Comparative sensitivity of CT scans, radiographs and radionuclide bone scans in detecting metastatic calvarial...

CT scans of 100 patients with histologically diagnosed extracerebral neoplasms were reviewed and compared with either radionuclide bone images or skull radiographs. The results of this correlative study indicate that CT scans are more sensitive than skull radiographs in detecting corresponding calvarial lesions; conversely, radionuclide bone scans appear to be more sensitive than CT in detecting similar lesions.
