Computed tomography is an imaging test that uses X-rays and a computer to make detailed images of the body. A CT scan shows details of the bones, muscles, fat, and organs. CT scans are more detailed than standard X-rays.
This procedure may be used to diagnose back or neck pain, fractures or broken bones, arthritis, degeneration of the disks, tumors, or other problems.
Screening is usually performed by taking a sample of the mother’s blood between the 15th and 20th weeks of pregnancy (16th to 18th is ideal).
First trimester screening combines fetal ultrasound and blood tests for the mother. It’s done during the first trimester of pregnancy, during weeks 1 to 12 or 13. It can help find out the risk of the fetus having certain birth defects.
Because many multiples are small and born early, they may be initially cared for in a special care nursery called the neonatal intensive care unit (NICU).
Birth defects may be caused by inherited (genetic) problems or by environmental things, such as exposure to certain toxic substances during pregnancy. Some birth defects can be linked to a direct cause. Other reasons are not as clear.
