'Aroeira-branca' [Lithraea molleoides (Vell.) Engl. - Anacardiaceae] seed quality evaluation by the X-ray test Scientia Agricola
Machado,Cibele Ferreira; Cícero,Sílvio Moure.
'Aroeira-branca', an arboreal species of great ecological and economic importance, is seed propagated and presents limitations with respect to the availability of methods for seed quality evaluation. The X-ray test has been considered of potential value because it is accurate, quick and nondestructive. In this context, the objective of this work was to verify the possibility of this test to detect damage and/or abnormalities in aroeira-branca embryos, in an attempt to correlate these anomalies to germination. Four seed lots were collected in different locations in the southern region of the State of Minas Gerais, Brazil, during 2001. The X-ray test consisted of submitting 100 seeds/lot to radiation (exposure of seeds to radiation of 13 kV/5 minutes) and...

Aspectos clínicos e radiográficos de caprino com megaesôfago Arq. Bras. Med. Vet. Zootec.
Silva Júnior,L.C.; Arruda,L.C.P.; Silva,D.G.B.; Soares,F.A.P.; Borba Neto,A.V.; Leite,J.E.B.; Soares,P.C..
A seven month old female goat showed neck swelling, apathy, appetite and weight loss, restlessness, increased salivation, cough, and regurgitation episodes which occurred post feeding. The animal was evaluated through both clinical and radiographic examinations. Plain radiography was performed and contrasted X-ray was done using barium sulfate. For radiological examination, the lateral projection was used for analysis. The results showed a radiopaque content in the esophageal lumen dorsally positioned to heart with density and appearance similar to the rumen. A dilation of the esophagus was reported and a diagnosis of megaesophagus was made. In conclusion, contrast esophagography must be included in the diagnosis of megaesophagus in goats.

Comparative study between radiology and ultrasound in the evaluation of extracardiac thoracic diseases in dogs and cats Ciência Rural
Pires,Sâmara Turbay; Hage,Maria Cristina Ferrarini Nunes Soares; Pinto,Ana Carolina Brandão de Campos Fonseca; Hagen,Stefano Carlo Filippo.
ABSTRACT: This study compared radiographic and B-mode and Doppler ultrasound exams of the thoracic cavity, excluding the heart, in canine and feline species, in which the radiographs revealed the formation of a potential acoustic window. The objectives were to demonstrate the advantages and limitations of each technique and to determine whether the additional information influenced the differential diagnosis as well as the outcome of each case. The advantages of B-mode ultrasonography included: better qualitative and quantitative evaluation of pleural effusions, an improved ability to determine whether a nodule was solid or cystic and easier determination of the location in the pulmonary parenchyma. The Power Doppler ultrasound evaluated the blood supply...

Diagnostic value of computed tomography, radiography and ultrasonography in metacarpophalangeal joint disorders in horses Arq. Bras. Med. Vet. Zootec.
Machado,V.M.V.; Aguiar,A.C.S.; Viana,G.F.; Crosignani,N.O.; Puoli Filho,J.N.P..
In modern society the work and athletic performance of horses has led to a very important animal production sector in which Brazil possesses the third largest horse stock. Among all equine lesions described, metacarpophalangeal (fetlock) joint lesions are considered one of the main causes of lameness. Consequently, there is a need to improve the understanding and diagnosis of these injuries. The most efficient imaging diagnostic methods for the fetlock region are computed tomography, radiography and ultrasound. Imaging studies of the anatomical structures involving this joint are extremely important to obtain a more precise diagnose. The present study was performed in order to evaluate the capacity of different imaging diagnostic modalities to detect a...

Food passage time through the alimentary tract of a brazilian teleost fish, Prochilodus scrofa (Steindachner, 1881) using radiography Braz. J. Vet. Res. Anim. Sci.
BARBIERI,Renato Lamounier; LEITE,Rodolpho Guião; STERMAN,Franklin de Almeida; HERNANDEZ-BLAZQUEZ,Francisco Javier.
Food passage time through the digestive tract of a detritivorous freshwater fish (Prochilodus scrofa) was determinate by radiographic techniques using barium sulfate as a contrast medium. The fish were kept in tanks at a constant temperature of 23.5ºC and received by an oral catheter a mixture of 2.5 parts of ground ration and 1 part of oral suspension of contrast medium (Celobar). Radiographs were taken at intervals of 3 hours. Immediately after the introduction of the mixture the stomach was outlined by the contrast. A sphincter was observed between the cardiac and the muscular stomachs. After 3 hours, 80 per cent of the proximal intestine was filled. After 6 hours the contrast reached the proximal, medial and distal portions of the intestine. After 9...

