Multi-slice CT: Examination And Assessment Of Resectability On Pancreatic Carcinoma

Objective: To investigate examination and evaluation method of pancreatic carcinoma with MSCT. Methods: The scanner was TOSHIBA Aquilion 16-slice CT. With dynamic cine mode, the optimal scanning time was determined. Then patients with pancreatic carcinoma were scanned with enhanced scanning in definite scanner time. The major peripancreatic vessels were displayed with CT angiography. The course of disease was staged reasonably, and resectability of pancreatic carcinoma was assessed in comparison of surgical results. Results: The optimal scanning time of arterial phase, pancreatic phase, and portal phase of pancreatic carcinoma were 28s, 42s and 55s. In display with CT angiography, the major peripancreatic vessel were inconvenient of encroachment by the tumor near head of pancreas, but were easy to be invaded by the tumor in body and tail of pancreas. CT could stage reasonably the course of disease, and could predict resectability of pancreatic carcinoma, with no statistical difference from the surgery. Conclusions: Use of MSCT enhancement scanning improves ideal imageology examination method in diagnosis of pancreatic carcinoma. CTA image is direct-viewing and accurate in judgement of major peripancreatic vessel invaded by pancreatic carcinoma. The prediction of resectability of pancreatic carcinoma with contrast enhancement CT has prospective significance in surgery.
