It depends on what you will accept as "frameable." 300 dpi is an industry standard, but you would need over 39 MP for that. 200 dpi is often "acceptable," but you would still need over 17 MP for that. If you print at 167 dpi, you can get this out of 12 MP and if you print at 152, you can get this out of 10 MP. Do a test of a small section of any image at these resolutions and see how far away you have to be to make it look acceptable to you. You are not going to be viewing an 18x24 print from 15 inches away, so maybe the resolution would be okay for your purposes.

I agree with Dr. Sam. I've made prints this big with 8 and 10 MP cameras and the results were fine - but only because the viewing distance was over 2 feet.
If you're going to look at the prints with a magnifying glass, you'll need a medium format camera... be it digital or film.
With a normal SLR image ratio, 18*24 will be a cropped section from an 18*27 image. At 300 dpi, you'd require 18*300*27*300/1,000,000= 44 MP.
The top of the line Canon is under 17 MP, and this is already better than 35mm film.
