Representative cases and delineation of ROI. (a, b) A 37-year-old woman at 32 gestation weeks with placenta previa. She had a history of G2P1 with one previous cesarean delivery. She had an EBL of 700 mL during cesarean delivery. Based on the clinical-radiomics model, the predicted radiomics score was 0.0508; she was classified as having a low risk of PPH. (c, d) A 33-year-old woman at 36 gestation weeks with placenta previa. She had a history of G1P1 with one previous cesarean delivery. She had an EBL of 6600 mL during cesarean delivery. Based on the clinical-radiomics model, the predicted R-score was 0.9130; she was classified as having a high risk of PPH
