IMAGING PHYSICS SEMINAR
National Institute of Standards and Technology
Quantitative MRI: from Bench to Bedside
Quantitative MRI: from Bench to Bedside Magnetic Resonance Imaging (MRI) is an exquisite tool for probing the anatomical structure of the human body. It is also capable of measuring physical parameters such as relaxation times, diffusion and temperature, known as quantitative imaging biomarkers (QIBs). When acquired using methods with known limits of bias and reproducibility, these QIBs allow for comparison of scan data across patients, imaging sites, and time, turning into a powerful tool for clinical trials and patient care to evaluate disease state and treatment response.
In this seminar, we will examine the state of QIBs, their future direction, and the key role physics plays in MRI, enabling precision measurements for precision medicine. We will discuss efforts to advance the utility of these QIBs through metrology and ground truth references, tools for optimizing MRI scans, and the importance of standardizing image acquisition protocols. Finally, we will consider a future for medical imaging that utilizes multiparametric evaluation of patients in combination with machine learning to enable new metrics and means of assessing patient health, disease detection, and treatment efficacy.
