摘　　要：目的探讨各种超声造影表现在胰腺实质性病变(SLP)诊断中的价值。方法回顾分析54例已确诊病例的各种超声造影表现,探讨其诊断价值。结果不同病例的实质始增时间、病灶始增时间和增强峰值时间比较差异无显著性(P>0.05),而病灶达峰时间有较大差异(P<0.05)。以增强速度快慢诊断胰腺癌和肿瘤性胰腺炎的敏感性、特异性、准确性分别为:92.3%、73.3%、87.0%和77.8%、97.8%、94.4%;以增强模式诊断胰腺癌和肿瘤性胰腺炎的敏感性、特异性、准确性分别为:92.3%、86.7%、90.7%和77.8%、100%、96.3%。增强模式的诊断价值最高。结论不同SLP具有不同的超声造影表现,增强速度和增强模式的差异对于SLP的鉴别诊断具有重要价值。Objective To investigate the value of contrast-enhanced ultrasound in the differential diagnosis of solid lesions of pancreas（SLP）.Methods We retrospectively analyzed the clinical data of 54 SLP examined with contrast agent combined with contrast-enhanced ultrasound.Results The surrounding pancreas parenchyma enhancement time,lesion enhancement time,and peak enhancement time between different groups of SLP had no significant differences（P0.05）.When using the enhancement speed as a diagnostic indicator to different pancreatic carcinoma from tumor-like pancreatitis,the sensitivity,specificity,and accuracy were 92.3%,73.3%,and 87.0% for pancreatic carcinoma and 77.8%,97.8%,and 94.4% for tumor-like pancreatitis.When using the enhancement pattern as a diagnosis indicator to differentiate pancreatic carcinoma from tumor-like pancreatitis,the sensitivity,specificity,and accuracy were 92.3%,86.7%,and 90.7% and for pancreatic carcinoma and 77.8%,100%,96.3% for tumor-like pancreatitis.The diagnostic value of the enhancement pattern was best.Conclusions Different SLP shows different enhancement findings on contrast-enhanced ultrasound.The enhancement pattern and enhancement speed are the most useful diagnostic indicators.
