New Clinical-Radiomics Model Predicts Postpartum Diastasis Recti Abdominis Risk Early in Pregnancy
A new clinical-radiomics model has been developed to predict the risk of Diastasis Recti Abdominis (DRA) at 42 days postpartum, utilizing early-pregnancy two-dimensional grayscale ultrasound images. DRA is a common abdominal wall dysfunction characterized by the widening of the inter-rectus distance and stretching of the linea alba. The study, which included 428 pregnant women, extracted radiomic features from ultrasound images of the rectus abdominis and linea alba to create Radscore1 and Radscore2. These scores were then combined with early-pregnancy Body Mass Index (BMI) and exercise habits to form a comprehensive predictive model. The model demonstrated strong predictive capabilities, achieving AUCs of 0.892 in the training cohort and 0.859 in the testing cohort. Regular exercise was identified as a protective factor, while higher early-pregnancy BMI and specific radiomic scores were associated with an increased risk of DRA. This research aims to enable earlier identification of women at high risk for ...
