Usefulness of sagittal computed tomography in neurosurgery.

Sagittal section tomographic images can be obtained either directly or by an electronic reconstructing procedure. These two techniques are extremely useful for neurosurgeons because it is possible to obtain a better clinical and pathological evaluation of the lesion. This procedure is almost recommended in case of pituitary adenoma, cerebello-pontine angle neoplasms, orbital lesions and brain-stem lesions. The authors show the results of the experience of the University of Pavia and discuss the true indications to this neuroradiological technique.
