For diagnosing small pituitary gland lesions, a high spatial resolution is necessary. Due to its superior soft tissue contrast, MRI is the technique of choice for diagnosis of these lesions. Since a higher fieldstrength enables higher spatial resolutions, a dedicated pituitary gland protocol was developed at 7.0T, consisting of a T1-weighted Magnetization-Preparation Inversion Recovery TSE sequence and a T2-weighted TSE sequence, both with 0.8mm isotropic voxels. Highly detailed visualization of the pituitary gland was possible in 10 healthy volunteers and 2 patients, with high image quality and -contrast. This dedicated 7.0T protocol could have additional value in the clinical setting.
