目的：探讨脂肪肝背景下肝血管瘤的多层螺旋CT表现特征。方法：回顾性分析本院98例经病理证实的肝血管瘤的影像资料,根据平扫是否有脂肪肝背景分为Ⅰ组(脂肪肝背景),Ⅱ组(无脂肪肝背景且无其他肝脏疾病),再根据CT增强表现分为A组(动脉期边缘结节样强化),B组(动脉期均匀强化),将Ⅰ、Ⅱ组及A、B组进行交叉归类统计分析。结果：肝血管瘤的CT平扫检出率为分别为Ⅰ组58.3％、Ⅱ组84.0％,Ⅰ、Ⅱ组之间差异具有统计学意义；增强CT检查：A组(ⅠA组、ⅡA组) CT增强诊断符合率100％,ⅠB组CT增强诊断符合率22.2％,ⅡB组CT增强诊断符合率88.9％,ⅠB组与ⅡB组之间差异具有统计学意义。结论：脂肪肝背景下,肝血管瘤病灶的相对密度会发生改变,但其强化方式及强化特征仍然符合肝血管瘤的经典诊断标准,对于少数表现不典型病例,则需要结合其他检查来减少误诊率。
目的：探討脂肪肝揹景下肝血管瘤的多層螺鏇CT錶現特徵。方法：迴顧性分析本院98例經病理證實的肝血管瘤的影像資料,根據平掃是否有脂肪肝揹景分為Ⅰ組(脂肪肝揹景),Ⅱ組(無脂肪肝揹景且無其他肝髒疾病),再根據CT增彊錶現分為A組(動脈期邊緣結節樣彊化),B組(動脈期均勻彊化),將Ⅰ、Ⅱ組及A、B組進行交扠歸類統計分析。結果：肝血管瘤的CT平掃檢齣率為分彆為Ⅰ組58.3％、Ⅱ組84.0％,Ⅰ、Ⅱ組之間差異具有統計學意義；增彊CT檢查：A組(ⅠA組、ⅡA組) CT增彊診斷符閤率100％,ⅠB組CT增彊診斷符閤率22.2％,ⅡB組CT增彊診斷符閤率88.9％,ⅠB組與ⅡB組之間差異具有統計學意義。結論：脂肪肝揹景下,肝血管瘤病竈的相對密度會髮生改變,但其彊化方式及彊化特徵仍然符閤肝血管瘤的經典診斷標準,對于少數錶現不典型病例,則需要結閤其他檢查來減少誤診率。

Objective:To investigate the MSCT features of hepatic hemangioma associated with fatty liver. Methods: The image data of 98 patients with hepatic hemangioma proved by pathology were retrospective analyzed. Through detecting whether they have fatty liver by unenhanced scan, the 98 patients were divided into group I ( with fatty liver) and group II ( without fatty liver or other liver diseases) , And then, they were assigned to group A ( edge nodular enhancement in arterial phrase) and group B ( homogeneous enhancement in arterial phrase) according to the enhanced CT performance. Cross classification and statistical analysis were processed among group I, group II and group A, group B. Results: The detection rate of hepatic hemangioma by unenhanced CT scan were 58. 3% ( group I) and 84. 0% ( group Ⅱ) respectively. And there was statistical significance between group I and group II. Enhanced CT scan showed that the diagnostic accordance rate was 100% in group A ( group IA, group IIA) , 22.2% in group IB, 88.9%. in group IIB respectively. And there was statistical significance between group IB and group IIB. Conclusion: Associated with fatty liver, the relative density of hepatic hemangioma may change. However, the modes and features of its enhancement still accord with typical diagnostic criteria. The combination with other detection is still needed for some untypical cases to reduce misdiagnosis rate.
