Morphological affinities and demography of metal-age Southwest Asian populations.

abstract：:Cases of pathologically changed bone might constitute a diagnostic pitfall and frequently need histological methods to be etiologically properly evaluated. With micro-computed tomography (microCT), a new epoch of 2D and 3D imaging has been launched. We evaluated the diagnostic investigation of this analytical method v...
