Pregnant Obese Women and Fetal Ultrasound Quality.

Echography in Pregnant Obese Women and Ultrasound Speed.

Source: ClinicalTrials.gov · Last updated 3 Jan 2025

Brief summary (registry, in English)

Ultrasound (US) image construction uses equations that contain the value of the propagation velocity of sound waves; this velocity is assumed conventionally to be constant and equal to 1540 m/s in the human body. Since 1977, all manufacturers of US scanners have used this value, which was first established in 1950. In fatty tissue, however, the actual propagation velocity is only in the order of 1450 m/s. US velocity in fat tissue is slower than in other soft tissues (ie:1450 m/s vs 1540 m/s) therefore the intrinsic image quality in terms of sharpness and precision is improved when considering this parameter for image construction The main objective of this study is to evaluate the impact of ultrasound propagation velocity setting on completeness of ultrasound exams and images quality during the second and third trimester fetal ultrasound examination in obese patients.
