Four-dimensional ultrasound suggests that there are localized bowel echoes slightly enhanced, there is no specificity, the vast majority is normal, but should be careful to exclude accompanying other abnormalities.
Fetal intestinal echogenic enhancement is not specific, the enhanced echoes are diffuse or focal, and may be similar to the echoes of the surrounding bones. Localized echogenic enhancement is classified as grade 0, grade 1, grade 2, and grade 3, of which grades 0 and 1 are mostly normal and basically do not have any other abnormalities, whereas grades 2 and 3 have the possibility of being accompanied by other abnormalities.
According to clinical data, it is normal for most fetuses to have slightly enhanced localized intestinal echogenicity, but if it is accompanied by other abnormalities, chromosomal abnormality of the fetus should be excluded.
Nuchal fold thickening, ventricular punctate echogenicity, and bowel echogenicity are common ultrasound soft indicators, which are not fetal structural abnormalities per se, and are related to fetal chromosomal abnormalities, but most of them are normal, and should be consulted at obstetric clinic if abnormalities are detected in the labor examination.
