对39例胰腺疾病患者的40个病变进行了超声造影（US）和超声内镜（EUS）检查，以评价其特征性表现。胰腺癌（导管细胞癌）呈阴性或轻度强化。胰岛细胞瘤、由微囊组成的浆液性囊腺瘤和导管内乳头状腺瘤强化明显。实性和乳头状肿瘤在病灶中央表现为强化。6例假肿瘤性胰腺炎中4例呈等强化，且等强化消失早于胰腺实质。2例呈轻度或阴性强化，类似胰管细胞癌。超声血管造影可用于评价各种胰腺病变的血管分布，特别是在动态实时图像中的小病变。EUS血管造影也可用于评价超声无法检测到的病变的血管分布。
Extracorporeal ultrasonographic (US) angiography and endoscopic ultrasonographic (EUS) angiography were performed in 40 lesions on 39 patients with various pancreatic diseases to evaluate characteristic findings. Pancreatic cancer (duct cell carcinoma) showed negative or slight enhancement. Islet cell tumor, serous cystadenoma composed of microcysts, and intraductal papillary adenoma showed strong enhancement. Solid and papillary tumor showed enhancement in the central lesion. Four of 6 cases with pseudotumorous pancreatitis had iso-enhancement which disappeared earlier than that in the pancreatic parenchyma. However, 2 cases showed slight or negative enhancement similar to pancreatic duct cell carcinoma. US angiography is useful in evaluating the vascularity of various pancreatic lesions, especially small lesions, in dynamic real-time images. EUS angiography is also useful in evaluating the vascularity in lesions that cannot be detected by US.
