摘要
Fast data acquisition imaging technologies such as modern computed tomography (CT) allow contrast agents to be used as tracers and nuclear medicine methodology may be used to derive a variety of functional/physiological information from dynamic CT. This article describes the theoretical basis and some practical applications of this idea including the measurement of perfusion, capillary permeability, vascular volumes, renal function and tumour responses to therapy.
