【摘要】：目的探讨CEUS对肝脏局灶性脂肪浸润或缺失的诊断价值。方法回顾性分析76例肝脏局灶性脂肪浸润或缺失病例,其中3例经病理学证实,73例经增强CT/增强MRI确诊并随访6个月以上。所有病例均接受常规二维超声及CEUS检查。结果 76例病例中,71例(71/76,93.42%)表现为动脉期、门静脉期及实质期三期等增强,4例(4/76,5.26%)表现为动脉期轻度高增强、门静脉期及实质期等增强,1例(1/76,1.32%)类似肝癌的动脉期高增强、门静脉期及实质期低增强。CEUS诊断局灶性脂肪浸润或缺失与病理或其他检查随访结果的差异无统计学意义(P=0.0625),二者具有相关性(r=0.65,P0.001)。二维声像图上三期等增强组与动脉期高增强组病灶回声、边界和形态的差异均无统计学意义(P均0.05)。结论 CEUS对局灶性脂肪浸润或缺失的诊断具有较高的准确率。
[Abstract]:Objective to investigate the diagnostic value of CEUS in focal fatty infiltration or loss of liver. Methods 76 cases of hepatic focal fat infiltration or loss were retrospectively analyzed. 73 cases were confirmed by enhanced CT/ enhanced MRI and followed up for more than 6 months. All cases were examined by conventional two-dimensional ultrasound and CEUS. Results among 76 cases, 71 cases (71 / 76 93.42%) showed arterial phase, 4 cases (4 / 765.26%) showed enhanced arterial phase, 1 case (1 / 71.32%) showed arterial hyperintensity in portal and parenchymal phase, 1 / 71.32% (1 / 71.32%) showed high enhancement in arterial phase similar to hepatocellular carcinoma, 4 cases (4 / 765.26%) showed mild hyperenhancement in arterial phase. There was no significant difference in the diagnosis of focal fat infiltration or deletion between portal vein phase and parenchymal phase (P < 0.0625), but there was a correlation between them (r 0.65% P 0.001). There was no significant difference in echo, boundary and morphology between the three phase enhancement group and the arterial phase high contrast group (P 0.05). Conclusion CEUS has a high accuracy in the diagnosis of focal fat infiltration or loss.
