How many weeks pregnant can I do four-dimensional

20-24 weeks of pregnancy can do four-dimensional.

20-24 weeks of pregnancy, fetal organ development is relatively perfect, can clearly show the structure of each organ, so that doctors can carry out a comprehensive examination and evaluation, timely detection of possible abnormalities or abnormalities. At this time relatively more amniotic fluid, fetal movement in the amniotic fluid is more free, convenient for doctors to observe the fetal shape and movement from different angles, so as to obtain more accurate and detailed information.

In addition, too early for four-dimensional examination, some fetal organs may not be fully mature, may occur missed diagnosis or misdiagnosis; and too late, it may be due to factors such as fetal size, reduced activity space, affecting the accuracy and comprehensiveness of the examination.
