3D images of barium sulfate perfused rodents. (A) Isosurface rendering of a six-month-old Sprague-Dawley rat cranium including blood vessels highlighted by barium sulfate. (B) Blood vessels of head of same rat, visible because of the dense perfusion fluid (barium sulfate) used. This image illustrates the vast vascularization of the internal and external compartments of the head. The rat head was scanned at 16 μm voxel size, 90 kV, 515 μA, 500 ms exposure time, with a scan time of 100 min. (C) Mid-diaphysis of a C57BL/6J mouse femur with barium sulfate-filled blood vessels highlighted. Scanned at 1.5 μm voxel size, 70 kV, 375 μA, 2000 ms exposure time, and 97 min scan time. (D) Inset of a small portion of the mid-diaphysis to illustrate the successfully perfused intra-cortical blood vessel.
