Abstract

This research demonstrates the application of diagnostic imaging techniques using soft X-ray radiography, computed tomography (CT) and magnetic resonance imaging (MRI) for non-destructive inspection of the northern smooth-tailed tree shrew (Dendrogale marina) . A non-invasive morphological observation is possible in each method. Soft X-ray radiography reveals the excellent skeletal system, but the soft tissue structures are projected with superimposition of morphological structures. However, 3-dimensional renderings of CT images can be manipulated toprovide images of the skin surface and skeletal system from any view, though spatial resolution was limited. Although MRI provides sectional morphological images in any plane, magnetic susceptibility artifacts from metallic foreign bodies were seen. Findings from this study suggest that medical imaging techniques can be successfully used for nondestructive interrogation of endangered animals. Yet it is important to remember that the selection of the imaging modality depends on its purpose.
