急性肝损伤不同时间声像图特征分析

目的 探讨急性肝损伤不同时间B型超声检查的声像图特征。方法 将126例急性肝损伤声像图按不同检查时间分为A，B两组：A组为伤后25－50min检查，B组为伤后60－120min检查，并对A，B两组急性肝损伤声像图特征进行比较分析。结果 A，B两组的声像图分类构成差异有显著性意义，A组的高回声型明显高于B组，而组的混合性回声型明显高于A组（P＜0．001），A，B两组分别与同组各类型声像图比较，A组的高回声型和B组的混合性回声型均分别高于同期其它类型，差异有显著性意义（P＜0．001），结论 急性肝损伤因超声检查时间的不同声像图会有很大不同，最早表现以高回声型为主，然后向混合性回声型转变。

Analysis of ultrasonographic feature of acute hepatic lesions in different times

Objective　To study the ultrasound image feature of acute hepatic lesions in different times.Methods　The feature of ultrasonography in 126 cases with acute hepatic lesions were analyzed and divided into two groups according to different fime after injury: group A, 25～60 minutes after injury; group B, 60～120 minutes after injury.Results　There was significant difference in the structure of sonographic classification between two groups. The high echos was obviously higher in group A than that in group B, while the mixed echos was obviously higher in group B than that in group A (P<0.001). Compared each types in group A and in group B,the high achos in group A and the mixed achos in group B were higher than other types in same group (P<0.001).Conclusions　The ultrasonographic feature of acute hepatic lesions would change with time. The high echos occurs in eaily time after injury ,and then changes into the mixed echos.
