Abstract

Objective To evaluate the clinical value of MRI in diagnosis of placenta previa and Placental Implantation Abnormality. Methods A total of 21 cases of placenta previa with and without placental implantation abnormality confirmed by operating pathology which were examined by conventional MRI scans. To retrospectively analyze the diagnostic accuracy of MRI of the 21 cases. Results Among these 21 patients, there were 20 cases of placenta previa diagnosed by MRI and1 case missed diagnosed. The diagnostic accurate rate of placenta previa by MRI was 95.2%. While there were14 cases of placental implantation abnormalityconfirmed by MRI and1 case missed diagnosed. The diagnostic accurate rate of placental implantation abnormality by MRI was 93.3%. Conclusion MRI has high value in the diagnosis of placenta previa and placental implantation abnormality.
