The aim of this study was to describe the correlative characteristics of the hepatic topographic anatomy, making a connection with the data obtained in a quantitative way through the computed tomography exam of the hepatic radiodensity of free-living Carcarás (Caracara plancus). The components of the Falconiformes family make up a group of diurnal and nocturnal carnivorous birds such as eagles, falcons and caracaras. Its main feature is a curved beak and claws adapted to predation. The liver in this family is characterized by a larger size when compared to other bird families, which can reach 2.5% of body weight, it is divided into two lobes (right and left hepatic lobe), having the interlobar notch as a divider. Computed tomography is a technique where, using X-ray, sectional images of anatomical structures are obtained, which can be reconstructed in sagittal and axial sections for better visualization and understanding, thus allowing not only 3D reconstruction as well as accurate measurement. of radiodensity in Hounsfield units (HU) of live patients. Thus, it is a technique of choice for the study and monitoring of diseases that affect the liver parenchyma. The study's focal point is to correlate the tomographic description of the liver parenchyma of free-living Carcarás, linking information regarding the degree of normal radiographic attenuation. In this study, the mean value of hepatic radiographic attenuation of 52.47 ± 6.41 HU was obtained, ranging from 47.89 to 57.06. No statistical differences in the values obtained. The studies carried out allow the compilation of necessary information regarding the normal values of radiographic attenuation of the liver of free-living caracaras, thus providing reference values for the literature and serving as a basis for further studies.
