Contrast media are widely used in multidetectorrow computed tomography (CT) to improve visualisation of the vascular system and renal tract and to increase lesion-to-tissue contrast. Nevertheless, for patients within the first 6 h of acute stroke, the diagnostic and prognostic ability of conventional CT remains poor. Similarly, despite conventional contrast-enhanced techniques, mass lesions on CT may remain hard to characterize as benign or malignant, both at diagnosis and following cancer therapy. Furthermore, visual assessment of tumor enhancement rarely provides useful prognostic information beyond conventional staging. This paper describes how functional CT techniques can maximize the benefits of administering contrast media and so improve the assessment of patients suffering acute stroke or cancer.
