Usefulness of the posterior cerebral flow study in subdural hematoma.
Anterior and posterior radionuclide cerebral flow studies and brain images were performed on two patients with surgically proven subdural hematoma. In both patients, the posterior flow study showed perfusion defects corresponding in location to the static image abnormalities. The anterior radionuclide flow study was negative in both patients, even though the abnormality in one of the patients was more anterior than posterior in location. On the basis of these cases, it is suggested that the performance of a posterior radionuclide flow study in suspected subdural hematoma might provide useful information not obtained on the routine anterior study.
