摘要
目的：探讨超声造影结合时间-强度曲线（TIC）在鉴别胰腺局灶性占位性病变良恶性中的应用价值。方法：对40例疑有胰腺占位性病变的患者进行超声造影检查，作TIC分析，获得以下定量参数：曲线下面积、达峰时间及梯度。结果：良性组中胰腺病灶与病灶周围胰腺实质的达峰时间、梯度、曲线下面积之间比较，差异均无统计学意义（P>0.05）。恶性组中胰腺病灶与病灶周围胰腺实质的达峰时间比较，差异无统计学意义（P>0.05）；曲线下面积、梯度之间的比较，差异有统计学意义（P<0.05）。结论：不同病理类型胰腺局灶性占位性病变的超声造影定量参数存在差异，超声造影定量分析技术可以对胰腺局灶性占位性病变进行量化分析，并有较好的临床应用价值。
Abstract
Objective: To investigate the value of enhanced ultrasound in the differential diagnosis of focal pancreatic benign and malignant lesions. Methods: Enhanced ultrasound were performed in 40 patients suspected of pancreatic mass. The images were correlated with pathologic specimens. From the analysis of time to intensity curve(TIC), the following quantitative data were obtained: area under TIC; time to peak(TP) in different pathologic type of pancreatic lesions, and the gradient(GRAD) between effective contrast peak to the maximum peak. Results: In the benign group, there were no significant differences of area under curve, and GRAD between pancreatic tumor and parenchyma around the lesion(P>0.05). In the malignant group, there was no significant difference of the TP between the tumor and the surrounding paranchymal tissue, but there were significant differences of the area under curve and GRAD(P<0.05). Conclusion: In different pathologic type of focal pancreatic lesions the quantitative parameters of contrast ultrasound were different, quantitative analysis of enhanced ultrasound examination has better clinical value in the differential diagnosis between benign and malignant focal pancreatic lesions.
