Abstract

Dynamic contrast-enhanced MRI of the pituitary gland was used in ten patients. It is interesting in our preliminary series because it could appreciate the contrast kinetics of the sellar, laterosellar and parasellar components as well as adenomas. In one case, it discovered a lesion. In another, it suspected cavernous sinus invasion. The dynamic contrast-enhanced sequence was equivalent to conventional sequences in the other four lesions in terms of diagnosis and extent. Subtraction of precontrast images and the use of lower-dose boluses could improve these techniques further.
