Imaging techniques for detecting pituitary adenomas

Thin-Slice Dynamic Contrast-Enhanced Imaging = Evaluates the vascularity and blood flow of pituitary lesions over time Fat-Suppressed Imaging = Helps differentiate between fat and non-fat components within pituitary lesions 3D Volumetric Imaging = Provides a three-dimensional view of the pituitary gland for precise localization and assessment of lesions Diffusion-Weighted Imaging (DWI) = May help in characterizing pituitary lesions based on their cellularity and diffusion properties

Slice thickness: 1-2 mm = Thin-Slice Dynamic Contrast-Enhanced Imaging Slice thickness: 3-5 mm = Fat-Suppressed Imaging High-resolution isotropic imaging = 3D Volumetric Imaging b-values: Typically 0 and 1000 sec/mm2 = Diffusion-Weighted Imaging (DWI)

Gadolinium-based contrast agent = Thin-Slice Dynamic Contrast-Enhanced Imaging No specific contrast agent mentioned = Diffusion-Weighted Imaging (DWI)
