超声造影在脾外伤评估及分级诊断中的临床应用

目的探讨常规超声与超声造影在脾外伤评估和分级诊断中的应用价值。方法对42例经CT和（或）手术证实为脾外伤患者的常规超声和超声造影检查资料进行对比分析。结果42例脾外伤常规超声检出28例，漏诊14例（轻重不同程度各7例）；超声造影检出40例，漏诊2例（均为轻微损伤）。超声造影在损伤灶检出率和分级方面明显优于常规超声（P〈0．001）。在42例脾外伤程度分级诊断中，常规超声组存在明显级别低估者10例；超声造影组无一例发生级别低估，且与CT和（或）手术组脾外伤程度分级诊断结果基本一致。结论超声造影在脾外伤检出率及脾外伤程度分级评估上明显优于常规超声，基本与手术或（和）CT检出率和评估结果一致。超声造影与常规超声诊断脾外伤相比，是一项新的技术突破，具有重要的临床应用价值。

Contrast-enhanced ultrasonography in evaluation of splenic trauma and injury grading and its clinical apllication

Objective To evaluate the conventional ultrasound(US)and contrast-enhanced ultrasound(CEUS)in diagnosis of splenic trauma including its grading diagnosis.Methods US and CEUS in 42 patients with splenic trauma confirmed by CT and/or operation were performed during 9.2004-10.2007.All the data were compared and analyzed retrospectively.Results Of 42 patients with splenic trauma,28 cases were detected and 14 cases were missed on US examination,whereas,40 cases were detected and only 2 mild cases were missed on ...
