CT of brain: technique for comparative postmortem slicing.

Traditionall y, the fi xed brain is sliced into sections in a coronal or horizontal plane for neuropathologic analysis. Computed tomography (CT) requires a reconsideration of this procedure and development of methods that allow for correlation of anatomopatholog ic aspects of lesions with correspond ing CT scan images [1 , 2]. This has been proposed by many authors and several techniq ues for accomplishing this have been presented [3 , 4]. However a simple method without complex equipment is needed so that it wi ll be used on a rout ine basis . The procedure we developed satisfies these criteria and is the substance of thi s paper. Th is method was applied with success on the brains of 20 patients who underwent CT examination prior to death.
