Sažetak
Conventional x-ray is often used in scientific analysis of ancient remains, but so far only few articles describe the use of multi detector computed tomography (MDCT) in scientific study of ancient cremation urns. Magnetic resonance (MR) was used only once in the study of cremation urns, when Ultrashort echo time (UTE) sequence was used. Our aim was to assess the role of CT and MR in the analysis of urns excavated during the 2015 excavation. We have scanned eight (8) urns with cremated remains from Mačkovac, Croatia (Late Bronze Age). Axial 1.5 mm isometric CT slices were obtained using 16x1.2 mm with reconstruction increment of 1.5. Three-dimensional (3D), spoiled gradient echo based UTE images of specimen were acquired on a 1.5-T scanner (Magnetom Avanto, Siemens Healthcare, Erlangen, Germany) with manufacturer’s head coil. OsiriX software (Pixmeo, Geneva, Switzerland) was used for postprocessing. In all 7 specimen bones were always at the bottom of the urn and a thin layer of air between the bottom and bones is observed. Again it was almost impossible to define specific bones, but we recognized some pattern in grouping. MR provided better visualization of skeletal elements without soil signal but interesting artifact is described. We have another time concluded that CT provides new insights in acrhaeotanathology. Although CT has superior spatial resolution, it still has some important disadvantages: cremated bones have similar Hounsfiled units (HU) values to soil, which can be overcome with wider use of MRI in archeology.
