Tomografia computadorizada do encéfalo do cão: aspectos da normalidade e correlação anatômica

Abstract

RESUMOObtiveram-se imagens tomográficas sem alterações da cabeça de cães, visando à familiarização com os aspectos normais do encéfalo e correlacionaram-se os achados com a respectiva anatomia da região estudada. Várias estruturas anatômicas foram identificadas, tais como o parênquima dos lobos frontal, parietal, temporal e occipital, a fissura longitudinal, o sistema ventricular, o cerebelo, o bulbo olfatório, o corpo caloso, o diencéfalo, a ponte, a medula oblonga e o sulco quiasmático, de forma direta ou relacionando-as com estruturas vizinhas que auxiliaram na sua identificação.Palavras-chave: cães, encéfalo, anatomia, tomografia computadorizada ABSTRACT Normal tomographic images of dog's heads were obtained, aimed to familiarize them with the normal aspects of the brain and correlate these findings with the relevant anatomy of the region studied. Severalanatomical structures, such as the parenchyma of the frontal, parietal, temporal and occipital lobes, the longitudinal fissure, the ventricular system, the cerebellum, the olfactory bulb, the corpus callosum, diencephalon, the pons, the medulla oblongata and the chiasmatic sulcus were directly identified or were related to neighboring structures which helped in their identification.

Congenital dynamic cervical instability in a dog: the role of computed tomography and 3D printing to plan and optimize the surgical approach

“…In veterinary medicine, there are few reports of the use of 3D models for the surgical planning of patients with congenital vertebral malformations (Kamishina et al, 2019). In addition, CT and 3D printing technology are non-invasive planning techniques, which allow the training and planning of different approaches (Lorigados & Pinto, 2013).…”

Anatomical description of the skulls of peccaries (Tayassu tajacu, Linnaeus 1758) by computed tomography

“…In the present study, computed tomography provided excellent spatial resolution of the bone tissue of the skulls of peccaries. This advanced imaging diagnostic technique has been used to evaluate the heads of humans (Capello and Cauduro, 2008), horses (D'Août et al, 2015;Gonçalves et al, 2015;Liuti et al, 2017), buffaloes (Alsafy et al, 2013), canines (Rycke et al, 2003), pigs (Kyllar et al, 2014), felines (Losonsky et al, 1997), and goats (Moawad et al, 2017), among others. Our observations coincide with the descriptions made by Kyllar et al (2014) in pigs but differ from those of other domestic species due to phylogenetic, taxonomic, food and ecological distance.…”

“…Computed tomography is used less frequently in veterinary medicine than radiography; however, its widespread use is becoming more common, especially in small animals (Losonsky et al, 1997). The cost of CT scans hinders their routine use in clinical or experimental settings.…”

3D printing as a diagnostic tool for congenital malformation in a brachycephalic dog

“…In the present research , the rapid prototyping and computed tomography made it possible to accurately materialize the anatomical malformation area, as well as to visualize structures that were hidden or barely visible in the complementary exams (LORIGAdOS;PINTO, 2013;BORdELO, 2018), leading to the diagnosis of a congenital malformation that interconnects the trachea and the esophagus, affecting adjacent areas of soft tissue and creating air pockets along the oropharyngeal region. This hollow structure is responsible for choking, vomiting and breathing difficulties since there is no tissue separating the ducts (ALVES et al, 2013).…”

“…CLINIC ANd SURGERy the areas of neurology, traumatology, oncology, infectious processes and congenital abnormalities, enabling the definition of the best treatment protocol to be established (BORdELO et al, 2018), as well as the correlation of morphological changes with the clinical situation of each patient (BORdELO, 2018), in addition to providing the spatial dimensioning of the area of interest. Because they are noninvasive techniques, they provide exploration of different tissues, contributing to the quality of the diagnosis without harming the animal (LORIGAdOS; PINTO, 2013). This article focuses on a malformation linking the trachea, esophagus and adjacent areas in a male French bulldog puppy using CT and PR techniques to aid the diagnosis and prognosis.…”
