Brief Summary
The purpose of this study is to determine in a preliminary manner whether successful therapy of hot flashes can be associated with changes in the serotonin transporter in the brain. The serotonin transporter is important in delivering serotonin into certain portions of the brains (serotonin is a chemical that is important in the control of body temperature, mood, sleep, and other functions).

Outcome Measures
Primary Outcomes (3)
To estimate the proportion of women who have a 50% or greater reduction in frequency of hot flashes following 4 weeks of paroxetine or conjugated equine estrogen.
Following 4 weeks of study medication
To evaluate baseline and change in binding of the serotonin transporter in postmenopausal women who suffer hot flashes before and after 4 weeks of paroxetine or conjugated equine estrogen using PET.
Following 4 weeks of study medication
To correlate baseline and change in binding of the serotonin transporter using PET with reduction of hot flashes after 4 weeks of conjugated equine estrogen or paroxetine.
Following 4 weeks of study medication
