Computed tomography of local complications of temporal bone cholesteatomas.

abstract：:The authors describe a technique for automated analysis of lesions demonstrated by computed tomography. A seed circle may be superimposed on a lesion by an operator controlled program. By selecting density limits, the program will then automatically outline a particular area of abnormal density and calculate the stati...
