ABSTRACT
Computed tomography (CT) involves the use of X-rays to image thin sections of the body.
Advances in clinical CT in recent years including new tube and detector technology and dual-source and multispectral CT have pushed the boundaries for CT imaging and allowed so-called ‘functional’ applications in addition to high resolution anatomical imaging. This chapter will discuss perfusion CT, dual-energy and multispectral CT, and emerging techniques including photon counting CT for oncological applications.
