Abstract

The brain MRI of 215 patients referred to our department without signs and symptoms relating to pituitary gland were studied. In each case, two to three images of the mid-sagittal region from routine brain protocol of the sagittal Twi were selected to determine the posterior bright spot of the pituitary glands. The age distribution of the patients which had been studied, were as followed: 0-12 years; 73, 12-20 years; 17, and more than 20 years; 155 respectively. The incidence of the posterior bright spot, we found were 39 in 73 of the 0-12 years age group, 15 in 17 of the 12-20 years age group and 122 in 155 of the group aged more than 20 years. No significant differences in the detection rates of the posterior bright spot in different age groups (x2= 0.05). The total detection rate of the bright spot for the total study of 215 patients is 82%
