Sažetak
Since the invention of x-rays, paleoradiology, or paleoimaging, has played a significant role in the scientific study of ancient remains. Although x-ray units are used regularly, clinical computed tomography (CT) has been used only few times in the study of Bronze Age urns. At the University Department of Diagnostic and Interventional Radiology of the University Hospital Dubrava, we scanned dental remains found in 11 cinerary graves from the Late Bronze Age with a digitalized X-ray unit, (RAD Speed, Shimadzu Europe GmbH, Duisburg, Germany), an MDCT unit (Sensation 16 ; Siemens Healthcare, Erlangen, Germany) and a digital mammograph (Mammomat Nova, Siemens AG Medical Solutions, Erlangen, Germany). 3D reconstructions were made using Leonardo (Siemens AG Medical Solutions, Erlangen, Germany) and Aquarius (Terarecon Inc, San Mateo, SAD) workstations with OsiriX Imaging Software (Pixmeo, Geneve, Switzerland). CT scans allowed visualization of dental elements with better spatial and contrast resolution than mammography or plain x-ray images. The shape of the teeth has been evidently visualized on images and after 3D reconstructions, using volume rendering technique (VRT), maximal intensity projection (MIP), and surface rendering (SSD). Thermal modification following incineration presents a new challenge in paleoradiology as numerous differences exist between non cremated dental remains and thermally altered teeth. All techniques present limitations based on sample size. Although CT provides a spatial resoulution below 1 mm, it is still inadequate when it comes to differentiating small-scale elements. In spite of modest results, we strongly suggest a continuation of radiological analyses as they should help to form a wider evidence-based foundation for paleopathology.
