Contrast-Enhanced T2-Weighted STIR Imaging of Pituitary Adenomas

This technical report presents the application of a postcontrast T2-weighted STIR sequence for improved visualization of pituitary adenomas. Though STIR is traditionally employed to null the fat signal, it is typically avoided in postcontrast imaging due to the hypointense appearance of both fat and gadolinium-enhanced tissues. Our approach exploits this characteristic to render the normal enhancing pituitary gland hypointense, thereby allowing the adenoma to remain hyperintense and thus increasing its conspicuity.
