Moderate and severe traumatic brain injuries (TBI) are a major cause of severe morbidity and mortality; rapid diagnosis and management allow secondary injury to be minimized. Traumatic brain injury is only one of many potential causes of altered mental status; head computed tomography (HCT) is used to definitively diagnose TBI. Despite its widespread use and obvious importance, interpretation of HCT images is rarely covered by formal didactics during general surgery or even acute care surgery training. The schema illustrated here may be applied in a rapid and reliable fashion to HCT images, expediting the diagnosis of clinically significant traumatic brain injury that warrants emergent medical and surgical therapies to reduce intracranial pressure. It consists of 7 normal anatomic structures (cerebrospinal fluid around the brain stem, open fourth ventricle, “baby’s butt,” “Mickey Mouse ears,” absence of midline shift, sulci and gyri, and gray-white differentiation). These 7 features can be seen even as the CT scanner obtains images, allowing the trauma team to expedite medical management of intracranial hypertension and pursue neurosurgical consultation prior to radiologic interpretation if the features are abnormal.

Nearly seventy years ago Wilhelm Worringer first wrote that ‘ultimately all our definitions of art are definitions of classical art’ (Worringer, 1953, 132). Today, the study of Western European art history, old or modern, the products of peasant craft-centres or urban ‘schools’, has in the course of time developed its own methodology and, almost, mystique. In contrast, the study of many branches of prehistoric art in Europe and elsewhere is all too often seen as a mere extension of the skilled but subjective approaches of classical archaeology without considering the suitability of the latter's application. The use of the classical art-historian's intuitive methods built up not just from visual exprience but a detailed background of literary, historical and philosophical studies must in fact be almost entirely denied the student of prehistoric or primitive art. It is perhaps only natural that principles of classical art history should be applied to later European prehistory, though it is often difficult to arrive at a precise definition of these principles. It was Johann Joachim Winckelmann who made the first systematic application of categories of style to the history of art (Gombrich, 1968, 319). Sir John Beazley, the greatest of all modern classical art historians followed in this tradition basing attributions ‘on the grounds of tell-tale traits of individual mannerisms’ (Carpenter, 1963, 115 ff.) a scheme first applied to painting less than a century ago by the Italian physician Giovanni Morelli (Gombrich, 1968, 309 ff.) and followed at the turn of the nineteenth century in the study of Italian painting (Lermolieff, 1892–3). With Beazley it is, however, difficult to follow step by step his methods of work.
