Accurate characterisation of bone metastases and their response to treatment remains an unmet need in oncology. Magnetic resonance fingerprinting (MRF) is an imaging technique that yields inherently co-registered quantitative images from a single acquisition, so this work aims to evaluate measurement repeatability of MRF when measuring T1 and T2 relaxation times in metastatic bone disease. We found good measurement repeatability of 6% for lesion mean T1 and 23% for lesion mean T2.
