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.

Abstract
Amaç: Blooming, gebelik sırasında küçük veya yavaş akan kan damarlarının değerlendirilmesi için önemli bir renkli Doppler artefaktıdır. Çiçeklenme derecesi kullanılan renkli Doppler tekniğine göre değişir. Çalışmamızın amacı, küçük damarların gerçek boyutuna en yakın görüntüleme yönteminin seçilebilmesi için çiçeklenme artefaktı ile ilgili doppler tekniklerini karşılaştırmaktır.
Yöntem: Bu çalışmaya toplam 100 gebe dahil edildi. İntrahepatik göbek damarının çapı, üç farklı renkli Doppler tekniği kullanılarak ölçüldü: geleneksel renkli Doppler (CCD), güçlü Doppler (PWD) ve ileri dinamik akış (ADF). Blooming, damar çapının B modunda ve renkli Doppler modunda karşılaştırılmasıyla değerlendirildi.
Bulgular: ADF ile ölçülen intrahepatik umbilikal venin çapı, CCD ve PWD ile ölçülenden daha küçüktü, bu da daha az çiçeklenmeyi gösteriyor. Çaptaki fark istatistiksel olarak anlamlıydı (p < 0.05).
Sonuç: ADF, CCD ve PWD'ye kıyasla daha az çiçeklenme ile sonuçlandığı için gebelik sırasında venöz akışta çiçeklenmenin değerlendirilmesi için üstün bir renkli Doppler tekniğidir. Bu bulgunun hamilelik sırasında küçük veya yavaş akan kan damarlarının doğru değerlendirilmesi için önemli etkileri vardır.
