Dynamic T1W contrast-enhanced sequence is considered to
be the gold standard to evaluate the pituitary gland.
However, it does not allow assessment of perfusion
characteristics of the pituitary gland. The purpose of
this study was to demonstrate the utility of recently
developed Radial-VIBE with GRASP to evaluate perfusion
characteristics of individual component of pituitary
gland. Signal-time curves generated from 79 patients
demonstrated significant differences in the enhancement
pattern and perfusion metrics between anterior,
posterior pituitary gland and median eminence. This
validation study confirms the ability of GRASP technique
to evaluate the hitherto unexplored perfusion
characteristics of the pituitary gland.
