Abstract:
PURPOSE: To investigate whether and how the blood-oxygenation-level-dependent (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 have demonstrated a reduced BOLD signal in the tumor-bearing hemisphere. The BOLD signal variation in the motor cortex area was studied with finger tapping in a brain tumor group and a control group. An a priori volume-of...     »
