Resectability of Pancreatic Head Cancer by Contrast-enhanced MDCT:a Multi-center Study

Preoperative Evaluation of Resectability of Pancreatic Head Cancer by Contrast-enhanced MDCT:a Multi-center Study

The purpose of this multicenter and double-blind clinical trial is to prospectively assess the sensitivity, specificity, negative predictive value, positive predictive value, and accuracy in respectability of pancreatic head cancer with contrasted-enhanced MDCT and its various post processing techniques, taking operational and pathological records as the gold standard.

Inclusion Criteria:

• Patients with (or suspected) pancreatic head cancer
• Being examined by contrasted-enhanced MDCT
• Receiving surgical treatment (including palliative surgery) in all research centers

Exclusion Criteria:

• Patients having (or suspected) pregnancy or breast-feeding
• Patients having allergic reactions to iodinated contrast agents or Hypersensitivity reactions to allergens(including drugs)
• Patients receiving ERCP before contrasted-enhanced MDCT examination
• Patients without surgery because of a high degree of surgical risk
