摘要：

【摘要】目的探讨超声诊断脂肪肝同MRI、CÞ相对比的优势及劣势。方法选取我院行肝脏穿刺活检或部分肝切除证实的脂肪肝患者40例，设为观察组；同时选取同期健康体检志愿者40例，设为对照组；两组均给予超声、CÞ及MRI检查，观察比较两组超声、CÞ、MRI图像特点，以多变量指标定量或半定量方法对肝脏脂肪含量（LFC）进行测定，同时将病理检查作为对照，进行综合比较。结果本次研究中，40例脂肪肝患者CÞ检查的诊断准确率为9².5%，超声检查准确率85%，MRI检查准确率65.0%，数据分析可以得出，在准确率比较上，超声与CÞ检查基本无差异，P>0.05；CÞ和超声准确率均高于MRI，差异具有统计学差异（P<0.05）；观察组的肝实质平均灰度值（LPGS）、肝静脉平均灰度值（HVGS）及肝脏相对回声强度（REI）均明显高于对照组，且观察组的（LPGS/PVGS）比值低于对照组，结果具有统计学差异（P<0.05）。结论脂肪肝的影像学检查主要是超声和CÞ，而MRI的检出率较低；脂肪肝B超检查的诊断率虽然低于CÞ检查，但其敏感性较高，操作便捷无放射性损伤，临床检测费用较低，推广使用价值大。
