肝脾损伤的MSCT及其血管成像与彩色超声对照性研究

目的探讨MSCT及其血管成像与彩超在肝、脾损伤诊断中的临床应用价值。方法收集外伤性肝、脾损伤病例36例，分析CT征象并与彩色超声对照，探讨两种检查方法的优势。结果肝损伤17例，其中肝实质损伤9例，肝包膜下血肿6例；肝实质损伤合并包膜下血肿2例。脾损伤19例，其中实质损伤9例，包膜下血肿10例。MSCT与彩色超声的诊断符合率分别为95％和89％，经配对资料的Χ^2检验，结果有统计学意义（Χ^2=16.941，P〈0．05）。结论MSCT及其血管成像较彩超更立体、直观地显示肝、脾损伤的程度和范围，为临床诊断和制定治疗方案提供可靠的依据。

The comparative study between multi-slice spiral CT angiography and color flow ultrasonography in hepatic and splenic trauma

Objective To investigate the clinical vahle of multi-slice spiral CT angiography and color flow ultra- sonography in hepatic and splenic trauma. Methods Thirty-six cases of hepatic and splenic trauma were collected, the MSCT were analyzed and compared with that of color flow ultrasonography. Results Seventeen cases were Hepatic trauma including nine cases of hepatic contusion, six cases of sub-envelope hematoma, two cases of both sub-envelope hematoma and hepatic contusion. Nineteen cases were splenic trauma including nine cases of splenic contusion, ten cases of sub-envelope hematoma. Conclusion Multi-slice spiral CT angiography show hepatic and splenic trauma clearer than that of color flow ultrasonography, and can provide reliable basis for clinic diagnosis and therapy.
