Radioactive oom Tc (300 μCi) tracer and a gamma camera were used to study placental function between the 34th and 40th weeks of pregnancy in 10 women with a normal pregnancy, 34 with mild and two with severe pre‐eclampsia. The placenta was first localised by the Doppler method and then the gamma camera was aimed at right angles to the site. After the injection the radioactivity over the placenta was counted and a series of radiographs was made at intervals of 30 sec for up to 12 min. The two values correlated. When the material was grouped according to the week of pregnancy, perfusion was fastest in the 34th week (3.1 ± 0.87 min) and slowest in the 40th week (5.5 ± 1.27 min). The difference was significant. There was no significant difference when the material was divided into groups on the basis of normal and toxaemic pregnancies.
