Abstract
Aim: Blooming is an important color Doppler artifact for the assessment of small or slow-flow blood vessels during pregnancy. The degree of blooming varies depending on the color Doppler technique used. The purpose of our study is to compare doppler techniques related to the flowering artifact so that the imaging method closest to the actual size of small vessels can be selected. Method: A total of 100 pregnant women were included in this study. The diameter of the intrahepatic umbilical vein was measured using three different color Doppler techniques: conventional color Doppler (CCD), power Doppler (PWD), and advanced dynamic flow (ADF). Blooming was assessed by comparing the diameter of the vessel in B-mode and in color Doppler mode. Results: Results: The diameter of the intrahepatic umbilical vein measured by ADF was smaller than that measured by CCD and PWD, indicating less blooming. The difference in diameter was statistically significant (p < 0.05). Conclusion: ADF is a superior color Doppler technique for the assessment of blooming in venous flow during pregnancy, as it results in less blooming compared to CCD and PWD. This finding has important implications for the accurate assessment of small or slow-flow blood vessels during pregnancy.
