When you have a scan, it can be performed either internally or externally. Both kinds of scan work in the same way, using equipment that converts sound waves into pictures. In general, women have internal scans earlier in a pregnancy and external scans later on in a pregnancy. The reason for this is that in an internal scan the probe is closer to the uterus and can produce better quality images. This means an internal scan can detect a developing baby much earlier than an external scan, so an internal scan is often performed to detect a pregnancy in the very early stages. Abdominal scans are performed once the baby is large enough for abdominal scans to produce clear images. For instance, the Nuchal Translucency Scan, performed at 12 to 14 weeks , is an external scan. Typically, the only factor you need to worry about beforehand is whether your bladder is full or empty. For an external scan your bladder usually needs to be full.
