核磁共振对妊娠晚期子宫后壁前置胎盘的诊断价值

Diagnostic Value of Nuclear Magnetic Resonance in Placenta of Posterior Wall of Uterine in Late Pregnancy

目的:对妊娠晚期子宫后壁前置胎盘患者采用核磁共振进行诊断,分析其诊断价值。方法:选择70例后壁胎盘孕妇参与研究,对所有患者均采用超声检查和核磁共振检查,对比两种检查的准确率。结果:经过手术病例检查,70例后壁胎盘孕妇中共有27例子宫后壁前置胎盘患者,超声检查诊断的准确率为78.57%,核磁共振检查诊断的准确率为97.14%,差异具有统计学意义(P<0.05)。结论:虽然目前针对前置胎盘的检查中超声检查的应用较为广泛,但是仍存在漏诊和误诊情况,而核磁共振比超声检查具有更高的诊断准确率,值得临床推广应用。

Objective：To diagnose the placenta previa in the late trimester of pregnancy by MRI, and to analyze its diagnostic value. Methods：70 cases of pregnant women participated in the study on the wall of the placenta, all patients were treated with ultrasound and MRI, the accuracy comparison of two kinds of examination. Results： After surgery, 70 cases of posterior wall placenta in pregnant women, a total of 27 patients with posterior uterine wall placenta previa, by ultrasound examination, the diagnostic accuracy rate of 78.57%, after the magnetic resonance imaging, the diagnostic accuracy was 97.14%. There was significant difference between the two test methods（P〈0.05）.Conclusion： Although the application of hyper sonography in placenta previa is widely applied, there are still missed diagnosis and misdiagnosis. NMR is more accurate than ultrasonography in the diagnosis of placenta previa. Therefore, it is worthy of clinical application.
