Pituitary gland volume on magnetic resonance imaging: normative observations.
Pak J Neurological Sci Jan ;2(3):141-4.

Objective: The purpose of this study was to determine the normal range of pituitary gland volume in Pakistani individuals aged 30 or younger. Methods: A total of 220 subjects aged £ 30 years with normal pituitary morphology were evaluated by using T2 weighted Magnetic Resonance (MR) Imaging. Pituitary height (PH), width (PW), and length (PL) were observed. Pituitary volume (PV) was calculated using the formula for volume of an ellipsoid. Data were classified by gender and stratified into three age groups. Results: PV increased gradually to a peak in the second decade of life in females (316 ± 126 mm3, n = 43) and in the third decade of life in males (309 ± 117 mm3, n = 41). Significant difference was observed in PV within the different age groups in both genders. Conclusion: This study determines the measurements of normal pituitary volume in a selected population of Pakistan. These values are comparable with those obtained in other countries.
