Placenta scintigraphy using markers of the uterine cervix and pelvic skeleton

A method of placenta scintigraphy is described which provides a differential diagnosis between total and marginal placenta praevia. The uterine cervix, symphysis and 5th lumbar vertebra are included on the scintigram by means of atraumatic markers. Of 101 examined patients 6 had total placenta praevia and 12 marginal placenta praevia. No incorrect evaluation of the scans or complications occurred. The examination supplements ultrasound scanning in late pregnancy. (Auth.)
