Inclusion criteria
Inclusion criteria: 1. Patients scheduled for radical resection: Clinically or radiologically diagnosed with pancreatic tumors (including PDAC, PNEN, IPMN, etc.); no distant metastasis; scheduled for radical resection of the pancreatic tumor. 2. Patients scheduled for non-surgical treatment: Pathologically confirmed pancreatic tumor; no other coexisting malignant solid tumors; scheduled to receive a pancreatic tumor treatment regimen.
Exclusion criteria
Exclusion criteria: 1. Patients scheduled for radical resection: CT images of poor quality or with artifacts that preclude complete post-processing analysis; an interval exceeding 1 month between the preoperative CT examination and the surgery; postoperative pathological results confirming a diagnosis other than pancreatic tumor. 2. Patients scheduled for non-surgical treatment: CT images of poor quality or with artifacts that preclude complete post-processing analysis; an interval exceeding 1 month between the pre-treatment CT examination and the initiation of treatment.
