Micro-CT images acquired ex vivo from Nude BALB/c mouse skull (3D-volume rendering image). Displaying different anatomical regions: (a, a') lower and upper incisor tooth, (b) nasal bone, (c) frontal bone, (d) parietal bone, (e) intraparietal bone, (f) right mandible and (g) molar tooth. (A, B) Coronal views of cranial and caudal 34 areas of the skull, respectively, displaying in image A: (a) roots of the lower incisor, (b) frontal bone, (h) nasal septum, (i) maxillar/palatine bone, (j) mandible and (k) roots of molar tooth; in B: (d) parietal bones, (l) temporal line and (m) basis sphenoid bone. (C) Sagittal view of the skull displaying incisor roots (a, a'), nasal, frontal, parietal, intraparietal bones (b, c, d, e) and endoturbine structures (n). Micro-CT images from Nude BALB/c mouse hind foot (3D-volume rendering) showing the I-V phalanges, (l) tarso-crural joint, (m) metatarsal bone, (n) digital bone, (o) claw, (p) calcaneous bone. Examples of micro-CT C57BL/6 mouse femur showing coronal view and 3D-volume rendering image. (a, b, c) Close views of the proximal epiphysis (head and greater trochanter), metaphysis area displaying cortical and trabecular bone and the femur condyles, respectively. (d) Images displaying a sagittal 3D and 2D cross section of the proximal epiphysis (d', d'') and a sagittal cross view showing a map of the bone thickness with higher density areas displayed as white (femoral neck). All the samples were acquired at 80 kVp, 500 μA and with a pixel size of 9.5 μm; images were reconstructed in Hounsfield units (HU) and processed with ImageJ (NIH, Bethesda, MD, USA).
