The actual MRI images — the scanner photographed her brain in thin slices. Everything in the 3-D view above is traced from these.

This scan, in numbers

Two colours, one disease.

Every one of her reports gives sizes for the red and no size at all for the blue — which is why her oncologist talks about the red, and he is right that it is the part to measure and act on. But the blue is not a separate thing sitting outside the tumour. Hers is an IDH-mutant astrocytoma, and in this type tumour cells are known to spread through tissue that never takes up dye; the international response rules written for it treat non-enhancing tissue as disease to be assessed, not as background. What these scans cannot do is say how much of her blue is tumour and how much is swelling and scarring from surgery and radiation. So: red is what gets measured and treated, blue is not proof that nothing is there, and neither outline is the true edge of the disease.

Every shape you see is traced from the real MRI images — nothing here is made up.

What the two colours mean

Red

The part the doctors measure

Blue

The area we keep an eye on

This area doesn't take up the dye, so the reports don't give it a size — but it isn't nothing, either. It's a mix the scan can't fully separate: some tumour, some swelling, and some healing from surgery and radiation. We watch it over time rather than measure it.

Two colours, but one thing being cared for. Neither colour is the exact edge — together they tell the story.

The story so far

Each dot below is one scan. The gap in the middle is the operation.

This is a friendly picture to help you understand the scans — not a medical report or a diagnosis. The numbers here are careful estimates, and your care team's report is always the final word. If anything worries you, bring it to them.
