The placenta was localized in 99 women, between the 35th and 40th week of pregnancy, by both the Doppler flowmeter and the gamma camera, using 300 μCi 99 m Tc as the tracer. The conclusion from each method was the same in 84 cases (85%) and different in 15 cases. In only 4 of these latter cases was the placenta located in opposite quadrants of the uterus by the two methods. According to the results obtained, use of the Doppler flowmeter is a suitable screening test.
