We conducted color Doppler ultrasonographic examination (CDU) of 123 patients with pancreatic tumors to determine if CDU can be used in the differential diagnosis of these lesions. Results of pathologic diagnosis showed 92 of these tumors to be ductal carcinomas; 9, intraductal papillary adenomas or adenocarcinomas; 5, neuroendocrine tumors; 3, mucinous cystadenomas or cystadenocarcinomas; 3, serous cystadenomas; 3, solid cystic tumors; 2, adenosquamous carcinomas; 2, leiomyosarcomas; and 4, tumors forming chronic pancreatitis. Color images were detected in 5 (5%) of the 92 ductal carcinomas, 4 (80%) of the 5 neuroendocrine tumors, and all of the 2 adenosquamous carcinomas and 2 leiomyosarcomas. Wave forms by the fast Fourier transform (FFT) algorithm mode were pulsatile in 2 (40%) of the 5 ductal carcinomas with color images and pulsatile in 7 (78%) of the 9 non-ductal tumors with color images. The results suggest that examination of blood flow by CDU is useful for differentiating pancreatic tumors.
