Safer brain scans: no contrast needed for meningioma detection?

This study tested whether special MRI sequences (FABIR) can spot meningiomas without using gadolinium contrast dye, which can build up in the body after many injections. Researchers compared the new method to standard contrast MRI in 315 adults undergoing screening or follow-up for meningioma. The goal was to see if the dye-free approach is accurate enough to replace contrast scans, reducing long-term risks for patients who need repeated imaging.
