Methods and materials

21 patients with malignant pancreatic tumors underwent CA of the tumor. Duplex ultrasound, CT and MRI were performed before and after operation: on 1st day, after 3 months, 6 months.

Duplex ultrasound criteria of the completeness of CA in pancreatic tumors: blood flow changes in the tumor.

CT criteria of the completeness of CA in pancreatic tumors: tumor contrast enhancement changes (tumor density calculation by formula: [tumor density CE phase – tumor density native]/aorta blood density CE phase); also changes of tumor size, signs of vascular invasion and the severity of pancreatic hypertension were evaluated at 3 and 6 months after CA.

MRI criteria of the completeness of CA in pancreas tumors: apparent diffusion coefficient  increase in pancreatic tumor; also changes of tumor size, signs of vascular invasion and the severity of pancreatic hypertension were evaluated at 3 and 6 months after CA.
