Which is more expensive, four-dimensional or large displacement

The cost of 4D ultrasound and large screening examination is usually similar, and the specific price difference is mainly affected by factors such as hospital level, regional consumption level, and complexity of examination items. The cost of four-dimensional ultrasound generally ranges from a few hundred yuan to a thousand yuan, and the cost of large screening examination is also in a similar range.

Four dimensional color ultrasound is mainly used to observe dynamic images such as fetal facial expressions and limb movements, with real-time imaging advantages. Some high-end private hospitals may increase prices due to additional services. As a systematic fetal structural screening, the prenatal screening includes detailed evaluations of organs such as the heart, brain, and spine. Some tertiary hospitals may charge slightly higher fees due to equipment accuracy and doctor qualifications. The pricing difference between the two inspections is more reflected in the service content rather than the technical essence. Secondary hospitals in economically underdeveloped areas may keep the cost of two tests within a lower range, while specialized hospitals in first tier cities may increase their fees due to the use of higher end equipment or the inclusion of genetic analysis and other items. Some medical institutions may launch pregnancy testing package services, which may offer certain discounts when combining 4D ultrasound with large screening fees. Pregnancy examinations should prioritize the qualifications of medical institutions and the experience of doctors, and cost factors can be comprehensively considered in conjunction with medical insurance policies. It is recommended to complete a major screening examination at 20-24 weeks of pregnancy and a four-dimensional ultrasound at 26-30 weeks. The two examinations are complementary and cannot be replaced by each other. When choosing a hospital, you can consult in detail about the details of the examination items to avoid duplicate charging items. In some areas, maternity and child health hospitals can also provide public welfare prenatal screening services as an alternative plan.
