Share:
- 1Non-ionic agents absorb more X-rays directly.
- 2Non-ionic agents do not dissociate into charged particles in solution, lowering osmolality.✓
- 3Non-ionic agents have significantly higher viscosity.
- 4Non-ionic agents are completely radiolucent.
Correct answer
Non-ionic agents do not dissociate into charged particles in solution, lowering osmolality.
