what does DR on a baby ultrasound mean?

DR on a baby ultrasound typically stands for "Ductus ArteriOSus," which is a blood vessel in a developing fetus that connects the pulmonary artery to the aorta. It is important for fetal circulation, allowing blood to bypass the non-functioning lungs. In some contexts, DR may refer to "Doppler Resistance," which assesses blood flow in fetal vessels. Always consult a healthcare professional for specific interpretations related to ultrasound findings.
