Direct coronal computed tomography with 1.5mm contiguous scanning was done in total 95 cases, who had o clinical evidence of pituitary and hypothalamic disease. The evaluation of pituitary height, width, upper surface contour and density was done and the pituitary stalk was also evaluated. RESULT : 1. Total 95 cases were 45 males and 50 females. 2. The average height of mormal pituitary gland was 5.72$pm$1.44mm in female and 5.37$pm$1.17mm in male. There was no significant difference of pituitary height between male and female. 3. The pituitary height was decreased according to the increased age both in male ad female except prepubertal age. 4. The group between 15-30 year old age showed significantly increased pituitary height comparingto the remained age group both in male and female. 5. The upper limit of mormal pituitary height in 95% confidence level was 7.95-0.011xage infemale and 7.4-0.013xage in male. 6. The upper surface contour of normal pituitary gland were convex in 14 cases, flat in 58 cases adn concave in 23 cases. There was a significant correlation between the height and upper surface contour of putuitary gland. 7. The average width of normal pituitary gland was 13.4$pm$1.74mm in female and 13.69$pm$2.3mm in male. There was o significant difference between those of female and male. 8. The focal low density of normal pituitary gland was noted in only 8.4% and its size was always below 3mm. 9. Te pituitary stalk can be seen in 94.7% by direct coronal CT scanning and it was located at the midline. 10. There were nosignificant difference in pituitary height and width accordig to the menopause or the marrige.
