Main results of in vitro studies linking ICM with X-rays to DNA damage
| Experimental model | Effect |
|---|---|
| Cell types (lymphocytes) | DNA damage increased from 30% to 200% |
| ICM without X-rays | No effect |
| ICM added after X-rays | No effect |
| ICM pre-irradiated before mixing with blood | No effect |
| ICM irradiated with gamma rays | No effect |
| Increasing concentrations of iodine | Linear dose-dependent effect |
| Different ICM brands or manufacturers | No difference (only iodine concentration counts) |
