Radionuclide blood flow studies were employed to evaluate the success or failure of preoperative Gelfoam embolization in two patients with intracranial meningiomas. In both cases, the initial radionuclide blood flow study showed tumor visualization during the arterial phase. Immediately following the embolization procedure, the radionuclide blood flow study showed no visualization of the meningioma during the arterial phase, indicating a successful embolization procedure in preparation for removal of the tumor in a relatively bloodless field.
