Abstract
Background & Aims

Establishing accurate non-invasive methods of liver fibrosis quantification remains a major unmet need. Here, we assessed the diagnostic value of a multiparametric magnetic resonance imaging (MRI) protocol including diffusion-weighted imaging (DWI), dynamic contrast-enhanced (DCE)-MRI and magnetic resonance elastography (MRE) in comparison with transient elastography (TE) and blood tests [including ELF (Enhanced Liver Fibrosis) and APRI] for liver fibrosis detection.
Methods

In this single centre cross-sectional study, we prospectively enrolled 60 subjects with liver disease who underwent multiparametric MRI (DWI, DCE-MRI and MRE), TE and blood tests. Correlation was assessed between non-invasive modalities and histopathologic findings including stage, grade and collagen content, while accounting for covariates such as age, sex, BMI, HCV status and MRI-derived fat and iron content. ROC curve analysis evaluated the performance of each technique for detection of moderate-to-advanced liver fibrosis (F2–F4) and advanced fibrosis (F3–F4).
Results

Magnetic resonance elastography provided the strongest correlation with fibrosis stage (r = 0.66, P < 0.001), inflammation grade (r = 0.52, P < 0.001) and collagen content (r = 0.53, P = 0.036). For detection of moderate-to-advanced fibrosis (F2–F4), AUCs were 0.78, 0.82, 0.72, 0.79, 0.71 for MRE, TE, DCE-MRI, DWI and APRI, respectively. For detection of advanced fibrosis (F3–F4), AUCs were 0.94, 0.77, 0.79, 0.79 and 0.70, respectively.
Conclusions

Magnetic resonance elastography provides the highest correlation with histopathologic markers and yields high diagnostic performance for detection of advanced liver fibrosis and cirrhosis, compared to DWI, DCE-MRI, TE and serum markers.

抽象
背景和目的

建立肝纤维化定量准确的非侵入性的方法仍然是一个重大的未满足的需要。这里,我们评估包括扩散加权成像(DWI),动态对比增强与瞬时弹性比较(DCE)-MRI和磁共振弹性(MRE)(TE)多参数磁共振成像(MRI)的协议的诊断价值和血液化验[包括ELF(增强肝纤维化)和APRI]肝纤维化检测。
方法

在这种单中心横断面研究中,我们前瞻性纳入60例肝病患者谁接受MRI多参数(DWI,DCE-MRI和MRE),TE和验血。相关性的非侵入性的方式和组织病理学结果包括分期,分级和胶原含量之间分摊,而占协变量,例如年龄,性别,BMI,丙型肝炎病毒的状态和MRI源性脂肪和铁含量。 ROC曲线分析评估每种技术检测中度至晚期肝纤维化(F2-F4)和晚期肝纤维化(F3-F4)的性能。
结果

磁共振弹性设置有纤维化分期相关(r = 0.66,P <0.001),炎症等级相关(r = 0.52,P <0.001)和胶原蛋白含量相关(r = 0.53,p = 0.036)相关性最强。对于检测中至晚期纤维化(F2-F4)的,分别的AUC 0.78,0.82,0.72,0.79,0.71 MRE,TE,DCE-MRI,DWI分别APRI和。为了检测晚期肝纤维化(F3-F4)的AUC分别为0.94,0.77,0.79,0.79分别和0.70。
结论

磁共振弹性提供了组织病理学标志物的相关性最高,并产生用于检测晚期肝纤维化和肝硬化高诊断性能,相比DWI,DCE-MRI,TE和血清标志物。
