WebSep 21, 2024 · Diffusion MR imaging (DWI) is a widely available non-invasive non-contrast functional MR imaging technique with short acquisition time. It helps in the analysis of tissue characteristics based on the diffusion of water protons within the tissue. Quantitative assessment of a mass is possible by calculating its apparent diffusion coefficient (ADC) …WebAug 27, 2016 · Glucose is transported into the cell across the plasma membrane by facilitated diffusion, mediated by members of the glucose transporter (Glut) protein family (Glut1–6) [ 7 ]. Similar to glucose, FDG is also transported into normal and malignant cells by facilitated diffusion. 3.2.5.2.2 Hepatobiliary Agents
