急性闭合性肝损伤不同时期的超声声像图特征分析

Analysis of Ultrasonographic Characteristics in Different Periods of Acute Closed Hepatic Injuries

目的:探讨急性闭合性肝损伤不同超声检查时期声像图特征,以提高超声诊断水平。方法:将76例急性闭合性肝损伤声像图类型分为高回声型、混合性回声型、低或无回声型及回声正常,并按照不同检查时间将其分为A、B两组,就其声像图类型进行组内及组间比较。结果:急性闭合性肝损伤后随着就诊时间的不同,声像图表现亦不同,2h内就诊者声像图表现以高回声为主,2h以后就诊者声像图表现以混合性回声为主,两组内及组间比较差异均有显著意义(P<0.05)。结论:掌握这些声像图变化特征为迅速、及时诊断急性闭合性肝损伤提供独特的临床价值。

Objective： To investigate ultrasonographic characteristics in different periods of acute closed hepatic injuries for improving ultrasonic diagnosis accuracy. Methods：According to the examination time, 76 cases with acute closed hepatic injuries were divided into two groups：group A（n = 44） and group B （n = 32）, in which ultrasonography showed high - level echo, low - level echo, echoless and normal echo. The types of imaging among groups were compared. Results： The ultrasonographic types of acute closed hepatic injuries differed in examination time,showing high- level echo in 2 hours after injuries, mixing echo after 2 hours of injuries. There were significant differences in both groups or between them （ P 〈 0.05）. Conclusion： Ultrasonography is valuable for promptly diagnosis of acute closed hepatic injuries.
