There are lots of improvements that have taken place in ultrasound Pregnancy Scans during the recent past. During the early days of 2D scans, a doctor's order was necessary in order to get an ultrasound scan to be conducted. But things have changed over the years with the advent of the 3D and 4D scans being available in private clinics.

You never need a doctor's order to get a scan done now-a-days. You could walk into any private clinic and ask for a pregnancy scan, no matter whether it is an early pregnancy scan or a 20 week scan. The only thing you need to ensure is that your scan is conducted by a licensed sonographer.

When you get your scan done in a private clinic, not only you will be able to see your baby on the computer screen but also you will get a DVD on your scan. There will be pictures of your baby also.
