超声造影与增强CT在诊断胰腺占位性病变的对比研究

Comparision of diagnostic value between contrast-enhanced ultrasound and contrast-enhanced CT for the pancreatic masses

目的评价超声造影与增强CT在诊断胰腺占位性病变的对比研究。方法 36例胰腺占位性病变患者分别行超声造影和增强CT检查,并根据病理检查或随访观察结果,比较两者的诊断符合率。结果超声造影和增强CT的诊断准确率分别为83.33%和86.11%,差异无统计学意义。36例患者中,2例局灶性胰腺炎超声造影均准确诊断,增强CT检查误诊为胰头癌。结论超声造影与增强CT在确诊胰腺占位性病变方面的价值相当。

Objective To evaluate the diagnosis value of contrast-enhanced ultrasonography （CEUS） and contrast- enhanced CT （CECT） for the pancreatic masses. Method Both CEUS and CECT were performed to 36 patients with pancreatic lesions. Data of pathological examination or follow-up images were collected. The diagnostic accuracy of CEUS and CECT were compared. Results The accuracy of CEUS and CECT were 83.3% and 86.1%, respectively, there was no significant difference was found between CEUS and CECT. However, among these cases, two patients with focal pancreatitis were misdiagnosed as pancreas cancer using CECT, while the CEUS diagnosed correctly. Conclusion The CEUS is as effective as CECT in the diagnosis of the pancreatic masses.
