| 目的 采用CEUS观察肝外胆管癌(ECC)的灌注过程及增强特点。方法 收集经病理证实的55例ECC患者。先行常规超声检查,再启动实时CEUS成像技术模式,评估分析病灶的增强方式、始增时间,并与常规超声比较诊断准确率。结果 CEUS的诊断准确率(52/55,94.55%)高于常规超声(44/55,80.00%;χ2=5.24,P<0.05)。不同类型病灶造影增强方式构成比差异有统计学意义(P<0.001),94.12%(16/17)厚壁型病灶为均匀增强,63.16%(12/19)团块型病灶为周边环形增强。不同类型病灶的始增时间构成比差异有统计学意义(P<0.001),94.12%(16/17)厚壁型病灶始增时间晚于肝脏/胆管壁始增时间,63.16%(12/19)团块型病灶始增时间早于肝脏/胆管壁始增时间。结论 采用CEUS可以提高ECC的诊断准确率,不同类型ECC的始增时间和增强方式有其特征性,值得临床推广及应用。 |

| Objective To evaluate the contrast perfusion and enhancement patterns of extrahepatic cholangiocarcinoma (ECC) with CEUS. Methods Totally 55 ECC patients confirmed by pathology were enrolled. All patients underwent conventional ultrasound firstly, then CEUS was performed. The diagnostic accuracy of CEUS was compared with conventional ultrasound. Results The diagnostic accuracy of CEUS (52/55, 94.55%) was higher than that of conventional ultrasound (44/55, 80.00%; χ2=5.24, P<0.05). The enhancement mode differed in tumor types (P<0.001), 94.12% (16/17) of the thick-wall masses were homogeneously enhanced, while 63.16% (12/19) of the block-shaped masses got rim-like enhancement. The contrast arrive time differed in tumor types (P<0.001), 94.12% (16/19) of the thick-wall masses enhanced later than the normal liver/bile duct wall; while 63.16% (12/19) of the block-shaped masses enhanced earlier than the normal liver/bile duct wall. Conclusion Different tumor types have certain characteristics of enhancement mode and contrast arrive time. CEUS can improve the diagnostic accuracy of ECC and deserve clinical promotion. |
