Quantitative imaging can detect subtle changes invisible to the naked eye and enables establishing healthy normative ranges. We report a comprehensive pipeline for fully automated assessment of the lumbar intervertebral disk based on a single fast T2-mapping acquisition of 2:27 min. In this proof-of-concept study, norm values are derived from 19 healthy subjects. Feasibility is shown in 19 patients: three regions are automatically segmented in each intervertebral disk and compared to corresponding norm values. Results are then compiled in a report where abnormal regions are flagged.
