈疝位于右侧6例,随访结果与产前MRI诊断一致。结论 FIRM序列作为FIESTA和SSFSE序列的补充序列,在诊断胎儿先天性膈疝方面有重要作用。
Objective To evaluate the application of fast inversion recovery motion insensitive （FIRM） sequence on the diagnosis of fetal congenital diaphragmatic hernia. Methods Thirty pregnant women with 20 to 39 weeks gestational age were studied with a 1.5T superconductive MR unit within 2 to 3 days after ultrasound studies. The imaging protocol included fast-imaging employing steady-state acquisition （FIESTA）, single-shot fast spin echo （SSFSE） and fast inversion recovery motion insensitive （FIRM） sequences. Prenatal US and MR imaging findings were compared with postnatal diagnoses or autopsy. Results 30 cases of pregnant women were all turned out with single fetuses. Among them, 24 fetuses were with a left-sided and 6 with right-sided diaphragmatic hernia. For all cases, the diagnoses established by MR imaging were correct when compared with follow-up results. Conclusions FIRM sequence as a complement sequence of the FIESTA and SSFSE sequences, has an important role in the diagnosis of fetal congenital diaphragmatic hernia.
