[Abstract] Objective To investigate the clinical value of MRI-based scoring system in predicting placenta accreta spectrum disorders.Materials and Methods: The data of 102 pregnant women suspected of placenta accreta spectrum disorders in our hospital were analyzed retrospectively. Nine items including MRI signs and clinical risk factors were selected to develop the MRI-based scoring system in predicting placenta accreta spectrum. Calculate average total score of each type of placenta implantation. The variance analysis and least-significant difference were used for comparison among groups and the ROC curve was drawn to calculate the cut-off score of each type of placenta implantation.Results Among 102 pregnant women, there were 35 cases of non-implantation type, score was (2.94±1.28), 28 cases of placenta accreta type, score was (5.54±1.75), 32 cases of placenta increta type, score was (9.88±2.37), and 7 cases of placenta percreta type, score was (13.57±1.90). There was statistically significant difference in scores among all groups (F=115.688, P<0.05). The ROC curve showed that the cut-off score between non-implantation and placenta accreta, between placenta accreta and placenta increta, and between placenta increta and placenta percreta were 3.5, 7.5, and 10.5, respectively.Conclusions MRI-based scoring system has a good value in predicting placenta accreta spectum disorders and depth of placenta imlantation.
