I’ll explain it like you're a child: RadioGel and YntraDose are not the same, not even close. RadioGel uses a special liquid that turns to gel inside a tumor and spreads tiny Y-90 particles evenly throughout it — locking radiation in place like concrete. YntraDose just glues Y-90 beads to one spot — like taping a flashlight to a wall and hoping it lights the whole room. RadioGel’s system is patented, FDA-tagged as a Breakthrough Device, and designed for broad tumor saturation. YntraDose can't copy it — totally different tech, delivery, and effect. So no, YntraDose isn’t “ahead” — it’s just different, and not a substitute.
