Introduction
In early pregnancy, the size and development of the fetus can be assessed by two-dimensional ultrasound. At 9 weeks of gestation, a fetal pole length between 16-30 mm is generally considered normal. Therefore, if the fetal pole measures 22 mm at 9 weeks' gestation, this is typically within the normal range and indicates that the embryo is developing normally.
At 9 weeks of gestation, a fetal bud measuring 22 mm is generally normal. However, if there is no detectable fetal heartbeat or if the pregnant woman experiences abnormal symptoms, this may indicate an issue. The specific analysis is as follows:
In early pregnancy, the size and development of the fetus can be assessed via two-dimensional ultrasound. At 9 weeks gestation, a fetal bud length between 16–30 mm is typically considered normal. Therefore, a measurement of 22 mm at this stage usually falls within the normal range, indicating that the embryo is developing appropriately.
If the fetal bud measures 22 mm at 9 weeks but no fetal heartbeat is detected, this may be abnormal. By 9 weeks of gestation, a fetal heartbeat should typically be clearly visible. In such cases, the absence of cardiac activity could suggest embryonic demise and requires further evaluation. Additionally, if the pregnant woman experiences symptoms such as abdominal pain or vaginal bleeding, or if the doctor identifies other abnormalities during prenatal examination, these factors may also affect the assessment of whether a 22 mm fetal bud is normal.
It is recommended to undergo appropriate prenatal screening and regular hospital check-ups to monitor the health and development of both the embryo and the mother.
