The MRI-based radiomics nomogram for predicting massive hemorrhage during dilatation and curettage

Motivation: Dilation and Curettage (D&C) is the preferred treatment for Cesarean scar pregnancy (CSP) patients. However, current methods for preoperative assessment of intraoperative bleeding are limited. Goal(s): To develop a nomogram using radiomics and MRI-based clinical information to predict massive hemorrhage during D&C in CSP patients. Approach: 116 CSP patients were enrolled. Radiomics features and clinical variables were analyzed to conduct the radiomics and the clinical models. The nomogram was established by combining Radscore and the selected clinical variables. Results: Among the three models, the nomogram achieved the highest prediction performance with an AUC of 0.926 for test data. Impact: This study first developed the MR-based radiomics nomogram to accurately predict massive hemorrhage preoperatively in CSP patients.
