Quantitative magnetic resonance imaging extends beyond qualitative MRI by combining both image graphics and mathematically measured intrinsic image features to determine tissue characteristics, development, pathology, etc. While MRI has practically been qualitative both in the imaging process and interpretation, quantitative image analysis involving the mapping of numerical tissue properties with nominal values obtained from healthy cohorts has proven to add extra information to MRI images.
In this educational review we discuss the rapidly evolving field of radiomics in quantitative MRI imaging. Particular emphasis is laid on development of radiomic models for MR image analysis, validation strategies and anticipated future trends.
