Actually, I unfortunately know a fair bit about medical imaging (since I supported radiology systems for a couple years).
There's a ~1980s protocol called DICOM which is largely used to transport images around. It is quite complex for what it actually, has lots of vendor and device inconsistencies, and because medical imaging devices are expensive and have a long duty cycle, you can have a 10-20 year spread of equipment on your network.
Some of the actual imaging technologies (MRI, CT, US) are inherently low resolution per image in a study (due to the limits of physics), but a study can be composed of a bunch of images, and it can end up 5-10GB. The high-resolution individual images tend to be x-ray, especially digital mammography.
