ABSTRACT: Wild species, especially those threatened with extinction, are increasingly being investigated to obtain information that can be useful for their preservation. The objective of the present study was to standardize the vertebral heart scale (VHS) and cardiothoracic ratio (CTR) of the collared peccary (Tayassu tajacu Linnaeus, 1758) sedated with ketamine and midazolam. Fourteen clinically healthy collared peccaries were examined in the two-year age group weighing 15-22kg. The animals were submitted to digital radiography of the thorax in lateral and dorsal ventral projections to calculate the VHS and CTR. The VHS mean values for males and females was 8.88±0.51v for right recumbency and 8.84±0.39v for left decubitus, and there were no significant between-gender differences regarding recumbency (p>0.05). The CTR showed mean values of 0.50±0.05 (males) and 0.45±0.04 (females), but the gender-differences were not significant (p>0.05). A positive correlation was shown between VHS and CTR (r=0.98, right decubitus; r=0.96, left decubitus). Establishing reference values for heart measurements in collared peccaries using digital radiography of the thorax permitted standardization of the VHS and CTR values for this wild species. In the studied wild animal model, the VHS and CTR heart assessment indexes were shown to be essential diagnostic tools for investigations of alterations in the size of the cardiac silhouette.

Abstract Thoracic Radiology is a diagnostic technique used to study several aberrations, including cardiac abnormalities, which can be determined by VHS (vertebral heart size). The heart length and width are measured, and the CTR (cardiothoracic ratio) is calculated, by comparing the heart width to the thoracic diameter. This study aimed at measuring the cardiac silhouette of non-human primates (PNH) belonging to the genus Sapajus sp., and the Alouatta guariba species through VHS and CTR. From among the eight animals assessed, it was evident that in both the Sapajus sp. and the Alouatta guariba, the highest HSV change index was observed, depending upon the age of the animal. However, although the individuals of the Alouatta guariba species are bigger in size and heavier, the animals of the genus Sapajus sp. have a larger heart size in proportion to their body.

Abstract: The VHS and CTR were assessed using computerized thoracic radiographs of ten clinically healthy tufted capuchin monkeys (five males and five females) from the Wild Animal Screening Center in São Luís (Centro de Triagem de Animais Silvestres de São Luís-MA-CETAS). Radiographs were taken in laterolateral and dorsoventral projections to calculate the cardiothoracic ratio (VHS) and vertebral heart size (CTR). The VHS showed mean values of 9.34±0.32v (males) and 9.16±0.34v (females) and there was no statistical difference between males and females (p>0.05). The CTR showed mean values of 0.55±0.04 (males) and 0.52±0.03 (females) and there was no statistical difference between the sexes (p>0.05). There was positive correlation between VHS and CTR (r=0.78). The thoracic and heart diameters showed mean values of 5.70±0.48cm and 2.16±0.40cm in the males, respectively. In the females they measured 5.32±0.39cm and 2.94±0.32cm. There was no statistical difference between the sexes. Our results show that the high correlation found between VHS and CTR permitted the verification with similar clinical precision between the two methods to estimate alterations in the heart silhouette by radiographic examination of tufted capuchin, making it an easy technique to apply that can be considered in the investigation of heart problems for this wild species.

Qualitative Analyses

This study aimed to evaluate the canine prostate using ultrasonography and digital radiography. The study involved 21 intact dogs of mixed breed, with a mean weight of 8.7 ± 3.09 kg and without previous hormonal treatment. The dogs were divided into three groups according to the age: GI (0-3 years); GII (3-7 years); GIII (7+ years). Prostates from each animal were qualitatively and quantitatively evaluated by means of digital rectal examination, ultrasonography and digital radiography. A total of 882 measurements were obtained and 84 qualitative analyses. The results demonstrated association and high agreement between digital rectal examination and radiography for prostatomegaly diagnosis (p = 0.0030; K = 0.829268). Ultrasonography and digital rectal examination did not present an association and had low agreement for diagnosis of alterations in prostatic parenchyma (p = 1; K = 0.049383). Also, there was a difference between ultrasonographic and radiographic measurements (height: p = 0.0002; length: p < 0.0001; width: p < 0.0001). However, the measurements from distinct radiographic projections showed no difference between each other (width: p = 0.3543; length: p = 0.3079 and p = 0.9725; height: p = 0.3208). Prostatic volume based on ultrasonographic measurements showed a positive correlation being proportional to the age of the dog (p = 0.0383). It was concluded that both methods, ultrasonography and radiography, are relevant diagnostic tools in evaluating the canine prostate, beyond just complementing each other. There are limitations associated with both imaging methods, which should be taken into consideration when planning a specific investigation of the canine prostate.
