Model construction and validation of dual-energy CT multi-parameters combined with clinical indicators for predicting lymph node metastasis in pancreatic ductal adenocarcinoma
Lymph node metastasis (LNM) is a critical prognostic factor in pancreatic ductal adenocarcinoma (PDAC), but preoperative prediction remains challenging. This study aimed to evaluate the predictive value of combining dual-energy CT (DECT) multiparameters with clinical indicators for LNM in PDAC, and to develop a p...
