| 目的 比较常规超声与超声造影在胰腺癌及肿块型胰腺炎 (chronic mass pancreatitispancreatitis，CMP)的鉴别诊断价值，提高术前鉴别诊断率。方法 随机抽取2013年1月~2015年12月在我院行超声检查的胰腺癌及肿块型胰腺炎患者共60例作为研究对象，均用常规超声及超声造影（contrast-enhanced ultrasonography，CEUS）检查，使用统计学方法比较二者对胰腺肿块性质、灵敏度、特异性及超声显像等的差异性。结果 超声造影对胰腺癌及肿块性胰腺炎检出率高于常规超声，P<0.05；CUES对胰腺癌及肿块型胰腺炎的特异度及灵敏度均高于常规超声检查(P<0.05)；造影静脉期：胰腺癌不均质增强比例高于肿块型胰腺炎（P<0.01）；胰腺癌患者AT、TTP均大于肿块型胰腺炎（P<0.05），mTT两组比较差异无统计学意义，P>0.05。肿块型胰腺炎Imax与正常胰腺实质相近，胰腺癌患者Imax小于正常胰腺组及肿块型胰腺炎。结论 超声造影对于胰腺癌及肿块型胰腺炎的诊断及鉴别诊断较常规超声更加准确和客观，有较高的临床应用价值。 |

| Abstract: |
| Objective：To compare the value of 2D-US and CEUS in differential diagnosis of pancreatic carcinoma and chronic mass pancreatitis,in order to improve the diagnosis before surgery.Methods: Totally 60 patients with pancreatic carcinoma or chronic mass pancreatitis were diagnosised by both 2D and CEUS during Jan 2013 and Dec 2015. To copmare the sensitivity(Sen),specificity(Spe)and enhancement with statistical method.Results: It showed the sensitivity and specificity of CEUS grop were higher than that of 2D grop（P＜0.05）;CEUS showed inhomogeneous enhancement of pancreatic carcinoma were higher than that of chronic mass pancreatitis（P＜0.01） ; AT、TTP of pancreatic carcinoma were longer than that of chronic mass pancreatitis（P＜0.05）;It showed no statistic significant in mTT ;Imax of chronic mass pancreatitis was the same as that of nomal pancreatitis,Imax of pancreatic carcinoma was lower than that of nomal pancreatitis and chronic mass pancreatitis.Conclusion: In contrast to 2D,CEUS could provide objective and effective criterion for differential diagnosis of pancreatic carcinoma and chronic mass pancreatitis． |
