Normal Doppler Reference Values of the Pericallosal Artery

2015

Purpose: To provide the normal reference values of the Doppler flow of the pericallosal artery in relation to gestational age from 18 to 41 weeks of gestation. Materials and Methods: The pericallosal artery (PCA) was studied in 466 normal pregnancies. The pulsed Doppler evaluation of the pericallosal artery was done in A3 and A4 segments, and records from PI, RI and Vmax were studied. Results: The resistance index of the pericallosal artery in A3 / A4 segments exhibits a plateau from 18 to 31 weeks of gestation. After 31 weeks, a marked decrease becomes apparent. The pulsatility index of the pericallosal artery in A3 / A4 segments shows a plateau until 36 weeks of gestation. During the fina…

Entwicklung eines Wachstumsmodells für fetale Kopf- und Rumpfmaße

1987

Head parameters BPD, FOD and HC and abdomen parameters ATD, APD and AC have been ascertained in a prospective cross-sectional study in 515 healthy single fetuses between 13 and 40 weeks of gestation by ultrasound. In all cases ultrasound velocity was 1540 m/sec. From these data, a growth model was achieved for each parameter and corresponding growth curves with 5%, 10%, 50%, 90% and 95% percentiles were established.
