Purpose To establish and validate two predictive radiomics models for preoperative prediction of lymph node metastases (LNMs) and tumor deposits (TDs) respectively in rectal cancer (RC) patients. Methods A total of 139 RC patients (98 in the training cohort and 41 in the validation cohort) were enro...
