Summary A technique of radio‐active isotope placental localization using 113m lndium and a portable scintillation detector is described. It gave reliable results in 80 per cent of patients. The results were equivocal in 20 per cent. There were two false positive, but no false negative results. Doppler ultrasound was compared but gave unsatisfactory results in that a false negative rate of 28·5 per cent was obtained for placenta praevia.
