With the development of more targeted therapeutics to treat malignant bone disease has come the associated challenge of developing more clinically relevant pre-clinical models, and identifying new non-invasive techniques capable of assessing the tumour phenotype and treatment response. To this end, a novel mouse model of multiple myeloma, propagated by direct intraosseous injection of cells, has been investigated by quantitative MRI. Tumour growth was localised to the skeleton, and assessed using high-resolution T2-weighted and diffusion-weighted imaging. Response to Bortezomib and Tosedostat was also assessed. Bioluminescence imaging , weekly Igλ serum levels, histology and flow cytometry provided qualification of the MRI data.
