摘要
目的探究MRI与螺旋CT在肝硬化结节和小肝癌鉴别诊断中的应用价值。方法选择40例肝硬化或疑似小肝癌患者为研究对象,其均接受MRI、螺旋CT检查,以病理检查的结果为金标准,比较两种检查方式的应用价值。结果MRI诊断小肝癌的灵敏度、特异度、准确度均高于螺旋CT(P<0.05)。MRI对小肝癌诊断在肝动脉期,37.04%患者病灶为高-低-低信号,11.11%为高-等-等信号,44.44%为高-等-低信号,7.41%病灶未检出。螺旋CT对小肝癌诊断在肝动脉期,61.54%的患者病灶均匀强化,26.92%不均匀强化,11.54%未出现明显强化;在门静脉期,80.77%患者病灶为低密度,3.85%为稍高密度,15.38%为等密度;在延迟期,76.92%患者病灶为低密度,15.38%为等密度,7.69%为稍高密度。MRI对肝硬化诊断,T1WI序列为稍低密度或稍高密度,动态增强扫描动脉期为均匀增强的高信号,在门静脉期或延迟期为低信号。肝硬化患者经螺旋CT检查,其病灶处的密度低,边界清晰,实施双期增强扫描,可见病灶不均匀强化的情况,在门静脉期病灶为等密度。结论MRI、螺旋CT在肝硬化结节和小肝癌鉴别诊断中均具有一定的应用价值,但MRI可更好地检出疾病,为疾病的确诊以及治疗方案的制定提供参考依据。
Objective To explore the application value of MRI and spiral CT in differential diagnosis of liver cirrhosis nodules and small hepatocellular carcinoma.Methods A total of 40 patients with liver cirrhosis or suspected small hepatocellular carcinoma were selected as the research objects.All patients underwent MRI and spiral CT examination.The application value of the two examination methods were analyzed with the results of pathological examination as the gold standard.Results The sensitivity,specificity and accuracy of MRI in diagnosing small hepatocellular carcinoma were higher than those of spiral CT(P<0.05).For the diagnosis of small hepatocellular carcinoma with MRI,in the hepatic artery stage,37.04%of the patients were diagnosed with high-low-low signal,11.11%with high-equal-equal signal,44.44%with high-equal-low signal,and 7.41%without detection.For the diagnosis of small hepatocellular carcinoma with spiral CT,in the hepatic artery stage,lesions in 61.54%of the patients were uniformly enhanced,26.92%were non-uniformly enhanced,and 11.54%showed no significant enhancement.In the portal vein stage,80.77%of the patients had low density lesion,3.85%had slightly high density,and 15.38%had equal density.In the delayed stage,76.92%of the patients had low densitylesion,15.38%had equal density,and 7.69%had slightly high density.In the diagnosis of liver cirrhosis by MRI,T1WI sequence was slightly low density or slightly high density,high signal of uniform enhanced in arterial stage and low signal in portal vein stage or delayed stage.Spiral CT examination showed that the low density of lesion and the clear boundary in patients with liver cirrhosis.Double-phase enhanced scan showed that the lesion was not uniformly enhanced,and the lesion was of equal density at the portal vein stage.Conclusion MRI and spiral CT have certain application value in the differential diagnosis of liver cirrhotic nodules and small hepatocellular carcinoma.However,MRI can better detect the disease and provide reference for the diagnosis of the disease and the formulation of treatment plan.
