OLIVEIRA, Jannine Forattini de et al. Densitometry of dorsal vertebrae, pleural bone and neural bone in healthy green sea turtles by quantitative computed tomography. Cienc. Rural [online]. 2012, vol.42, n.8, pp.1440-1445. ISSN 1678-4596. http://dx.doi.org/10.1590/S0103-84782012000800018.
Quantitative computed tomography (QCT) is a technique with high sensitivity, applicability and accuracy in the diagnosis of bone loss; however the lack of normal values for wild animals limits their clinical application. This study aims to establish medium values radiodensity trabecular bone of the dorsal vertebrae, bone pleural and neural bone in healthy juvenile sea turtles using the QTC. For this we used an experimental group of five animals that underwent helical computed tomography, and measurements of bone radiodensity conducted at the level of the third, fourth and fifth dorsal vertebrae. The medium values of radiodensity trabecular bone of the dorsal vertebrae, pleural bone, and neural bone were respectively 287.4±39.1, 1093.74±100.4, and 1089.6±86.5 Hounsfield units (HU). Further studies should be performed in different species and ages of turtles to encourage the clinical application of this technique.
