Abstract The recent combination of positron emission tomography (PET) and magnetic resonance (MR) imaging modalities in one clinical diagnostic tool represents a scientific advancement with high potential impact in geoscientific research; by enabling simultaneous and explicit quantification of up to three distinct fluids in the same porous system. Decoupled information from PET-MR imaging was used here, for the first time, to quantify spatial and temporal porous media fluid flow. Three-dimensional fluid distribution was quantified simultaneously and independently by each imaging modality, and fluid phases were correlated with high reproducibility between modalities and repetitive fluid injections.

为地球科学解锁多模态 PET-MR 协同效应

摘要 最近在一个临床诊断工具中结合了正电子发射断层扫描 (PET) 和磁共振 (MR) 成像模式，代表了对地球科学研究具有巨大潜在影响的科学进步；通过实现对同一多孔系统中多达三种不同流体的同时和显式量化。此处首次使用来自 PET-MR 成像的解耦信息来量化空间和时间多孔介质流体流动。三维流体分布由每种成像模式同时独立量化，流体相与模式和重复流体注射之间的高再现性相关。
