目的 研究局限性脂肪肝发生部位.形态.密度及鉴别诊断方法,提高对该病的认识。资料和方法筛选40例CT平扫及强化扫描的脂肪肝病例,通过CT值的测量及肝内血管相对密度分级标准[1],结合强化CT表现进行诊断。结果:40例中有29例按肝段分布(72.2%),10例按肝叶分布(22.2%),1例呈球形(2.2%)。40例平扫均示肝血管湮没,10例呈血管反转。强化扫描均示密度轻度升高,其内血管影清晰,走行正常。结论:用CT值.血管相对密度变化,结合强化扫描对局限性脂肪肝有较高的诊断价值。
Abstract:
Objective : To study the fatty liver of limitation of the location, shape, density and the differential diagnosis methods. Methods : 40 cases fatty liver of limitation were riddled and the plain and enhanced CT was performed. To diagnosis using CT number and the criteria of relative density of hepatic vessels and postcontrast display. Results : In 40 cases, 29 cases were distributed by the segment of liver(72.2%),10 cases were distributed by the leaf of liver (22.2%), 1 cases was spherical (2.2%). All of the cases were appearance of hepatic vessels immersion. 10 cases were appearance of reverse hepatic vessels. The density was risen of light and the vessels was clear. Conclusion : Using CT number, the criteria of relative density of hepatic vessels and the relative density is of great value in the diagnosis of the fatty liver of limitation.
