Abstract
The placenta accrete is a kind of emergency and it leads to maternal postpartum hemorrhage, and one of the causes of death. Its aims is to evaluate diagnostic ability and findings of MRI in placental accrete of different types. This study included 27 pregnant women who were all histologically confirmed placental accrete after operation. According to the Maldjia diagnostic MRI criteria. The sensitivity and accuracy of MRI imaging were compared, and the MRI features of placental accrete were also described. The results showed a statistically significant difference among the three radiologists in MRI classification (P<0.05). For the type 0 and the type 3, there is a statistical difference between MRI diagnosis to the type 0 and the type 3 (P<0.05), and Kappa test also showed the difference (P<0.05). And for the type 1 and the type 2, especially for the type 1, there is a good consistency with the pathological results (P>0.05), chi square test (c2) showed no difference between the two types diagnostic capabilities (P>0.05). ADC and high b value DWI both showed slightly high signal of placental accrete. Residual placenta demonstrated "flower braid" or "mushroom" inhomogeneous enhancement. Comparison of MRI and US, 0 and 1 type are no obviously difference between US and MRI (P>0.05), but there are statistical difference (P<0.05) for distinguishing type 2 and type 3. MRI has a high diagnostic accuracy in placental implantation and the location, extent and depth of its invasion, displaying the condition of blood supply, and the drawing the typing diagnosis based on them. Moreover, MRI was more useful than US in distinguishing type 2 and type 3 of placental accrete.
