I didn't notice too much of a difference, as it was only one treatment. I went in twice and inhaled radioactive saline and then the 2nd time was a radioactive surfactant. They watch how it spreads through the lungs and the speed at which it does. I think the end point is going to be to mix antibiotics like Tobi in surfactant to help it spread across the lung surface better than it would mixed in saline.
I will talk to Tim and see if he has crunched all of the numbers yet.
