One of the grants from CIHR is looking at ortho-iodohippuran for renal imaging. That's an agent I used 30 years ago. It's not a different agent, using iodine-131 versus iodine-123, but we already have the information.
The lymph node is a very important research project, lymphoscintigraphy. There are hospitals using that today in Ontario. So this is research that I think is important to gather information, but if I go back to ortho-iodohippuran, I was using that in 1978 as a technologist. So there are good things, looking at it, but it's almost as if we're reinventing the wheel a bit on certain aspects of this.
