Breath-Hold trick may sharpen brain scans for tumor patients

This study looks at whether adding a breath-holding task to standard brain scans can make mapping of important brain areas more accurate in people with brain tumors. About 33 patients and healthy volunteers will have functional MRI scans while doing language tasks, with and without breath-holds. The goal is to see if the breath-hold method reduces false negatives, helping surgeons avoid damaging critical brain regions.
