[Abstract] Objective: To investigate the prenatal MRI imaging features of placenta previa complicated with placenta accreta.Materials and Methods: The clinical and MRI data of 48 cases of placenta previa including 12 placenta accreta confirmed by clinic and surgery were retrospectively analyzed.Results: Forty-three cases of placenta previa were diagnosed by MRI pre-operation, including 31 cases of complete placenta previa, 9 cases of partial placenta previa and 3 cases of marginal placenta previa. The overall diagnose accordance rate was 89.5% (43/48). Nine cases of placenta accreta were diagnosed by MRI pre-operation, the diagnose accordance rate was 75.0% (9/12).Conclusions: MRI has a high accuracy for the diagnosis of placenta previa, the combination of different MR sequence can make accurate diagnosis possible.
