Spiral CT and Its Use in Neuroradiology: A Review of Spiral CT Techniques, Real-Time Volume Rendering, and Real Time Neuronavigation
X-ray computed tomography (CT) became widely available in the early 1970s, and by the 1980s CT had reached a plateau that few thought could be improved; the technology had matured fully. However, in the early 1990s a new breed of CT scanner appeared: spiral CT. By the mid-1990s it was apparent that scan protocols would need to be entirely rewritten in order to harness the power and speed of spiral CT. We, as radiologists and referring physicians, would have to reevaluate the clinical potential of CT for locating disease. This chapter addresses a small part of this réévaluation: the role of spiral CT in neuroradiology and neurosurgery.
