How OPTIRAY 320 Works

This agent works by opacifying blood vessels along its flow path, allowing for the clear visualization of internal structures until the substance is diluted by the blood. While it typically moves from the vascular system into surrounding tissues in the body, it remains within the vessels of a healthy brain unless the blood-brain barrier is disrupted.
