The application value of prenatal color Doppler ultrasound and MRI in the diagnosis of implanted pernicious placenta previa
产前彩超与MRI诊断植入型凶险性前置胎盘的应用价值

摘要

目的 探讨产前彩色多普勒超声与磁共振成像（MRI）在诊断植入型凶险性前置胎盘方面的价值。方法 选取2024年1月至2025年1月期间我院收治的80例植入型凶险性前置胎盘患者，以诊断方式的不同为依据进行分组，对照组采用产前彩超诊断，观察组采用MRI诊断，比较两组诊断效能。结果 两组灵敏度、特异度、漏诊率、误诊率、诊断符合率差异并不显著（P＞0.05）。结论 在凶险型前置胎盘的产前诊断中，彩超与MRI均展现出显著的诊断效能，二者不仅经济实惠、安全可靠，还具备无创性、操作简便以及可重复检查等诸多优势。对于有进一步明确胎盘植入状况需求的患者，可酌情安排其接受MRI的深入检查。

Abstract

Objective To explore the value of prenatal color Doppler ultrasound and magnetic resonance imaging (MRI) in the diagnosis of invasive placenta previa.
Methods Eighty patients with invasive placenta previa who were admitted to our hospital between January 2024 and January 2025 were selected and divided into two groups based on different diagnostic methods. The control group was diagnosed with prenatal ultrasound, while the observation group was diagnosed with MRI. The diagnostic efficacy of the two groups was compared.
Results There was no significant difference in sensitivity, specificity, missed diagnosis rate, misdiagnosis rate, and diagnostic accuracy between the two groups (P>0.05).
Conclusion   In the prenatal diagnosis of dangerous placenta previa, both color ultrasound and MRI have shown significant diagnostic efficacy. They are not only economical, safe and reliable, but also have many advantages such as non invasiveness, easy operation, and repeatable examination. For patients who require further clarification of their placental implantation status, they may be arranged to undergo in-depth MRI examination at their discretion.
