US, EUS, color Doppler US, and color Doppler EUS were performed for five cases of pancreatic endocrine tumors. US was able to detect four cases of five tumors (80%), but could not sufficiently evaluate the internal echo. Color Doppler US was able to reveal the blood flows inside in only one case (25%). EUS was able to detect clearly all five cases (100%), and color Doppler EUS was able to reveal a significant amount of the internal blood flow in all cases. Color Doppler EUS was reflected in hypervascular findings on angiogram and proliferating vascular findings on histology.<BR>Therefore, ultrasound, especially EUS was useful for diagnosing the location of the tumor and for evaluating the internal echo, whereas color Doppler EUS was useful for evaluating the vascularity of the tumors.
