Introduction
The four-dimensional color ultrasound primarily observes the fetal brain structure through imaging. If obvious structural abnormalities such as ventricular dilation or poor brain parenchyma development are present, these abnormalities may increase the risk of cerebral palsy and can provide reference for further evaluation. However, they cannot be used alone to diagnose cerebral palsy, although certain brain structural abnormalities that might lead to cerebral palsy could potentially be identified.
Under normal circumstances, a 4D color ultrasound cannot directly detect cerebral palsy, but it may identify certain structural brain abnormalities that could potentially lead to cerebral palsy. If any abnormalities are found, timely medical consultation is recommended. Detailed analysis is as follows:
A 4D color ultrasound primarily observes the fetal brain structure through imaging. If obvious structural abnormalities such as ventricular dilation or poor development of the brain parenchyma are present, these may increase the risk of cerebral palsy and can provide reference for further evaluation, although cerebral palsy cannot be definitively diagnosed based on these findings alone.
The causes of cerebral palsy are complex, with some cases resulting from factors such as hypoxia or infection before or after birth. During the fetal period, if no obvious brain abnormalities are present, a 4D color ultrasound may not detect these risks and therefore cannot determine whether cerebral palsy will develop.
Pregnant women should undergo all recommended prenatal examinations. If abnormalities are detected during a 4D color ultrasound, further diagnostic tests are necessary. After birth, close monitoring of the infant's developmental progress should be conducted to identify and address any abnormalities as early as possible.
