This was tested in people. That is the most reliable kind of research we share.
This was a small study in people that only compared scans to what surgeons found, so it is not yet a proven tool.
The short version
A special MRI measure lined up with how firm brain tumors turned out to be during surgery.
What was studied. Doctors looked at 33 people who had meningioma surgery between May 2022 and January 2025. In 22 of them, they compared a measure taken from an MRI scan before surgery with the firmness of the tumor tissue measured during surgery.
What they found. The scan measure matched up with how firm the tumor was. Lower scan values went with firmer tumors. Higher scan values went with softer tumors. The link held up even when tumors treated with embolization were left out.
What this means, and what it doesn't
What it could mean: How firm a meningioma is can affect the surgery, including how it is reached and how much can be taken out. If a scan can hint at firmness ahead of time, surgeons may be able to plan better. This would not need any extra procedure, since it uses an MRI scan.
What it doesn't mean: This does not mean a new treatment. It is not a cure, and it is not a promise about how surgery will go. This was a small look back at 22 people at one center. The scan measure only covered selected solid parts of the tumor, not the whole tumor. It has not been tested in a large study, and it is not yet part of everyday care. Ask your own care team what their plan is.
