    Abstract:
    When planning treatment of tumours in the sella region it is of the utmost importance to obtain precise information about the localization, spread, and (if possible) the type of alteration. Aside from the classic radiographic methods of native diagnosis, angiography, and CT, MRI has been available for some years now. This is a method whereby images can be gained from the various stages of an energetic reaction in the biological substrate: tomograms are possible for any desired plane--those routinely needed for cerebral diagnosis from the horizontal, coronary, and sagittal planes and, given a further improvement of this technology, from special oblique planes which can be matched to the direction of a probable surgical approach. A number of examples demonstrate the significance of this new method, which is a valuable addition to the procedures used up to now: indeed, in some cases it is superior to them. It has been shown that most of the neighbouring structures which border on or have been pushed aside by the tumour in the sella region (blood vessels, brain, optic chiasma, subarachnoid spaces, and occasionally even bone structures) can be identified better than with the procedures used up to now. MRI has thus proved to be valuable, and occasionally indispensable, for the correct choice when considering the many therapeutic methods available for tumours in the sella region.
