Improved Task-based Functional MRI Language Mapping in Patients with Brain Tumors through Marchenko-Pastur Principal Component Analysis Denoising

BACKGROUND: Functional MRI improves preoperative planning in patients with brain tumors, but task-correlated signal intensity changes are only 2%–3% above baseline. This makes accurate functional mapping challenging. Marchenko-Pastur principal component analysis (MP-PCA) provides a novel strategy to...
