影像技术对非酒精性脂肪肝的评价

摘要/Abstract

摘要： 非酒精性脂肪肝和非酒精性脂肪性肝炎是当今社会的常见健康问题,且患病数量不断增加。本病预后不良,这就需要有一些可靠的诊断方法来进行评价。业内专家也需要对正在临床上应用的非侵入性、较为准确的诊断方法达成共识。本文对目前在临床上用于评价肝脂肪变性和肝纤维化的影像学方法进行了综述。有几种不同的影像技术用于评价脂肪肝病,如CT的密度分析、常规超声检查、磁共振波谱、磁共振质子密度脂肪剪影及可控衰减参数。肝纤维化阶段可由磁共振弹性成像及基于超声技术的瞬时弹性成像、剪切波弹性成像和声辐射力脉冲技术进行评价。虽然上述技术相对于肝活检来说只是可供参考的标准,但其准确度也较好,磁共振波普分析和磁共振质子密度脂肪剪影技术对脂肪变性的评价优于其他技术,磁共振弹性成像对纤维化的评价最佳。
