Synchrotron-based DEI for bio-imaging and DEI-CT to image phantoms with contrast agents

The introduction of water, physiological, or iodine as contrast agents is shown to enhance minute image features in synchrotron-based X-ray diffraction radiographic and tomographic imaging. Anatomical features of rat kidney, such as papillary ducts, ureter, renal artery and renal vein are clearly distinguishable. Olfactory bulb, olfactory tact, and descending bundles of the rat brain are visible with improved contrast.

► Distinguishable anatomical structures features of rat kidney and rat brain are acquired with Sy-DEI in planar mode.
► Images of a small brain phantom and cylindrical phantom are acquired in tomography mode (Sy-DEI-CT) with contrast agents.
► Sy-DEI and Sy-DEI-CT techniques provide new source of information related to biological microanatomy.
