Abstract

X-ray computerised tomography (CT) was used for determining changes in the tissues of growing rabbits. Serial scans were taken on Pannon White rabbits weighing of 0.5, 1.5, 2.5 and 3.5 kg (5 animals per group). Twenty-four scans per animal were evaluated, from the scapular arch to the end of the femur. Three-dimensional (3D) histograms were constructed between -200 and +200 HU value, which represented the serial number of scans (24 scans) on the X axis, the density of the picture-forming pixels (in HU variables) on the Y axis, and the frequency of density values on the Z axis. The 3D histograms show the tissue composition of rabbit bodies, with different peaks corresponding to the scapular arch, the m. longissimus dorsi and the hindleg muscles. Fat depots were also definitely demonstrated, with different peaks in the scapular, abdominal and pelvic regions. The volume and the anatomical location of fat and muscle tissue were determined. An abrupt increase in fat content was observed between 2.5 and 3.5 kg of body weight.
