Our Imaging Tests
Pediatric radiologists at Phoenix Children’s Fetal Imaging Center use a full range of imaging tests to diagnose problems in an unborn baby or a pregnant mother.
Depending on the possible condition, you may have one or more of the following imaging tests:
Fetal magnetic resonance imaging, or fetal MRI, uses magnets, radio waves and a computer to make 2D or 3D pictures of your unborn baby. MRIs do not use X-rays and have no known side effects for your or your baby. These painless tests penetrate past bones and fluids in the body to produce clear, detailed images.
Fetal MRIs are usually done in the second or third trimester, after 20 weeks of pregnancy. They can reveal conditions of the placenta, brain, nervous system, heart, bones and other areas.
MRI provides information to help your doctor diagnose your unborn child’s condition, predict how your delivery will proceed and determine therapies for your baby.
Ultrasound uses reflected sound waves to produce an image of your unborn baby, the placenta and the amniotic fluid around the baby. Fetal ultrasound is a safe way for imaging specialists to view your baby and check for problems. The Phoenix Children’s radiology team may use this technique along with fetal MRI, since these tests can provide additional information when used together.
Fetal CT Scans
Fetal computerized tomography (CT) scans use low-dose X-rays to produce extremely accurate, 3D images of the unborn baby’s skeleton. Radiologists at Phoenix Children’s use this technology to examine the baby’s bones in special circumstances when an ultrasound or MRI test would not provide enough information for a definitive diagnosis.
