A tomografia computadorizada quantitativa (TCQ) é uma técnica com alta sensibilidade, aplicabilidade e precisão no diagnóstico de perda de massa óssea, entretanto a falta de valores de normalidade para animais silvestres limita a sua aplicação clínica. O presente estudo objetiva estabelecer valores médios de radiodensidade do osso trabecular das vértebras dorsais, osso pleural e osso neural de tartarugas marinhas juvenis hígidas utilizando a TCQ. Para isso, utilizou-se um grupo experimental de cinco animais que foram submetidos a exames de tomografia computadorizada helicoidal, sendo as mensurações da radiodensidade óssea realizadas ao nível da terceira, quarta e quinta vértebras dorsais. Os valores médios de radiodensidade do osso trabecular das vértebras dorsais, osso pleural e osso neural foram, respectivamente, de 287,4±39,1, 1093,74±100,4 e 1089,6±86,5 unidades Hounsfield (HU). Estudos complementares devem ser realizados em diferentes espécies e faixas etárias de quelônios para favorecer a aplicação clínica desta técnica.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.
