Synopsis

Keywords: Image acquisition: Quantification

This lecture will provide an overview of the latest advances in MRI techniques that enable quantification of tissue properties. Specific topics that will be covered include approaches for fast quantitative imaging and techniques that aim at improving the accuracy of QMRI. Remaining challenges in quantitative MRI will be briefly discussed as well as potential new research directions.

MRI is incredibly versatile due to its sensitivity to a large number of tissue properties and processes. The range of properties that have been assessed with MRI includes NMR relaxation times T1, T2, T2*, diffusion, perfusion, quantitative fat fraction, iron fraction, elastic properties of tissue, temperature, chemical exchange, to name a few. While this opens the opportunity for comprehensive tissue characterization, this sensitivity also presents a challenge to robust quantitative MRI. Even though attempts to measure quantitative parameter maps (relaxation properties and diffusion) date back to the very early history of MRI, today, still most of the MRI images are qualitative in nature and contrast is used to derive the needed clinical information. However, more and more quantitative MRI techniques are being developed and increasingly adopted clinically.
