Abstract:
Objective To investigate the value of contrast-enhanced ultrasound (CEUS) in differential diagnosis of pancreatic pseudocysts,cystadenomas and cystadenocarcinomas,so as to improve diagnostic accuracy of the condition.Methods The results of CEUS and conventional ultrasound for 71 patients with pancreatic cystic lesions were analyzed retrospectively,and compared with the finally obtained surgical-pathological examination to assess the ability of qualitative diagnosis between two methods.Results In 71 pancreatic cystic lesions,there were 32 pancreatic pseudocysts,24 cystadenomas and 15 cystadenocarcinomas.The sensitivity and accuracy of CEUS for pancreatic pseudocysts and cystadenocarcinomas were 84.4％,93.0％ and 86.7％,88.7％,which were higher than those of conventional ultrasound 56.3 ％,80.3 ％ and 53.3 ％,74.6％ (x2 =6.06,4.92,3.97,4.71,all P ＜ 0.05).Conclusion There are some similarities in terms of imaging manifestations among pancreatic pseudocysts,cystadenomas and cystadenocarcinomas.Combining conventional ultrasound with CEUS can help the differential diagnosis of pancreatic cystic lesions.
