胰头肿块型胰腺炎与胰头癌的彩超分析与鉴别

目的分析和探讨胰头肿块型胰腺炎与胰头癌的声像图特征及鉴别要点,以提高超声诊断的准确率。方法回顾分析52例胰头疾病的图像特征,其中经手术和病理证实胰头癌41例和胰头肿块型胰腺炎11例,从病灶内有无胰管贯通、有无钙化斑块、后方有无回声衰减、胆总管下段扩张后狭窄的类型及胰周血管浸润、包埋等方面观察和分析其差异性。结果41例胰头癌声像图特征:肿块越小边界越清,胰管截断伴肿块后方回声衰减、远端胰管平直扩张、胆总管扩张后突然截断、胰周血管浸润和远处转移;11例胰头肿块型胰腺炎声像图特征:肿块内胰管穿通、有强回声斑块伴后方回声增强、远端胰管不规则扩张及胆总管扩张后呈鼠尾状狭窄。两组比较差异有显著性(P<0.05)。结论胰头肿块型胰腺炎及胰头癌具有较可靠的声像图特征,彩超对二者的鉴别诊断有一定的价值。

CDFI Analysis and Differentiation of Mass-type Chronic Pancreatitis and Pancreatic Carcinoma

Objective To analyse and summarize the sonographic characteristics of mass-type chronic pancreatitis and pancreatic carcinoma,and to emphasize the diagnostic accuracy.Methods A total of 52 cases with proved histologic diagnosiswere enrolled in our study.Color Doppler ultrasound were performed to define the presence of mass-type chronic pancreatitis and pancreatic carcinoma to detect whether there were ductus pancreaticus penetrating,calcification,weakened echoes and whether there was sudden interrupt ibn af...
