摘要
目的探讨MRI增强扫描在辽宁阜新地区肝脏坏死结节鉴别诊断中的应用价值。方法研究时间为2015年5月-2018年5月,采用回顾性研究方法,选择在我院诊治的肝脏坏死结节患者80例,所有患者均给予MRI常规与增强扫描,记录患者的影像学诊断与病理学特征。结果在80例患者中,70例为单发,10例为多发,T2WI扫描动脉期、静脉期主要表现为高信号,延迟期主要表现为低信号与等信号; MRI增强扫描鉴别诊断肝脏坏死良恶性结节的敏感性与特异性分别为98.5%和80.0%。MRI T2WI曲线下面积AUC=0.858,可信区间(0.754,0.962);增强扫描DCEI曲线下面积=0.898,可信区间(0.800,0.991);两者联合曲线下面积=0.982,可信区间(0.956,1.009),联合诊断的曲线下面积显著高于单独诊断(P<0.05)。结论 MRI增强扫描在辽宁阜新地区肝脏坏死结节中的应用具有很好的鉴别诊断价值,提高了MRI对肝脏坏死结节的诊断效能。
Objective To explore the value of MRI enhanced scanning in differential diagnosis of hepatic necrotic nodules in Fuxin. Methods The clinical data on eighty patients with hepatic necrotic nodules treated at our hospital between May 2015 and May 2018 was retrospectively studied.These patients were given MRI routine and enhanced scan,while their diagnostic and pathological features were recorded. Results Among the eighty cases,there were 70 cases of single nodules,and 10 cases of multiple nodules.In the arterial phase and venous phase of T2WI scan,signals were mostly high,while the delay period was dominated by low signals and equal signals. The sensitivity and specificity of MRI enhanced scan during differential diagnosis of benign and malignant nodules of liver necrosis were 98.5% and 80% respectively. The area under the MRI T2WI curve was 0.858,the confidence interval was（ 0.754,0.962）,compared with 0.898 and（ 0.800,0.991） under the enhanced scan DCEI curve,and0.982 and（ 0.956,1.009） under the combined method,so the difference between the three approaches was statistically significant（ P〈0.05）. Conclusion The application of MRI enhanced scan in the hepatic necrotic nodules is of great value for differential diagnosis,which can improve the diagnostic efficiency.
