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. 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.
对5例胰腺内分泌肿瘤患者进行了超声（US）、内镜超声（EUS）、彩色多普勒超声（color Doppler US）及彩色多普勒内镜超声（color Doppler EUS）检查。超声能够检测出5个肿瘤中的4个（80%），但无法充分评估内部回声。彩色多普勒超声仅在1例（25%）中显示出内部血流。内镜超声能够清晰检测出所有5例（100%），彩色多普勒内镜超声在所有病例中均能显示大量内部血流。彩色多普勒内镜超声在血管造影上表现为高血运表现，在组织学上表现为增生性血管表现。因此，超声尤其是内镜超声有助于诊断肿瘤位置及评估内部回声，而彩色多普勒内镜超声有助于评估肿瘤的血管情况。
