CT/MRI Technology: Basic Principles

Abstract

Ever since the beginning of human stereotactic neurosurgery in 1947 [1], the radiological study has been an absolute prerequisite for the very existence of this surgery. Furthermore, the radiological study has always constituted an integral part of the surgical procedure itself. It was indeed the limitations of conventional radiology (plain X-ray, pneumoencephalography, ventriculography, arteriography), which for a long time did put the limits for what could be achieved with stereotactic neurosurgery.
