摘要

目的:探讨核磁共振成像(MRI)快速成像技术对凶险型前置胎盘(PP)的诊断价值分析。方法:选取2015年1月至2018年1月凶险型PP患者55例,给予二维快速稳态进动(2D-FIESTA)/单次激发快速自旋回波(SSFSE)序列MRI快速成像技术检查。结果:2D-FIESTA序列胎盘信号不均匀、胎盘内条状低信号影显示率明显低于SSFSE序列,2D-FIESTA序列子宫结合带中断、胎盘与周围结构区分显示率明显高于SSFSE序列,差异有统计学意义(P<0.05);在诊断粘连性、植入性PP符合率中,二者联合时分别为96.15%、95.65%,二者联合时明显高于2D-FIESTA序列,2D-FIESTA序列明显高于SSFSE序列,差异有统计学意义(P<0.05),三种方法诊断穿透性PP符合率均为100.00%,差异无统计学意义(P>0.05)。结论:MRI快速成像技术中,SSFSE、2D-FIESTA序列均对凶险型PP胎盘植入具有良好的诊断价值,二者联合时可提高诊断价值。
        Objective: To discuss the diagnostic value analysis of magnetic resonance imaging(MRI) rapid imaging technique for the aggressive placenta preplacenta(PP). Methods: 55 patients with aggressive PP were selected from January 2015 to January 2018, they were given 2-d rapid steady-state precession(2D-FIESTA), single-induced quick-spin echo(SSFSE) sequence MRI rapid imaging technique detection. Results: The placenta signal uneven, placenta low signal display rate of 2D-FIESTA sequence were significantly lower than those of the SSFSE sequence, the uterine junction interrupted, distinguish of placenta and surrounding structure display rate of 2D-FIESTA sequence were significantly higher than those of the SSFSE sequence, the difference was statistically significant(P<0.05). In the diagnosis of adhesion, implant PP compliance, the combination of two were significantly higher than those of the 2D-FIESTA sequence, the 2D-FIESTA sequence were significantly higher than those of the SSFSE sequence, the difference was statistically significant(P<0.05), the diagnosis of penetrative PP compliance of the three methods were 100.00%, the difference was no statistically significant(P>0.05). Conclusion: In MRI rapid imaging technique, the SSFSE, 2D-FIESTA sequence have good diagnostic value for the implantation placenta of aggressive PP, the combination of two can improve the diagnostic value.
