摘要
目的:观探讨磁共振成像(MRI)与超声弹性成像(UE)在肝纤维化诊断价值差异。方法:选取112例慢性乙肝患者并采用超声弹性成像、磁共振检查和超声引导下穿刺活检术,以病理检查作为诊断金标准,评估UE、MRI对肝纤维化的诊断价值。结果:UE对肝纤维化的诊断灵敏度、特异度、阳性预测值、阴性预测值和准确度为92.00%、83.78%、92.00%、83.78%和89.29%;而MRI则为80.00%、89.19%、93.75%、68.75%和83.04%,两者灵敏度和阴性预测值比较差异具有显著性(P<0.05),UE诊断准确率较高,但比较无显著性(P>0.05)。结论:超声弹性成像对肝纤维化诊断灵敏度和准确率优于磁共振成像。
Objective： To study the comparison on liver fihros resonance imaging（MRl）.Methods：ll2 cases of chronic hepatitis B s diagnosis value of ultrasound elastosonography（UE） and magnetic patients were selected, all were given ultrasound elastosonography, magnetic resonance imaging and ultrasound guided biopsy, pathologic examination was as the diagnostic golden standard, the diagnosis value of UE, MRI in liver fibrosis were evaluated.Results：The sensitivity, specificity positive predictive value,negative predictive value and accuracy of liver fibrosis UE diagnosis were 92.00%, 83.78%, 92.00%, 83.78% and 89.29%,While MRI were 80.00%,89.19%,93.75 %,68.75% and 83.04%,thc sensitivity and negative predictive value compared with significant difference（P〈0.05）,UE diagnosis accuracy was higher, but had no significant （P〉O.O5）.Conclusion：The sensitivity and accuracy of ultrasound elastosonography for liver fibrosis diagnosis are better than magnetic resonance imaging.
