Many hospitals use a pneumatic tube system to get developed x-rays from the lab to where they are needed. An x-ray image can contain several 100's of gigabytes of data (hint: the developed image is 18 x 36 inches or larger). The P-Tube is much faster than hand-carrying the the film to the requesting physician.

Ten years ago we found out that we couldn't send the images over the brand-new state-of-the-art in-house network with any sort of reasonable delivery time (minutes, not hours), and not bring the network to its knees every five or six minutes. Since our central lab processed 50+ terabytes of x-ray data per day, and the P-Tube system has the necessary (slightly colossal) band-width to get an image to the Doctor/Trauma Surgeon before next Michaelmas, it was a win-win with Ancient Technology. Besides, the P-Tubes had been designed into the building (in the 50's) to support moving paper files around the complex, so we were just adding a couple of hundred more 'packets' per day.
