Can a 4D color ultrasound detect fetal hydrocephalus?

Generally, four-dimensional color Doppler ultrasound can detect fetal hydrocephalus, and if necessary, the procedure should be performed under a doctor's guidance. Detailed analysis is as follows:

Four-dimensional color Doppler ultrasound offers high-resolution imaging capabilities, generating three-dimensional images of the fetus and displaying the real-time dynamic movements of the fetus within the mother's womb. This high-resolution imaging clearly reveals the fetal brain structure, including subtle anatomical features such as the ventricles, cerebral sulci, and gyri. When hydrocephalus is present, the ventricles become enlarged and there may be an obstruction in the cerebrospinal fluid (CSF) circulation pathway. These changes can be clearly visualized using four-dimensional ultrasound imaging.

Furthermore, four-dimensional color Doppler ultrasound incorporates Doppler flow imaging technology, which can display the blood flow dynamics in the fetal brain, including blood flow velocity and direction. When fetal hydrocephalus occurs, the CSF circulation may be impaired, potentially leading to abnormal cerebral blood flow. Using Doppler flow imaging, doctors can observe these hemodynamic changes, thereby further confirming whether the fetus has hydrocephalus.

Pregnant women should undergo regular prenatal examinations, particularly four-dimensional ultrasound scans, as recommended by their doctors, to promptly detect abnormalities such as fetal hydrocephalus.
