Abstract:
PURPOSE: The purpose of this study is to evaluate the signal intensity and size of anterior pituitary gland in postpartum women, and to compare with those of control group. MATERIALS AND METHODS: In 34 postpartum women(18-43 years, mean:27 years) and another 35 control nonpregnant women(20-29 years, mean :24 years), midsagittal Tl-weighted MR images were obtained. The signal intensity and height of the anterior pituitary gland were compared between the post-partum and normal control groups. RESULTS: In postpartum women, the signal intensity of the anterior pituitary gland relative to the pons was higher than that of the control gorup. Pituitary gland height of postpartum women was higher(5-11. 8mm, mean:8.18 +/- 1.8mm) than that of control group(2-9mm, mean :6.2 +/- 1.7mm). CONCLUSION: It is concluded that the hyperintensity of the anterior pituitary gland on Tl-weighted image is a normal finding in postpartum women, which is useful in differentiation from pituitary abnormality.
