【摘要】：目的探讨不同类型肝泡型包虫病(AE)病灶边缘区CEUS参数特点。方法对45例患者48个肝AE的病灶行常规超声检查并分为浸润型、液化型和钙化型,后行CEUS检查,绘制时间-强度曲线,并分别记录不同类型肝AE病灶的中心区、边缘区和周围正常区的CEUS定量参数,包括峰值强度(pI)、达峰时间(Tp)、曲线下面积(AUC)、平均渡越时间(MTT),并进行统计学分析。结果浸润型、钙化型和液化型病灶边缘区pI、Tp和MTT差异有统计学意义(F=8.832、9.088、5.538,P均0.01),AUC差异无统计学意义(F=2.957,P=0.062)。浸润型与液化型、钙化型与液化型pI、Tp和MTT比较差异有统计学意义(P均0.01),浸润型与钙化型pI、Tp和MTT差异无统计学意义(P均0.05)。病灶中心区和周围正常区的pI、Tp、AUC和MTT差异均无统计学意义(P均0.05)。结论不同类型肝AE病灶的边缘区CEUS参数特点不同,浸润型和钙化型肝AE病灶的边缘区血液供应较液化型更丰富。
[Abstract]:Objective to investigate the characteristics of CEUS parameters in the marginal region of different types of hepatic alveolar hydatidosis. Methods Forty-eight liver AE lesions in 45 patients were examined by conventional ultrasound and classified into infiltrating type, liquefaction type and calcification type, and then CEUS was performed. The time-intensity curves were drawn and the quantitative parameters of CEUS were recorded in the central, marginal and surrounding normal areas of different types of liver AE lesions. These include peak intensity, peak time, area under the curve, MTT, and statistical analysis. There were significant differences in P _ I _ T _ p and MTT between calcified and liquefaction lesions. There was no significant difference in AUC between infiltrating type and liquefaction type, and there was no significant difference in AUC between infiltrating type and liquefaction type, there was no significant difference in AUC between infiltrating type and liquefaction type, there was no significant difference in AUC between infiltrating type and liquefaction type, and there was no significant difference in AUC between calcified type and liquefaction type. There was significant difference between calcified type and liquefaction type (P < 0.01), but there was no significant difference between infiltrating type and calcified type (P < 0.05). Conclusion the characteristics of CEUS parameters in the marginal region of different types of AE liver lesions are different. The peripheral blood supply of AE lesions in infiltrating and calcified liver is more abundant than that in liquefaction.
