[Comparative evaluation of conventinal and dynamic magnetic resonance imaging, of the pituitary microadenomas]

This study tried to determine if there is a difference between standard and dynamic MR examination in detection of pituitary microadenoma.

We have included twenty seven patients with suspicious pituitary tumor. All patients have been hospitalized for endocrinology examination between June 2007 and May 2008 in Institute for Endocrinology, diabetes and metabolic diseases of Clinical Center of Serbia. MR examinations have been preformed in MR Center of Clinical Center of Serbia.

Twenty seven patients were included in our study. Only in four of them pituitary microadenoma was detected using dynamic MR examination. One was somatotrophin secreting adenoma, and three were corticotrophin realizing adenomas. There were no statistically significant differences between conventional and dynamic MR examination.

Dynamic MR Examination as method can hardly match standard MR examination which remains standard in detection of pituitary microadenomas.
