The cranial traumas are a major cause of death and disability in young adults with an unfavourable outcome in more than 50% of patients. The methods of neuroradiological imaging represent the main diagnostic tool for managing the traumatised patient. CT allows a rapid assessment of the extent and type of brain damage that requires immediate surgical treatment. The increased ease of access to MRI acquired in recent times, can bring important benefits in the diagnostic assessment of cranial trauma due to its greater spatial resolution, particularly important in highlighting lesions in posterior fossa; the damage of white matter is detected easily and with great sensitivity by MRI. The high anatomical detail reached with modern the CT and MRI appliances, allows to define precisely the location, extent and characteristics of the damage caused by a skull-brain trauma. Nevertheless it is necessary to deepen the study of physiopathological aspects in order to explain the poor prognosis and severity of the clinical picture when the findings highlighted by " conventional" morphological methods show little alteration. Both CT and in MRI have had technological innovations in recent years; the CT, with the introduction of multislice helicoidal technologies, has got new chances and power; MRI, with new sequences of acquisition and stronger a magnetic field power, can explore even many functional aspects leading to better treatment and improving the final outcome. It was therefore appropriate to deal separately the predominantly morphological-structural methods and those which enable exploring some aspects of the pathophysiology of post-traumatic brain lesions. We now define "functional" these latest methods of technologically advanced imaging. Increased space was devoted to the classical imaging because of its wider diffusion and the clinical and practical weight. We present the most typical images of neuroradiological morpho-structural damage that characterize post-traumatic brain damage. In the field of functional imaging we list, in addition to the methodologies of strictly neuroradiological competence, even those in the field of nuclear medicine because these last ones also play an extremely important role, especially for the scientific research.
