Some aspects of the computed tomography of the head

Computed tomography demonstrates intracranial neoplasms so clearly that nearly all early work in this field was limited to descriptions of the appearance of various lesions. Only recently have investigators directed their attention to the medical implications of the physical and pathophysiologic phenonmena that characterize this remarkable new technique. This paper will discuss recent work in these two areas and its clinical implications, and will examine the application of computed tomography to the evaluation of the postsurgical and postradiation patient.
