Abstract
Computed tomography (CT), since its introduction in the 1970s, has not only revolutionized radiology, but made all diagnostic algorithms faster and more accurate: for example, the presence of a subdural hematoma in a trauma patient before the invention of CT could be just suspected after an accurate neurological examination and by the presence of a fracture of the skull on a conventional x-ray. Nowadays, a CT scan performed in few seconds clearly shows the presence and the characteristics of the lesion.
