Abstract

Pituitary size can vary between normal subjects depending upon age, sex and other conditions. It is important to know the range of normal size to enable radiologists to suggest what might be an abnormal pituitary gland. Previous studies into the size and shape of the normal pituitary gland have previously been performed in the 1980’s during the dawn of the magnetic resonance imaging (MRI) with old technology, but not on any 3-dimensional sequence using isometric voxels. This study aims to produce accurate data for the dimensions of the normal pituitary gland in 101 patients and is first study using 3D FLAIR sequence. Our results show a mean pituitary gland height for males of 5.52±0.73mm and 5.66±0.96 for females which is consistent with previous similar studies performed internationally. Our data also postulates the relationship between the different dimensions of the pituitary gland in relation to the age of the patient with regards to the height, width and depth of the gland. We have also highlighted the need for a standard for accurate measurement of the pituitary gland size and further studies into the volumetric changes in relation to age.
