【摘要】：目的探討MRI在產(chǎn)前診斷前置血管(VP)的臨床價(jià)值。方法回顧性分析20例VP的產(chǎn)前MRI表現(xiàn)。結(jié)果產(chǎn)前MRI診斷VP的準(zhǔn)確率為100%。中央性前置胎盤、邊緣性前置胎盤、球拍狀胎盤、帆狀胎盤并發(fā)VP概率最高,分別為1.1%、1.1%、1.47%、1.47%,臍帶匯入位置異常并發(fā)VP概率高于胎盤位置異常(0.22%、0.13%)。VP在不同切面上,T_2WI FSE及SSFSE序列均表現(xiàn)為管狀或類圓形斷面流空信號(hào)。20例中8例在胎盤邊緣走行,14例軸位走行方向自后向前,16例冠狀面和矢狀面圖像走行方向自下斜向上。結(jié)論 MRI多方位成像可以清晰顯示VP,有較高的診斷價(jià)值。
[Abstract]:Objective to investigate the clinical value of MRI in prenatal diagnosis of VPs. Methods Antepartum MRI findings of 20 cases of VP were retrospectively analyzed. Results the accuracy of prenatal MRI in the diagnosis of VP was 100%. Central placenta previa, marginal placenta previa, racket placenta and sail placenta were most likely to be associated with VP. The probability of abnormal umbilical cord entrainment with VP was higher than that of placental abnormal position 0.220.13. VP showed tubular or circular cross-section flow emptiness signal on different sections. 8 out of 20 cases performed axial position along the edge of placenta, both on T _ 2WI and SSFSE sequences, which were tubular or circular cross-sectional emptiness signal. The incidence of abnormal umbilical cord entrances was higher than that of placental abnormal position 0.22 / 0.13. VP showed tubular or circular cross-section flow emptying signal on different sections of the placenta in 8 out of 20 cases. There were 16 cases of coronal and sagittal images in the direction of walking from backward to forward. Conclusion MRI multi-directional imaging can clearly display MRI and has high diagnostic value.
