The Sagittal MR inages of pltuitary gland were performed before and after smoking on thirteen volunteers
The Signal intensity ratio and area of high signal of posterior pituitary lobe in mid-sagittal MR images weremeasured. As a result
the highintense signal of posterior pituitary lobe was seen beforesmoking
After smoking
the signal intensity of posterior lobe was decreased in 9 cases(69.3%)
changed into iso-intensity signal atanteroinferior portion. The signal intensity and area of high signal of posterior pituitary lobe showed asignificant change(P< 0.001).
