Abstract:
Objective To discuss the value of MRI in diagnosis of complications related to pregnancy.Methods MRI were per-formed in 22 cases of late pregnancy,7 cases of postpartum with vagina bleeding,and 1 case with eight weeks of gestation following irregular vagina bleeding,respectively.The position of placenta and umbilical cord were observed in the cases of late pregnancy.The shape and signal features of embryo were evaluated in the case of eight weeks gestation following irregular vagina bleeding.Residual placenta and its relationship with the wall of uterus were analyzed in the cases of postpartum with vagina bleeding.Results Among the 22 cases of late pregnancy,normal position of placenta were in 4 cases,placenta previa were in 18 cases,umbilical cord winding around fetal neck in 8 cases.9 cases of placenta previa complicated with placenta accreta were comfirmed by cesarean delivery,how-ever,only 6 cases of placenta accreta were detected on MRI.The residual placenta with placenta accreta was found in all 7 cases of postpartum patients.Hydatidiform mole was proved by pathology in the case of eight weeks gestation following irregular vagina bleeding,and it was showed as a mass with hypointensity on T1 WI and hyperintensity on T2 WI in uterine cavity.Conclusion The complications related to pregnancy such as placenta previa,umbilical cord winding around fetal neck,residual placenta,placenta ac-creta could be correctly displayed on MRI.Hydatidiform mole also could be diagnosed by combining the clinical symptoms with MR images.
