目的:探讨非均匀性脂肪肝超声声像图特点。方法:对2009年1～12月60例非均匀性脂肪肝患者应用西门子Prima二维凸阵成像仪,探头2.6～5.0 MHz;东芝32B线阵成像仪,探头3.5 MHz进行检查。结果:声像图表现为肝内可见大小不等回声异常区,边界清晰;内部回声多数均匀,为强回声,管状结构变细或显示不清,病灶无球体感,无明显声晕,无占位效应。合叶段型脂肪肝48例,团块型脂肪肝12例。结论:局灶性脂肪肝的超声诊断有其声像图特点,可以比较准确地进行诊断,且操作简便、检查无创,是诊断首选方法之一。
Objective: To investigate the characteristics of non-uniform fatty liver ultrasound sonography. Methods: Sixty patients with non-uniform fatty liver from January to December 2009 were examined with Siemens Prima 2D convex array imager with a probe of 2.6-5.0 MHz and a Toshiba 32B linear array imager with 3.5 MHz probe. Results: The echogram showed a range of intrahepatic echo size ranging from the echo, the boundary is clear; the internal echo most uniform, strong echo, the tubular structure is thinner or unclear, no spherulitic lesions, no obvious sound halo, no accounting for Bit effect. There were 48 cases of hepatic segmental fatty liver and 12 cases of massive fatty liver. Conclusion: Ultrasound diagnosis of focal fatty liver has its sonographic features that can be more accurately diagnosed, and easy to operate, noninvasive examination is one of the preferred methods of diagnosis.
