Radiology education : the scholarship of teaching and learning The rapid pace at which knowledge is expanding and technological innovations are emerging presents both challenges and opportunities in imaging sciences. As workload and training demands increase the ways in which we practice and train future practitioners must evolve to meet the new demands.
