Abstract

In this chapter an overview is given of different modalities for dose optimization and reduction in cranial CT and CT of the Head and Neck region. For adult cranial CT, the role of the justification process and the implementation of the use of imaging guidelines are discussed. Possibilities for dose reduction by use of diagnostic reference levels (RDLs) and the introduction of recent dose reduction techniques, like tube current modulation and iterative reconstruction, are overviewed. A separate part is dedicated to dose reduction in cranial CT of children. In the Head and Neck region, the main topics are use of low dose CT of the sinuses in adults and children and the recent introduction of cone beam CT as a low-dose alternative for conventional CT.
