Abstract
MRI may be presently considered as the optimal imaging technique for the study of the sellar and parasellar region. Excellent anatomic and multiplanar approach, absence of irradiation, spontaneous visualization of vascular elements, absence of artefacts characterize MRI. The normal aspect of the sellar region is first described on both spin-echo, T1 and T2 weighted images. MRI appearance of micro and macroadenomas is described. The use of paramagnetic contrast agents (Gadolinium DTPA or DOTA) is widely accepted as a useful complementary diagnostic tool. Moreover the most commonly encountered lesions of the sellar region are reviewed and their behaviour on MRI discussed. Although MRI is an outstanding imaging technique, particularly useful for the study of the sellar region it must be stressed that MRI lacks of specificity. As a consequence, it is of utmost importance to compare MRI with clinical and biological examinations in order to reach a confident final diagnosis.
