Neuropathologic basis of computed tomographic scan abnormalities: a correlative method.
The accuracy of CT scan diagnosis can best be studied by comparing the postmortem scan to the corresponding pathologic specimen. To be valid, this comparison must be made in a precise manner: the CT image plane and the pathologic slice plane must correspond anatomically and must be juxtaposed in a specific point-to-point manner. A new method is described which correlates postmortem CT scans and postmortem pathologic specimens. Also considered are the utility and the limitations of matching CT absorption values to homogeneous pathologic lesions such as neoplasms, infarcts, hemorrhage and edema.
