Optiray is a special liquid used in adults for X-ray tests to help doctors see blood vessels, kidneys, and other body parts better.
Your doctor will decide the right dose for you, based on your test, health, and age, using the smallest amount needed.
A doctor or radiographer will inject Optiray into a blood vessel during your X-ray exam; it's warmed to body temperature first.
The doctor will always use the lowest possible dose that still allows for clear X-ray images.
