Abstract:
Objective To evaluate the value of dual-phase spiral CT scanning in diagnosis of small pancreatic carcinoma.Methods 21 cases with small pancreatic carcinoma (≤2 cm) underwent plain CT scan and dual-phase eahanced spiral CT including arterial phase(20~25 s after infusion)and pancreatic phase(50~60 s after infusion)with a 100 ml bolus injection of contrast material at 3~6 ml/s.CTattenuation values of tumor and normal pancreas in all scanning phase were obtained.Results The mean CT value of tumor was(42?14) HU(arterial phase)and (48?18) HU(pancreatic phase),the mean CT value of normal pancreas was (105?15) HU(arterial phase)and (86?11) HU(pancreatic phase).The dens difference of tumor-pancreas was significantly on arterial phase (69?15) HU.Conclusion The maximum dens difference of tumor-pancreas can be obtained on arterial phase CT scan,it has advantages in diagnosing pancreatic carcinoma of early period and to judge the resectionability of pancreatic carcinoma.
