What can be done by 4D ultrasound?
--Determining the age of the pregnancy
--Determining whether the uterus is growing faster or slower than expected and pinpointing the reasons why this might be occurring
--Examining the baby's physical development and functions such as breathing, heartbeat, excretion, and body movement
--Measuring amniotic fluid late in pregnancy
--Imaging the limbs and spinal column to check for proper formation and growth
--Imaging the development of the brain and other major organs
--Determining whether the pregnancy is ectopic (occurring in the fallopian tubes instead of the abdomen)
--Determining whether there is a multiple pregnancy (i.e., twins, triplets, quadruplets)
--Determining the due date of the pregnancy
--Confirming a possible miscarriage (warning signs may include bleeding early in pregnancy or cessation of fetal heartbeat and movement)
--Determining the cause of bleeding during the second or third trimester (causes may include problems with the placenta, which may require a cesarean delivery or special care)
--Diagnosing some birth defects, such as missing limbs, spina defida (a gap in the spine), or malformations of the urinary tract. A special type of ultrasound exam called echocardiography images the blood flow through fetal heart chambers and major blood vessels to help detect heart irregularities.
--Guiding other obstetric/prenatal tests, such as amniocentesis (sampling fluid from the womb) or the sampling of cells from the chorionic villus (vascular projection from the embryo that attaches the pregnancy sac to the uterine wall).
--Guiding prenatal surgery and the safe delivery of medications to the fetus
--Determining whether a cesarean delivery is needed (instances may include when the fetus is especially large or in an abnormal position, or when the placenta is blocking the exit from the uterus)
