To access all the information within a 48 bit image file, you need a good graphics card that can I/O 48 bit and then a monitor that can display 48 bit. Then if you want to print, you need a 48 bit printer. The vast majority of monitors and even printers these days are 24 bit (true colour), so unless you have huge plans for the scanned files into the future, scanning at 48 bit doesn't mean a better image on your monitor or in print, at this time. You can get 48 bit printers now. Having said that a lot of the newer monitors can support 32 bit colour, and yes you can buy 48 bit graphics cards for reasonable prices, but to see true 48 bit colour you need every step of the process to be able to support 48 bit colour.

So really it is your choice which you use, but do your research into the processing hardware you have and see if it can support 48 bit, first. Just cause you can scan at 48 bit, doesn't mean you have to, 24 bit is damn good quality. Most current digital cameras are between 12-16 bit
