摘　　要：目的探讨轻度脂肪肝的CT特征,总结诊断经验。方法采用回顾性的分析方法,选取2011年2月-2012年4月某院收治确诊为脂肪肝患者共142例作为研究对象,行CT扫描,获得肝、脾CT值,并取比值,对比弥漫性脂肪肝与局灶性脂肪肝的CT特征,就轻度脂肪肝特征进行分析。结果共诊断出轻度脂肪肝74例占52.11%,其中弥漫性脂肪肝63例,无占位效应,病灶分布均匀,局灶性脂肪肝11例,病灶分布特异,有占位效应;轻度脂肪肝患者人均肝脏CT值(47.29±8.21)HU,肝、脾CT比值(0.75±0.11)。结论轻度脂肪肝患者其肝脏密度较中度、重度患者更高,弥漫性脂肪肝诊断较易,局灶性脂肪肝诊断,部分患者需进行增强扫描、增添对比剂或延时扫描,以排除肝癌、肝血管瘤等占位性病变的可能。[ Objective ] To study the mild fatty liver CT characteristics,summarizes the experience in diagnosis. [ Methods ] A retrospective analysis of the methods to select 2011 2 to a hospital in April 2012,a total of 142 patients with diagnosis of fatty liver were as the research object,CT scan,liver,spleen and CT value,compare the density value,contrast diffuse fatty liver and focal fatty liver CT features,analysis the characteristic on mild fatty liver. [ Results ] 74 cases with mild diagnosis of mild fatty liver were 52.11%,of which 63 cases of diffuse fatty liver,no placeholder effect,even,to the distribution of focal fatty liver in 11 cases,specific to the distribution of, a placeholder effects; Mild fatty liver in patients with liver CT value （47.29 ± 8.21） per capita HU,liver,spleen CT ratio（0.75 ± 0.11）. [ Conclusion ] Mild fatty liver patients with moderate and severe patients to reduce the liver density is not significant,diffuse fatty liver diagnosis more easily,focal fatty liver diagnosis part need to add contrast enhancement scan,agent or delay scan,to eliminate type placeholder lesions such as liver cancer,liver hemangioma.
