Thirty post-surgical patients with various intracranial lesions were examined by both computed tomography (CT) and ultrasonography (US) to compare clinical efficacy. Ultrasonography with gray-scale electronic linear scanner was taken through post-surgical bone defect after routine CT examination had been completed. In fifteen patients, good correlation was obtained between these two modalities. As for d election of the hydro-cephalus, US showed 93% accuracy. In eleven cases, CT was superior to US in the diagnosis of brain edema and infarct. In four cases, US detected clinically useful information which CT failed to demonstrate. US can be a good imaging modalitv for post-surgical intracranial lesions. A certain portion of CT examinations can be replaced with US which will reduce the cost and radiation dose for the patient.
