Description
Estimated cost for 4D Fetal Ultrasound at general public hospitals in China is about ¥140-400, and at Grade 3A hospitals about ¥200-500, varying by hospital tier and region.
Main Uses
The 4D fetal ultrasound is used primarily for: 1. Detailed visualization of the fetus's face and body, 2. Assessing fetal growth and development, 3. Detecting potential congenital anomalies, 4. Monitoring amniotic fluid levels, 5. Evaluating placental position and condition. It is applicable in scenarios such as routine prenatal care, follow-up on suspected abnormalities, and providing a more realistic image of the baby for parents.
Normal Range
The 4D fetal ultrasound, or 4D prenatal ultrasound, does not have a numerical normal range as it is an imaging test. Instead, the normal findings include clear visualization of the fetus's anatomy, movement, and development without any structural abnormalities. Common indicators assessed are: fetal heart rate (110-160 bpm), amniotic fluid index (5-25 cm), and estimated fetal weight appropriate for gestational age.
Low Values - Possible Causes
Since 4D ultrasound is primarily qualitative, 'low values' do not apply in the traditional sense. However, if certain measurements like the amniotic fluid index (AFI) are low, it could indicate oligohydramnios, which may be caused by: 1. Fetal kidney problems, 2. Ruptured membranes, 3. Placental insufficiency, 4. Post-term pregnancy, 5. Maternal dehydration.
High Values - Possible Causes
Similarly, 'high values' refer to conditions where measurements exceed the expected range. For example, a high AFI might suggest polyhydramnios, which can be due to: 1. Fetal anomalies, particularly those affecting swallowing, 2. Maternal diabetes, 3. Twin-to-twin transfusion syndrome, 4. Rh incompatibility, 5. Congenital infections.
