Resectable pancreatic ductal adenocarcinoma: association between preoperative CT texture features and metastatic nodal involvement.

ABSTRACT: BACKGROUND:To explore the relationship between the lymph node status and preoperative computed tomography images texture features in pancreatic cancer. METHODS:A total of 155 operable pancreatic cancer patients (104 men, 51 women; mean age 63.8 ± 9.6 years), who had undergone contrast-enhanced computed tomography in the arterial and portal venous phases, were enrolled in this retrospective study. There were 73 patients with lymph node metastases and 82 patients without nodal involvement. Four different data sets, with thin (1.25 mm) and thick (5 mm) slices (at arterial phase and portal venous phase) were analysed. Texture analysis was performed by using MaZda software. A combination of feature selection algorithms was used to determine 30 texture features with the optimal discriminative pe
