DS has never, ever gotten a good xray from our local hospital/cf clinic. Since he was a baby they showed thickening, infiltration, and a number of issues. Then he'd have ct and lung scans at the hospital in the city and would get a clear bill of health. We're not sure if locally they're not experienced enough to interpret CF xrays, if the techs aren't getting a clear enough picture... but it's gotten to the point that we refuse to get annual chest xrays done locally.
