A pharmacokinetic analysis of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) data is subject to inaccuracy and instability partly owing to the partial volume effect (PVE). We proposed a new multicompartment model for a tissue-specific pharmacokinetic analysis in DCE-MRI data to solve the PVE problem and to provide better kinetic parameter maps.

使用非负矩阵因子分解的DCE-MRI肿瘤内组织特异性分析的多室模型

动态对比增强磁共振成像(DCE-MRI)数据的药代动力学分析存在误差和不稳定性,部分原因是部分体积效应(PVE)。我们提出了一种新的多室模型,用于DCE-MRI数据中的组织特异性药代动力学分析,以解决PVE问题并提供更好的动力学参数图。
