We aimed to provide percentiles of intrauterine placental growth and relative fetal (placental ratio) by measuring volumes magnetic resonance imaging (MRI). In this prospective study, 107 unselected singleton pregnancies were examined MRI at gestational week 27 37. Based on the estimated placenta fetus, we calculated median weeks Median volume was 513 cm3 (Inter Quartile Range (IQR) 182 cm3), 831 (IQR 252 cm3) The 10th – 90th included between 392 717 27, 631–1087 ratio significantly higher than 37, with a 0.54 0.18) 0.31 0.08), respectively (p < 0.001). 10th-90th ratios 0.43 0.73 0.25–0.39 At about half size volume, whereas one third volume. This finding suggests that less prominent after 27. Knowledge distribution in general population are prerequisites for diagnosing abnormal size.
