In terms of taking a digital mammogram, it's no different. It's the same thing.  You come in, they put the glass down on both directions. They flatten you one way and then they flatten you the other. The difference comes in the radiologist's ability to look at the mammogram. It's available immediately.  And they have digitally, they have the capability of zooming in on a suspicious area and looking at it more closely. A normal mammogram X-ray looks just like a bone X-ray, if you've ever had one.  It is a static picture of something. And you have to squint and look at it and hold it up to the light and say is that a fracture?  Whereas with a digital mammogram right there on the computer screen when they are looking at it they can say "Gosh that looks suspicious. I want to have a closer look at that". And they can zoom right in and look at certain factors on it.
