OVERVIEW:
Standardisation is vital and underpins all aspects of modern society. Standard measures of time underpin GPS, standard measures of mass underpin the whole economy, even abstract principles such as “quality” are governed by standards, e.g. ISO 9001. Medical physics is no exception, and we see international standardisation work in modalities such as radiotherapy and CT. Concerningly, amidst the backdrop of our standardised world, MRI is not officially classed as a quantitative method in the international standards landscape, but instead as “exempt” and “Not a Measurement Device.”
Following on from the high level of interest seen in ISMRM 2023, this session highlights and explores some of the key areas that are vital for the development of standardised techniques in MRI. In all other areas of measurement, metrology provides the foundation relating any given measurement to the internationally agreed SI unit system. In quantitative MRI, we are interested in clinical biomarkers that tell us what to measure and what is happening inside a patient. Repeatable, replicable, and robust measurements require both the biomarker and the measurement process to be understood and well-characterised.
We will learn how we can be sure that a second is a second. We will learn where standardisation is needed the most, and we will learn how we can get the measurements we need, in a consistent way. Most importantly, we will discuss how the global ISMRM community can work together to solve this issue.
TARGET AUDIENCE:
Clinical researchers, radiographers, manufacturers, clinical scientists, and any scientist interested in any form of quantification using MRI.
AS A RESULT OF ATTENDING THIS COURSE, PARTICIPANTS SHOULD BE ABLE TO:
- Gain an understanding of the role of metrology in underpinning measurement processes, and how this can support in MRI; and
- Focus on the most important areas where standardised measurements could aid in patient care, and in the development of new therapies.
