The value of three-dimensional CT-scanning in head pathology.

The A. A. present five patients with intracerebral pathology in which three-dimensional CT-scanning has been performed. The coordinates and the range of volume of the processes can be given by this technique allowing for accurate surgical and/or radiotherapy management. Sagittal reconstructions add to completeness of spatial imaging of the relationship of the tumours to topographic landmarks. Holographic imaging can be derived from both axial and coronal cuts as well as from reconstruction modes. The A. A. indicate the fields of application of three-dimensional modes and maintain that three-dimensional isoattenuation coefficient curves could be very helpful for optimal radiotherapy treatment planning. Further, CT-scanning is a non-invasive way of assessment of the patients during treatment, after treatment and longterm follow-up.
