Cranial computerized tomography. A radiologic-pathologic correlation.

One hundred twenty-three patients having cranial computerized tomography (CT) within two months of death were reviewed to determine the accuracy of CT. Those patients having scans within two weeks of death on the 160-matrix EMI head scanner had a false-negative rate of 11%. Approximately one third of all lesions 1 cm or more were not demonstrated. Computerized tomography appears to be the most sensitive neuroradiologic diagnostic tool, but certainly is not infallible.
