[Application of spiral CT in the head and neck region].

In comparison with other regions of the body, spiral CT has only been recently applied in the radiological evaluation of the head and neck region. Some interesting applications seem to emerge. The fast data acquisition allows to examine children (e.g. temporal bone examinations) without sedation, to reduce patient moving artefacts in adults, and to limit the dose of injected contrast material in enhanced studies. Furthermore, without additional irradiation, images with a very small table increment can be calculated out of the volumetric data set, allowing generation of high quality secondary reconstructions.
