Eur Radiol:肝脏MR弹性成像是否可定量评价门脉高压症?

PHTN可导致许多重要的肝病后遗症,包括与高发病率和死亡率相关的严重静脉曲张出血。因此,早期评估PHTN对改善预后具有重要价值。

      门静脉系统压力的病理升高定义为门静脉高压(PHTN),是慢性肝病(CLD)和肝硬化患者并发症的关键驱动因素。PHTN可导致许多重要的肝病后遗症,包括与高发病率和死亡率相关的严重静脉曲张出血。因此,早期评估PHTN对改善预后具有重要价值。肝静脉压梯度(HVPG)的测量目前被作为诊断PHTN的金标准,但由于该方法为侵入性检查,因此在临床上难以常规开展。因此,有必要开发一种非侵入性技术来量化PHTN综合征的门静脉压力。


      双参数磁共振弹性成像(MRE)在检测PHTN上是一种很有前途的非侵入性技术。近日,发表在European Radiology杂志的一项研究应用双参数双频MRE预测两种不同小鼠模型的门静脉压力(PP),定量评价PHTN与肝纤维化程度的关系,确定双参数双频MRE预测PP的潜力。

      我们研究了73只野生型雄性小鼠,其中包括22只肝充血小鼠,20只胆汁淤积性肝损伤小鼠和31只年龄相匹配的假性对照小鼠。肝剪切硬度(SS)和体积应变(VS)通过在80和200 Hz下的3D MR下获得。 我们在MRE之后立即测量了PP。通过羟脯氨酸法证实肝纤维化。分别使用单频、双频SS和VS拟合广义线性模型来预测PP。通过Spearman的相关性评估预测PP与实际PP之间的关系。 我们用DeLong检验在0.05的显着性水平上比较了所有模型的门脉高压的预测准确性。

      患有充血性或胆汁淤积性肝病出现不同程度的明显PHTN和肝纤维化。与假性对照组相比,两种模型中SS显著增加,VS显著减少。所有双参数模型对PHTN均有较高的诊断准确率。双频模型(auc: 0.90[81-95%]、0.91[81-95%])的准确率明显高于单频模型(auc: 0.83[71-91%]、0.78[66-87%])。双频模型预测的PP值与实际PP值的相关性较单频模型更强。

  门静脉压力预测模型的ROC曲线   

      双参数双频模型提高了肝MRE在临床前模型诊断PHTN的准确性。这项技术具有监测不同肝纤维化条件下PHTN的进展和治疗效果的潜力。
