Abstract

Purpose

Three main non-invasive imaging methods are routinely used for the assessment of liver fibrosis and steatosis in patients with nonalcoholic fatty liver disease (NAFLD): the vibration-controlled transient elastography (VCTE) using the FibroScan device, the magnetic resonance imaging (MRI) based on proton density fat fraction (PDFF), and the magnetic resonance elastography (MRE). The purpose of our study is to evaluate the efficiency of the VCTE findings compared to the two others methods, and to analyze the impact of hepatic iron overload on these comparisons.

Methods

A clinical study was performed on 94 patients with NAFLD in the radiology department of ACRIM-Polyclinic Saint-Côme (France). The study also included 17 patients with hemochromatosis, measured from T2 MRI. The liver tissues of all the patients were evaluated with 1) VCTE (including the controlled attenuation (CAP) and stiffness parameters), 2) MRI (fat fraction parameter), and 3) MRE (stiffness parameter) techniques. The performance of VCTE was assessed by estimating the area under the ROC curve (AUC) for patients without or with hemochromatosis. Spearman's correlation was used for the comparison of VCTE measurements to MRI and MRE.

Results

VCTE-based stiffness and CAP were significantly correlated with PDFF and MRE measurements (P<0.01) for the subgroup without hemochromatosis. The correlations failed for the subgroup with hemochromatosis.

Conclusion

VCTE and CAP measurements were not correlated with those from MR PDFF and MRE for patients with hemochromatosis. VCTE, PDFF and MRE modalities don't give concordant results for patients with hemochromatosis.

应用振动控制瞬态弹性成像(VCTE)和MR成像技术评估非酒精性脂肪肝患者脂肪变性和纤维化时肝铁过载的影响:一项临床研究
目的常规使用三种主要的非侵入性成像方法来评估非酒精性脂肪肝(NAFLD)患者的肝纤维化和脂肪变性:使用FibroScan设备的振动控制瞬态弹性成像(VCTE)、基于质子密度脂肪分数(PDFF)的磁共振成像(MRI)和磁共振弹性成像(MRE)。我们研究的目的是评估与其他两种方法相比,VCTE结果的有效性,并分析肝脏铁过载对这些比较的影响。方法在法国圣科姆ACRIM综合医院放射科对94例NAFLD患者进行临床研究。该研究还包括17名血色素沉着症患者,通过T2 MRI测量。所有患者的肝组织均采用1)VCTE(包括控制衰减(CAP)和硬度参数)、2)MRI(脂肪分数参数)和3)MRE(硬度参数)技术进行评估。VCTE的性能是通过估计无或有血色素沉着症患者的ROC曲线下面积(AUC)来评估的。Spearman相关性用于比较VCTE测量值与MRI和MRE。结果对于没有血色素沉着症的亚组,基于VCTE的硬度和CAP与PDFF和MRE测量值显著相关(P<;0.01)。血色素沉着症亚组的相关性不成立。结论血色素沉着症患者的VCTE和CAP测量与MR-PDFF和MRE的测量不相关。VCTE、PDFF和MRE模式不能为血色素沉着症患者提供一致的结果。
