MRI快速成像技术在前置胎盘诊断中的应用价值
Application Value of the Fast Magnetic Resonance Imaging Technique in the Diagnosis of Placenta Previa
摘要
Abstract
Objective To evaluate the application value of the fast magnetic resonance imaging technique in the diagnosis of placenta previa.Methods 25 patients diagnosed with placenta previa underwent the single shot fast spin echo (SSFSE) sequence and fast imaging employing steady state acquisition (FIESTA) sequence scanning. The MRI features and clinic appearances of these 25 cases were analyzed.Results One out of the 25 cases was marginal placenta previa, 6 cases were partial placenta previa, 18 cases were complete placenta previa. Nine cases were placenta previa complicated with placenta accrete: 3 out of the 9 cases were placenta adhesion, 5 of 9 were placenta increta, 1 of 9 was placenta penetration. MRI could show the relationship between the placenta and the internal cervical oriifces straightly. The linear low signal intensity of the myometrium was discontinued in the cases complicated with placenta accrete, relatively high signal of the placenta intruded into the myometrium from the discontinued place.Conclusion The fast MRI technique has high clinical application value in the diagnosis of the placenta previa and placenta accrete.关键词