Measurements of femoral angles, femur length, and hip width in cat radiographs Arq. Bras. Med. Vet. Zootec.
Fonseca,R.L.; Lobo-Jr,A.R.; Santana,M.I.S..
ABSTRACT Femoral angle, femur length, and hip width were measured in radiographs of 92 intact domestic cats, males and females of mixed breed from the Center for Zoonosis Control of the Federal District. The animals showed no trauma, orthopedic diseases or angular deformities and had closed physeal lines. Accordingly, we measured aLPFA (anatomical lateral proximal femoral angle, aLDFA (anatomical lateral distal femoral angle), mLPFA (mechanical lateral proximal femoral angle), mLDFA (mechanical lateral distal femoral angle), IA (femoral inclination angle), FL (femur length) and HW (hip width) using ventrodorsal radiographs, with both hindlimbs in a single exposure to an X-ray beam centered on the hip. The mean values of the variables were: mLPFA:...

Morphological Features of Pycnodysostosis with Emphasis on Clinical and Radiographic Maxillofacial Findings International Journal of Morphology
Alves,N; Oliveira,R. J; Deana,N. F; Sampaio,J. C. A.
Pycnodysostosis is a rare genetic syndrome characterized by short stature, obtuse mandibular angle, frontal, parietal and occipital bossing, open fontanels and cranial sutures, midfacial hypoplasia, acro-osteolysis of the distal phalanges, increased bone density, absence or hipopneumatization of the paranasal sinuses and normal laboratory studies. We report the case of a 35-year-old Brazilian man that was referred to a private clinic with history of dysmorphic facies for evaluation. The clinical and radiological features exhibited by the patient led to a diagnosis of pycnodysostosis. We describe the morphological features of pycnodysostosis with emphasis on the clinical and radiographic maxillofacial findings comparing the data obtained from our case with...

Ovarian radiographic and direct measurements of Japanese Quail ( Coturnix coturnix japonica ) submitted to light restriction Arq. Bras. Med. Vet. Zootec.
Albuquerque,M.; Guedes,R.; Dornbusch,P.; Laskoski,L.; Mangini,P.; Lange,R..
ABSTRACT Often, in pet birds, any stimulus to lay eggs is unwanted in order to reduce reproductive diseases and disorders. The objectives of this study were: to determine the time necessary to promote ovary involution after an eight hour photoperiod using laying Japanese quails (Coturnix coturnix japonica); to connect the ovarian radiographic measurements with egg production; and to compare these measurements with direct ovary data obtained at necropsy. Birds were separated into three groups: 12h/24d (control group - 12h photoperiod for 24 days), 8h/24d and 8h/36d (8h photoperiod for 24 and 36 days). After euthanasia, all cadavers were x-rayed to measure ovary length and height. Birds were necropsied to measure ovarian length and weight. Results:...

Photographic and Radiograpic Study of Osteological Abnormalities of the Head of Adult African Catfish (Clarias gariepinus) International Journal of Morphology
Olatunji-Akioye,A. O; Adeyemo,O. K; Akomolafe,O. T.
Radiography is a practical screening tool to detect subtle skeletal abnormalities in the adult catfish. Systematic identification of skeletal abnormalities in vertebrates provides an insight into the pathogenesis of skeletal disorders. In the present study; we conducted a mutagenesis screen for skeletal dysplasias in adult catfish, using photography and radiography to assess abnormalities in skeletal anatomy and bone morphology of the head. Two of the fish had skeletal protuberances on the head, while the third had a skeletal depression on the head with associated jaw deformity. However, there was no spinal involvement or other skeletal abnormalities. This study suggests a need for closer monitoring of cultured fish species; including dietary and...

Reading and interpretation of chest X-ray in adults with community-acquired pneumonia BJID
Moncada,Diana Carolina; Rueda,Zulma Vanessa; Macías,Antonio; Suárez,Tatiana; Ortega,Héctor; Vélez,Lázaro Agustín.
INTRODUCTION: Traditional reading of chest X-rays usually has a low prognostic value and poor agreement. OBJECTIVE: This study aimed to determine the interobserver and intraobserver agreement using two reading formats in patients with community-acquired pneumonia, and to explore their association with etiology and clinical outcomes. METHODS: A pulmonologist and a radiologist, who were blind to clinical data, interpreted 211 radiographs using a traditional analysis format (type and location of pulmonary infiltrates and pleural findings), and a quantitative analysis (pulmonary damage categorized from 0 to 10). For both, the interobserver and intraobserver agreement was estimated (Kappa statistic and intraclass correlation coefficient). The latter was...

Alsafy,Mohamed A. M; El-Gendy,Samir A.A; Abou-Ahmed,Howaida M.
The current study has been achieved to be an essential resource for all veterinary practitioners that deal with the anatomy of the carpal joint of the donkey. Ten adult donkeys of both sexes were used in the current study. The topographical approach to the carpal joint was investigated in this study. Radiography and computed tomography (CT) of the carpus delineated the articulations of the carpal joint: radiocarpal, intercarpal, and carpometacarpal. The carpal ligaments were well delineated and the carpal canal was demonstrated with its content such as superficial digital flexor tendon (SDFT) and deep digital flexor tendon (DDFT). The contrast radiography visualized that the radiocarpal joint outpouched proximal to the accessory carpal bone by large...
