Abstract

Quantitative MRI has been an active area of research for decades and has produced a huge range of approaches with enormous potential for patient benefit. In many cases, however, there are challenges with reproducibility which has hampered clinical translation. Quantitative MRI is a form of measurement, and like any other form of measurement it requires a supporting metrological framework in order to be fully consistent and compatible with the international system of units. Such a framework is not yet complete, but a considerable amount of work has been done internationally to build one. This article describes the current state of the art for MRI metrology, including a detailed description of metrological principles and how they are relevant to fully quantitative MRI. It also undertakes a gap analysis of where we are versus where we need to be to support reproducibility in MRI. It focusses particularly on the role and activities of national measurement institutes across the globe, illustrating the genuinely international and collaborative nature of the field.
