简介：
Overview
This study utilizes bioluminescent, X-ray, and positron-emission tomography/computed tomography imaging to investigate the effects of mTOR inhibition on bone marrow-engrafted myeloma tumors in a xenograft model. This approach enables non-invasive, multimodal analyses of therapeutic impacts on myeloma tumors in vivo.
