HISTORY: Trauma. Fractures. Intracranial hemorrhage and edema. Altered mental status. Evaluate cerebral perfusion.
RADIOPHARMACEUTICAL: 20.3 mCi Tc-99m Tc99m pertechnetate i.v.
FINDINGS: The anterior cerebral radionuclide angiogram demonstrates good perfusion through the common carotid arteries and branches of the external carotid arteries, but there is no visualization of the internal carotid arteries, anterior or middle cerebral arteries, a cerebral capillary phase, or the superior sagittal sinus. Activity within the right facial region likely due to hyperemia related to facial and calvarial fractures is noted. The subsequent static images in anterior and lateral projections demonstrate no visualization of the dural sinuses. These findings indicate absence of effective cerebral perfusion.
IMPRESSION: No effective cerebral perfusion.
