肝硬变是一个重要的、日益严重的公共卫生问题,影响着数以百万计的美国人和国际上更多的人。发展为肝硬变的一个病理标志是肝纤维化的发展,因此监测肝纤维化的出现和进展可以用来指导治疗。我们报告了一种使用磁化标记磁共振成像(MRI)来测量心脏引起的肝脏运动和变形的方法,作为一种无创性评估与纤维化相关的肝脏僵硬的手段。初步结果显示,在通过心动周期直接比较最大位移(Mm)、最大(P1)和最小(P2)2D应变(分别为3.514±0.793,2.184±0.611;0.116±0.043,0.048±0.011;−0.094±0.020,−0.041±0.015;健康组,肝硬化组;P&lt0.005)方面,健康受试者和肝硬化组之间的差异有统计学意义。位移标准化的P1和P2菌株(mm−1)也有显著差异(分别为0.030±0.008,0.017±0.007;−0.024±0.006,−0.013±0.004;健康,肝硬变;P<0.005)。因此,这种基于非侵入性成像的方法是一种很有前途的方法,可以使用临床可用的成像工具来评估肝脏硬度。
Cirrhosis is an important and growing public health problem, affecting millions of Americans and many more people internationally. A pathological hallmark of the progression to cirrhosis is the development of liver fibrosis, so that monitoring the appearance and progression of liver fibrosis can be used to guide therapy. We here report a method to use magnetization-tagged magnetic resonance imaging (MRI) to measure the cardiac-induced motion and deformation in the liver, as a means for noninvasively assessing liver stiffness, which is related to fibrosis. The initial results show statistically significant differences between healthy and cirrhotic subjects in the direct comparisons of the maximum displacement (mm), and the maximum (P1) and minimum (P2) 2D strains, through the cardiac cycle (3.514 ± 0.793, 2.184 ± 0.611; 0.116 ± 0.043, 0.048 ± 0.011; −0.094 ± 0.020, −0.041 ± 0.015; healthy, cirrhosis, respectively; p < 0.005 for all). There are also significant differences in the displacement-normalized P1 and P2 strains (mm−1) (0.030 ± 0.008, 0.017 ± 0.007; −0.024 ± 0.006, −0.013 ± 0.004; healthy, cirrhosis, respectively; p < 0.005 for all). Therefore, this noninvasive imaging-based method is a promising means to assess liver stiffness using clinically available imaging tools.
