What fetal areas can be examined with三级四维彩超 (three-level four-dimensional color ultrasound)?

Generally, a Level 3 four-dimensional color ultrasound can examine the fetal head, face, spine, heart, limbs, and other areas. Specific details are as follows:

1. Head: A four-dimensional color ultrasound can assess the integrity of the fetal skull and detect abnormalities such as skull defects. It measures indicators like biparietal diameter and head circumference to evaluate whether the fetal head size corresponds with the gestational age.

2. Face: A four-dimensional color ultrasound can examine the fetal eye sockets and eyeballs, assessing whether the size of the eyeballs is normal and detecting absence or underdevelopment of the eyeballs. It checks the fetal nasal bones for presence and normal shape, as nasal bone abnormalities may be associated with certain chromosomal disorders.

3. Spine: A four-dimensional color ultrasound can observe the continuity of the spine, detect developmental spinal deformities such as spina bifida, clearly visualize the alignment of the spine, and identify any abnormalities such as scoliosis or missing vertebrae. It also checks whether the physiological curvature of the spine is normal and evaluates the overall shape and development of the spine.

4. Heart: A four-dimensional color ultrasound can observe the position, size, and shape of the heart, determining whether the heart is located normally within the chest cavity, whether its size matches the gestational age, and whether its shape is regular. It evaluates whether the size proportions of each cardiac chamber are normal and whether the ventricular septum and atrial septum are continuous and intact, detecting any defects or abnormalities.

5. Limbs: A four-dimensional color ultrasound can assess the skeletal development of the fetal limbs, measuring the length of long bones such as the femur and humerus, evaluating whether limb development corresponds with the gestational age, and detecting abnormalities such as limb shortening or poor bone development.

Level 3 four-dimensional color ultrasound is a comprehensive and detailed prenatal examination method that provides important fetal health information for pregnant women and physicians. Pregnant women are advised to undergo this examination under a physician's guidance to assess fetal health status.
