Among the multiple examinations performed during pregnancy, ultrasound examination is the most common. However, the purpose of ultrasound examination varies at different stages of pregnancy, and pregnant women also need to have a preliminary understanding of prenatal ultrasound examination. So, what does pregnant woman ultrasound fw mean?
1. During pregnancy, women need to undergo multiple ultrasound examinations, and some expectant mothers may find the English letter fw on the ultrasound sheet, which expresses the description of a certain result after ultrasound examination, referring to the estimated weight of the fetus. Moreover, with different gestational weeks, ultrasound examination may indicate different fetal weight results.
2. During pregnancy, there are often many English abbreviations on the ultrasound examination form for women, indicating a certain test result data. For example, BDP indicates the length between the fetal biparietal diameter and the head on both sides, also known as the head transverse diameter. When measuring the estimated fetal weight, it is also necessary to combine this data to calculate the measurement result of fw.
3. Pregnant women often have crl indicating the head to hip meridian and S/D indicating the ratio of fetal umbilical artery systolic and diastolic pressure on their ultrasound scans. If there is abnormal placental or umbilical cord function, this ratio will show abnormal changes. Hc also represents fetal head circumference, while fl chart indicates fetal femur length, and these are common English abbreviations on pregnant women's ultrasound scans.
