The Value of High-field MRI (3 Tesla) in the Assessment of Sellar Lesions

Purpose: The aim of this study was the evaluation of the normal sellar anatomy in-vitro and in-vivo with high-field MRI and its application in the diagnosis of sellar pathologies in comparison to standard MRI. Methods: All high-field MR images were obtained using a 3 Tesla Bruker Medspec 30/80 Scanner with a head birdcage transmit/receive coil and an actively shielded gradient system with a maximum gradient strength of 45mT/m. Firstly an in-vitro study of the sella turcica was performed to depict normal pituitary and sellar anatomy at high fields.After a pilot-study this sequence-protocol was established:For T2-…
