## Abstract ## Purpose To investigate whether and how the bloodโoxygenationโlevelโdependent (BOLD) functional MRI (fMRI) signal is modified by brain tumors. ## Materials and Methods The BOLD signal depends on the perfusion, which in turn may be affected in the presence of a tumor. Some studies h

To decipher the biophysical mechanism behind the fMRI-BOLD response to apnea and its dependence on the baseline cerebral blood flow and oxygenation, fMRI and laser Doppler flow (LDF) studies were carried out in anesthetized rats. Baseline cerebral blood flow (CBF) and P a O 2 were modulated by venti
