摘要: 目的 分析FibroScan检测联合电子计算机断层扫描(CT)检测肝脾CT值 (CTL/S) 比值诊断非酒精性脂肪性肝病(NAFLD)患者肝内脂肪变程度的价值。方法 2023年1月~2025年6月我院诊治的NAFLD患者106例,均行肝活检组织病理学检查,行CT检查测量肝脏和脾脏CT值,计算CTL/S比值,使用FibroScan行肝脏硬度检测(LSM)和受控衰减参数(CAP)检测,采用多元线性回归分析评估CAP和CTL/S比值与NAFLD患者肝脂肪变性程度的关联性,应用受试者工作特征(ROC)曲线线性分析指标诊断NAFLD患者重度肝脂肪变性的效能。结果 肝组织学检查诊断轻度肝脂肪变32例,中度39例,重度35例;重度组体质指数、腰臀比、LSM和CAP分别为(29.3±2.1)kg/m2、(1.3±0.4)、(10.1±1.4)kPa和(327.6±32.0)dB/m,均显著高于中度组【分别为(26.0±2.2)kg/m2、(1.1±0.2)、(8.4±1.2)kPa和(288.7±27.6)dB/m,P<0.05】或轻度组【分别为(24.7±2.1)kg/m2、(0.9±0.1)、(7.5±1.3)kPa和(265.8±25.9)dB/m,P<0.05】,而CTL/S比值为(0.5±0.1),显著低于中度组【(0.6±0.1),P<0.05】或轻度组【(0.7±0.1),P<0.05】;采用多元线性回归分析发现NAFLD患者肝脂肪变性程度与CAP呈正向关联(β=0.366,95%CI 0.148~0.687,P=0.006),与CTL/S比值呈负向关联(β=-0.235,95%CI -0.101~0.393,P=0.015);ROC曲线分析显示,CAP联合CTL/S比值诊断NAFLD患者重度肝脂肪变性的AUC为0.880,95% CI为0.809~0.950,其敏感性为80.0%,特异性为74.6%。结论 应用CTL/S比值与CAP联合诊断NAFLD患者肝脂肪变性程度具有较大的临床价值,可帮助临床筛查、指导临床干预决策。

Abstract: Objective The aim of this study was to investigate diagnostic efficacy of FibroScan and liver-spleen CT (CTL/S) ratio combination in predicting hepatic steatosis in patients with nonalcoholic fatty liver disease (NAFLD). Methods 106 patients with NAFLD were enrolled in our hospital between January 2023 and June 2025, and they all received liver biopsy for pathological examination, FibroScan for liver stiffness measurement (LSM) and controlled attenuation parameter (CAP), and CT scan for CTL/S ratio. Multivariate linear regression analysis was applied to evaluate the correlation between FibroScan parameters, CTL/S ratio and hepatic steatosis in patients with NAFLD. Receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic performance of FibroScan parameters and CTL/S ratio in predicting severe hepatic steatosis. Results Liver histo-pathological examination found mild hepatic steatosis in 32 cases, moderate in 39 cases and severe in 35 cases; body mass index, waist-to-hip ratio, LSM and CAP in patients with severe liver steatosis were (29.3±2.1)kg/m2, (1.3±0.4), (10.1±1.4)kPa and (327.6±32.0)dB/m, all significantly higher than [(26.0±2.2)kg/m2, (1.1±0.2), (8.4±1.2)kPa and (288.7±27.6)dB/m, respectively, P<0.05] in those with moderate liver steatosis or [(24.7±2.1)kg/m2, (0.9±0.1), (7.5±1.3)kPa and (265.8±25.9)dB/m, respectively, P<0.05] in those with mild liver steatosis, while CTL/S ratio was (0.5±0.1), significantly lower than [(0.6±0.1), P<0.05] in those with moderate or [(0.7±0.1), P<0.05] in those with mild liver steatosis; multivariate linear regression analysis found CAP was positively correlated to(β=0.366, 95%CI 0.148-0.687, P=0.006), while CTL/S ratio was negatively correlated to liver steatosis(β=-0.235, 95%CI -0.101-0.393, P=0.015); ROC analysis showed that the AUC was 0.880 (95% CI:0.809-0.950), with sensitivity of 80.0% and specificity of 74.6%, when CAP was combined with CTL/S ratio in predicting severe liver steatosis in patients with NAFLD. Conclusion CTL/S ratio and CAP combination is helpful in screening liver steatosis in patients with NAFLD, which might guide clinicians take appropriate measures for intervention.
