The 3D ultrasound pictures may also help the family appreciate to what extent the baby is affected. ![]() These new modalities of ultrasound can help by clarifying the abnormalities. 3D/4D ultrasound is increasingly important when fetal abnormalities are suspected or picked up. This main scan is also known as the 18 to 20 week Ultrasound, Anatomy Scan, Morphology Scan, and Mid-Trimester Ultrasound. Most women also find it pleasurable watching the 3D/4D pictures of their babies. The addition of 3D and/ or 4D scan is a bonus and may enhance the bonding between the family and the unborn child. What are the roles of 3D/4D ultrasound in assessing the fetal structures?įor a routine assessment of the fetal morphology, 2D ultrasound is already adequate. ![]() ![]() The pick-up rate depends on a number of factors, including the severity and nature of the abnormality, whether the fetal position is optimal for scanning, women’s factors such as whether the tummy is thick or there is surgical scar, the quality of the ultrasound machine and whether the medical personnel are experienced in or have received adequate training in this practice. Not all congenital defects can be picked up on a fetal morphology scan. What are the limitations of morphology scan? Also, if it is scheduled after 24 weeks of gestation, termination of pregnancy is not permitted by law in Hong Kong even a major fetal defect is discovered. Assessment of the fetal structures might also be difficult at late gestation such as after 37 weeks because the fetal bony structures are mature, causing acoustic shadow on the internal organs. However, assessment of some complex structures such as the fetal heart might be difficult at early gestation. With the advance of ultrasound machines, many congenital anomalies can be picked up between 11-14 weeks of gestation. Fetal structures can also be assessed earlier than 18 weeks if indicated. At this gestation, there are usually good views of the fetal parts and internal organs. When is the best timing for fetal morphology scan?Ī fetal morphology scan is usually performed during 18-22 weeks of gestation. Structures that are commonly assessed during a morphology scan include: cranium, intracranial structure, orbits, lips, spine, heart, lung, diaphragm, stomach, kidneys, bladder, other structures within the fetal tummy, umbilical cord, limbs and fetal genital organ. ![]() In addition, the fetal structures are carefully assessed. This is a good time to examine the babys morphology, at this time, the fetus is. For a fetal morphology scan, the above parameters are checked. My First Baby Pictures 3D/4D Ultrasound is a mobile business that comes to you in the comfort of your own home. Second: 20 weeks pregnant 4d ultrasound or 22 weeks pregnant 4d ultrasound. How is this morphology scan different from the ordinary antenatal ultrasound?ĭuring an ordinary antenatal ultrasound, the fetal heart pulsation, fetal size and presentation, amniotic fluid volume around the fetus and the placental site are usually assessed. For certain major congenital defects, the parents might have the option of terminating the pregnancy. By knowing the abnormalities, prenatal diagnosis might be possible and the parents, the obstetricians and the paediatricians might be better prepared for the birth of such affected child. In case a baby has some structural defects, it might be important to find out before he or she is born. Most babies are normal and the parents can be reassured with the normal ultrasound findings. A fetal morphology scan aims to carry out a thorough check of the structures of the fetus. While not every pregnancy will include a 16-week ultrasound, at some point between the 16- and 20-week gestation period, you’ll likely complete this important step.
