Purpose: We have attempted to evaluate the reliability of a new volumetric technique for MR imaging applied on measurements of phantoms with defined volumes and the normal pituitary gland (PG) of healthy individuals. Methods: In nine males without a clinical history of pituitary abnormalities and in a phantom study we performed triplicate MRI measurements before and after repositioning for volumetry of the PG or the phantoms, respectively. Using a standard head coil on a 1.5 T scanner, a tilted sagittal T1w 3D magnetization-prepared rapid gradient-echo sequence was applied with TR/TE/alpha=15/5ms/30, 256×256 mat…
