彩超与磁共振成像在胎盘植入诊断中的应用效能比较OA
Comparison of the Application Value of Color Doppler Ultrasound Imaging and Magnetic Resonance Imaging in the Diagnosis of Placenta Accreta
目的:分析磁共振成像(MRI)在不同部位及类型胎盘植入的检出和诊断价值,并与彩色多普勒超声(CDI)进行比较.方法:回顾性分析了2017年1月至2024年1月在宁德师范学院附属宁德市医院分娩的152例胎盘植入疑似病例,所有孕妇均在分娩前行CDI及MRI检查,以手术或组织病理结果为金标准.结果:101例(66.45%)孕妇经手术或组织病理证实为胎盘植入.MRI对胎盘植入的诊断灵敏度(97.03%)和准确率(96.05%)均高于CDI(分别为84.16%和88.16%),特别是在后壁胎盘植入的诊断中,MRI表现出更高的灵敏度和准确率(P<0.05).结论:MRI在胎盘植入诊断中具有较高的灵敏度和准确率,特别是在后壁胎盘植入的诊断中优于CDI,为临床提供了更可靠的诊断手段.
Objective:To investigate the application value of magnetic resonance imaging(MRI)in the diagnosis of placenta accreta and to compare it with color Doppler ultrasound imaging(CDI)Methods:A retrospective analysis was conducted on 152 suspected cases of placenta accreta admitted to Ningde Municipal Hospital Affiliated to Ningde Normal University from January 2017 to January 2024.All pregnant women underwent CDI and MRI examinations before delivery,with surgical or tissue pathological results serving as the gold standard.Results:Among the 152 pregnant women,101 cases(66.45%)were confirmed to have placenta accreta by surgery or tissue pathology.MRI demonstrated higher diagnostic sensitivity(97.03%)and accuracy(96.05%)for placenta accreta than CDI(84.16%and 88.16%,respectively).Particularly in the diagnosis of posterior wall placenta accreta,MRI exhibited higher sensitivity and accuracy(P<0.05).Conclusion:MRI has high sensitivity and accuracy in the diagnosis of placenta accreta,and is especially superior to CDI in the diagnosis of posterior wall placenta accreta,providing a more reliable diagnostic means for clinical practice.
