title: [Magnetic resonance and computerized tomography in the study of hypophyseal adenomas. Comparative results].
abstract: Magnetic resonance evaluation of 28 cases of pituitary adenomas has shown remarkable accuracy. Compared with HR-CT, MR gives comparable results in tumour identification. MR better demonstrates the suprasellar extension of macroadenomas and their relationship to the visual pathway and is more effective in showing direct and indirect signs of microadenomas. HR-CT however better recognized bone abnormalities of the sella turcica, due to adenomas. A typical increased signal intensity has been demonstrated in most of the adenomas studied.
