The purpose of this scan is to see if the baby appears normal. While major abnormalities will show up on scan, some problems may not be picked up.

The Sonographer who performs the scan will explain to you what will happen during the examination, and once it is completed she or he will show you your baby in as much detail as possible.

Every pregnant woman wants to know her due date. But a due date calculated from last menstrual period with a due date calculator often doesn’t match the due date that is estimated by ultrasound also known as a sonogram. During an ultrasound, a technician spreads a warm gel over the lower part of the abdomen, and then presses a tool called a transducer against the belly to examine the fetus using sound waves.
An image of the fetus appears on an accompanying computer screen. While looking at this image, the technician takes some standard measurements from different angles and listens for a heartbeat. Sonograms are risk-free, and seeing your baby will likely be an enjoyable experience.
