The value of paramagnetic contrast agent XXXX in the diagnosis of @entity977 .

@entity5 @entity7241 @entity4611 @entity977 @entity652 @entity2287 @entity12306
The purpose of this study was to assess the role of MR imaging and the paramagnetic contrast agent @entity2287 - @entity12306 ( @entity7241 ) in the diagnosis of @entity4611 . 44 macroadenomas were examined with MRI before and after intravenous application of @entity7241 . @entity7241 produced excellent enhancement of solid @entity652 . The best contrast between @entity652 and surrounding structures could be gained on post-Gd T1-weighted images. Post-Gd images were equivalent to pre-Gd images in the evaluation of supra- and infrasellar extensions of macroadenomas. Post-Gd images had advantages in the evaluation of cavernous sinus invasion by @entity652 . The difference in degree of contrast enhancement between @entity652 and cavernous sinus facilitated the exact evaluation of lateral extension by @entity652 in 18 cases. Almost equal degree of enhancement of both structures @entity5 -sinus contrast in 2 cases. In the other 24 cases the @entity5 filled the cavernous sinus completely. It is our opinion that @entity7241 can be used on a widespread basis because of its excellent capability to highlight and delineate @entity977 .
