Magnetic resonance imaging (MRI) is the most flexible and powerful non-invasive diagnostic imaging technique available to clinical medicine. MRI as a largely qualitative tool is well established. As a non-invasive method, MRI is principally used to visualize the internal structure of biological systems through mapping the spatial position of hydrogen (water). The magnetic resonance signal lifetimes and molecular diffusion usually manifest qualitatively in the MR image contrast. Quantitative analysis of these parameters will reveal molecular scale information, since magnetic resonance is sensitive to a range of physical/chemical characteristics including molecular structure, motion, size and interactions, through the measurements of signal lifetime and molecular diffusion. The potential for quantitative MR has been recognized. However, significant methodological developments are still required for this potential to be fully realized.

磁共振成像（MRI）是最灵活和强大的非侵入性诊断成像技术可用于临床医学。MRI作为一种主要的定性工具已经得到了很好的确立。作为一种非侵入性方法，MRI主要用于通过绘制氢（水）的空间位置来可视化生物系统的内部结构。磁共振信号寿命和分子扩散通常在MR图像对比度中定性地表现出来。这些参数的定量分析将揭示分子尺度的信息，因为磁共振是敏感的一系列物理/化学特性，包括分子的结构，运动，大小和相互作用，通过测量信号寿命和分子扩散。定量MR的潜力已经得到认可。然而，要充分实现这一潜力，仍需在方法上取得重大进展。
