“…The most rostral aspect of the telencephalon corresponds to the olfactory bulbs. In the present study, the olfactory bulbs were consistently T2‐weighted hyperintense to the remaining brain parenchyma; this feature was not reported in previous studies describing the MRI anatomy of the avian brain . The cause of different signal behavior is unknown; one possible explanation is the laminar organization of the olfactory bulb, in contrast to the nuclear organization of the remaining parts of the telencephalon …”

“…The MRI features of the brain and celomic cavity of the domestic pigeon, as well as MRI features of the brain of canaries and European starling have been described . Magnetic resonance imaging has been proven to be useful to assess chronic sinonasal diseases in psittacine birds, diagnose hydrocephalus in African grey parrots, and has been shown to be superior to radiography in evaluating spinal cord trauma in three bald eagles .…”

Despite the increasing interest in the clinical neurology of birds, little is known about the magnetic resonance imaging (MRI) appearance of the avian central nervous system, eye, and inner ear. The objective of this cadaveric study was to document the MRI anatomic features of the aforementioned structures using a high-resolution 3.0 Tesla MRI system. The final study group consisted of 13 cadavers of the diurnal birds of prey belonging to six species. Images were acquired in sagittal, dorsal, and transverse planes using T1-weighted and T2-weighted turbo spin echo sequences. A necropsy with macroscopic analysis of the brain and spinal cord was performed on all cadavers. Microscopic examination of the brain was performed on one cadaver of each species; the spinal cord was examined in three subjects. Anatomic structures were identified on the magnetic resonance images based on histologic slices and available literature. Very good resolution of anatomic detail was obtained. The olfactory bulbs; cerebral hemispheres; diencephalon; optic lobe; cerebellum; pons; ventricular system; optic, trigeminal, and facial nerves; pineal and pituitary glands; as well as the semicircular canals of the inner ear were identified. Exquisite detail was achieved on the ocular structures. In the spinal cord, the gray and white matter differentiation and the glycogen body were identified. This study establishes normal MRI anatomy of the central nervous system, eye, and inner ear of the birds of prey; and may be used as a reference in the assessment of neurologic disorders or visual impairment in this group of birds.

“…However, the zoological use of such technology in more basic anatomical research has been rather limited. The few anatomical investigations incorporating CT and MRI technology include descriptions of the internal anatomy of the feline abdomen (Samii et al 1999), and the brain and coelomic cavity of the domestic pigeon (Romagnano et al 1996). The techniques have also been used in paleaontological studies, for example the measurements of brain size in Allosaurus (Rogers 1999).…”

-The 3-D skeletal images obtained from reconstruction of CT scans and X-rays, and soft-tissue images produced by MRI, provide invaluable information of the internal and gross anatomy of the north-western marsupial mole (Notoryetes caurinus).The conical skull, which is quite thin-walled dorsally and anteriorly but strong in the basicranial region, has little evidence of the orbit or zygomatic arch, and the smoothly-curved posterior region has no sagittal or occipital crests. The vertebral column is remarkably strengthened, and in lateral view has an unusual flat-shape. The cervical vertebrae appear to be greatly compressed; 4 or 5 are completely fused (which is unique among marsupials). The thoracic vertebrae are fairly robust with large neural spines. The lumbar vertebrae are distinct, becoming large posteriorly towards the pelvis. The sacral vertebrae are greatly expanded in size and are fused with the pelvis. Particularly in the middle of the tail, the caudal vertebrae are greatly developed, with large transverse processes and chevron bones. The pectoral girdle is very anterior, with the shoulder articulation level with the anterior cervical vertebrae just behind the skull, and low on the side of the body. The humerus is robust, and the radius and ulna are very short. The bones of the pelvis are highly derived, and fused to sacral vertebrae. The epipubic bones are small and not ossified. An ossified patella is present and it has an unusual large triangular keel.The most apparent soft-tissue structure by MRI is a large amount of subcutaneous fat, particularly around the ventral surface of the pelvis but also dorsal to the pelvis and anteriorly around the shoulders. The major muscle groups are visible, but distinction beh,veen individual muscles is not possible except for the very large muscles of the thigh, upper arm and base of the tail. The muscles of the tail are strongly developed, more so ventrally than dorsally.

“…No que diz respeito a TRMN em medicina de aves, pouca pesquisa tem sido feita para avaliar o seu uso nesses animais [83,84] . Encontram-se estudos que relatam o uso de imagens por ressonância magnética do cérebro e cavidade celomática de pombas domésticas [83] , do cérebro do canário e do estorninho europeu [85] , do olho e órbita normais de coruja [86] , do acúmulo de tecido intracranial em patos domésticos [87] , de psitacídeos com sinusite crônica [84] , de papagaios cinza para a mensuração da traquéia [88] , e mais recentemente, dos órgãos reprodutivos de pássaros canoros [89] .…”

Pensando bem...ser veterinário não é só cuidar de animais. É, sobretudo, amá-los, não ficando somente nos padrões éticos de uma ciência médica. Ser veterinário é acreditar na imortalidade da natureza e querer preservá-la sempre mais bela. Ser veterinário é ouvir miados, mugidos, balidos, relinchos e latidos, mas principalmente entendê-los e amenizá-los. É gostar de terra molhada, de mato fechado, de luas e chuvas. Ser veterinário é não importar se os animais pensam, mas sim sofrem. É dedicar parte do seu ser à arte de salvar vidas. Ser veterinário é aproximar-se de instintos. É perder medos. É ganhar amigos de pêlos e penas, que jamais irão decepcioná-lo. Ser veterinário é ter ódio de gaiolas, jaulas e correntes. É perder um tempo enorme apreciando rebanhos e vôos de gaivotas. É permanecer descobrindo através de animais, a si mesmo. Ser veterinário é o único capaz de entender rabos abanando, arranhões carinhosos e mordidas de afeto. É sentir cheiro de pêlo molhado, cheiro de almofada com essência de gato, cheiro de baias, de curral, de esterco. Ser veterinário é ter coragem de penetrar em um mundo diferente, e ser igual. É ter capacidade de compreender gratidões mudas, mas sem dúvida alguma, as únicas verdadeiras. É aliviar olhares, é lembrar do seu tempo de criança, querer levar para casa todos os cães vadios sem dono. Ser veterinário é conviver lado a lado com ensinamentos profundos de amor e vida. "Todos nós podemos nos formar em veterinária, mas nem todos seremos veterinários".
