title: Placental aging monitored by gray scale echography.
abstract: With gray scale ultrasonics echography, it is possible to identify changes in placental anatomy which formerly have been recognized only by examination of the placenta after delivery. By serial examinations these changes can be detected as they occur. The significance of the changes is discussed and an association between the premature appearance of aging of the placenta and a decline in placental function is noted.
