Diagnóstico por imagem nas enfermidades tireoidianas em cães: revisão

The diagnosis of various diseases has become more accessible and accurate with the rapid development of imaging modalities aiming to assist in medical diagnosis, and thereby in veterinary medicine. Different diagnostic imaging modalities such as ultrasonography, computed tomography, magnetic resonance imaging and scintigraphy can be performed to obtain information about thyroid diseases, each one with advantages and disadvantages, depending on the thyroid disease in question. Diagnostic imaging is a tool that not only assists in the diagnosis, but also helps treatment and assessment of prognosis of thyroid diseases. The aim of this article is to discuss the limitations and benefits of each diagnostic imaging modality available in the veterinary medical field, and also to present the newest diagnostic imaging modalities in order to maximize and make more accurate diagnosis of thyroid diseases.

Condroma de sela turca associado a hipopituitarismo: relato de um caso

Os condromas intracranianos são raros, sendo mais comumente encontrados na base do crânio e na região esfenoetmoidal. Nesta localização podem ser confundidos com meningiomas, neurinomas e craniofaringiomas. Os autores apresentam a evolução clínica e as características pela imagem de um paciente portador de condroma da sela turca submetido a excisão tumoral.

Cisticercose intramedular: relato de caso e revisão da literatura

Os autores relatam um caso raro de neurocisticercose intramedular em um paciente do sexo masculino, de 36 anos de idade. Foram realizadas tomografia computadorizada e ressonância magnética do crânio, que evidenciaram múltiplas lesões de tamanhos variados, com realce periférico após injeção de meio de contraste. Também foi realizada ressonância magnética da coluna cervical, que evidenciou formação cística com escólex em seu interior ao nível de C5-C6 na região intramedular.

Análise da densidade óssea de rádio-ulna de cães SRD utilizando o método de imersão

Imaging diagnosis is a medical specialty that uses imaging techniques to perform diagnosis. In diagnostic imaging various methods are used such as direct absorption of photons - SPA and DPA, radiographic photometry, the dual-energy radiographic absorptiometry - DEXA, ultrasound, magnetic resonance imaging, computed tomography and optical densitometry in radiographic image. The dog can be considered one of the most widely used animals in the study of bone diseases and searching for a reliable diagnosis, although not an ideal model for the study of osteoporosis, because these animals tend not to develop a decrease in bone mineral density. The objective of this study was to analyze bone density in mongrel dogs from the determination of the variation of density along the radio-ulna bone and also the mean value related to gender, weight and age of individuals. The density analysis carried out showed that for this data set, there is a significant difference in the case of gender and age of the animal and may generalize according to these variables. The only significant difference was found in the weight, which increases bone mass is related to weight gain through the growth of the animal

Utilização da ultrassonografia transcuneal como auxílio no diagnóstico da síndrome do navicular em eqüinos

The equine locomotors system alterations are very frequent and corresponds a large portion of cases in equine medicine. The most equine veterinarian’s challenge is to do a precise diagnosis of lameness cause to perform a specific and proper treatment as early as possible. The navicular syndrome is considered responsible for one third of lameness causes and, although much studied, its etiology is still not fully understood. The most varied methods of diagnosis, such as x-ray, magnetic resonance, bursography, scintigraphy, computed tomography and ultrasound, have been used to assess podotrochlear apparatus situation in order to diagnose this syndrome. Among them transcuneal ultrasound can be used to observe some important structures such as the flexor surface of distal sesamoid bone, distal deep digital flexor tendon, distal sesamoid ligament entheses odd and the distal phalanx. The aim of this present paper is provide a brief review on the use and the technique of ultrasonography on third phalanx transcuneal region evaluation and its interpretation on navicular syndrome diagnosis in horses

Imageologia na odontologia e aspectos legais

The technology, through the advent of new equipments that allow imaging exams, has helped very much in the diagnosis and prognosis of diseases in Dentistry. The use of informatics, in general, in the manufacture of clinical reports is increasingly present in the dental offices. The legal validity of these systems is questioned, and is matter of discussion. This work makes considerations about Imageology or Diagnostic by image, a new area that is appearing on Dentistry. Among other exams, there are: digital radiography, tomography, computed tomography, artomography, magnetic resonance, computed cefalometry and ultra-sonography. It permits the professional to obtain a better diagnostic, and to the patient, the visualization of his problem and treatment. A survey on the possibilities of using informatics in Dentistry, particularly in Radiology, was also carried out, as well as the legal aspects, which are in accordance with the Law 8.935/94, what guarantees its practicability. Digital Certification is a mechanism that provides legal validity to documents and, as such, to radiographic images and others. It is a procedure that the dentist should take to ensure that he/she has safeguarded the judicial proofs that may be necessary in an eventual demand.

Comparison of imaging methods for diagnosis of renal tumors and their calcifications

Background: To establish the best methodology for diagnosis and management of patients with solid and complex renal masses by comparing the costs and benefits of different imaging methods and to improve differential diagnosis of these benign and malignant lesions, particularly by investigating tumour calcifications. Methods: We performed a prospective study on 31 patients with solid or complex masses by submitting them to Abdominal Ultrasonography (US), Doppler Ultrasonography of the renal mass (US Dop), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). Results: We found 28 patients with malignant and three with benign masses. Of the 28 malignant, 17 showed calcifications at CT; 16 central and one was of the pure peripheral curvilinear type (egg shell). Excretory Urography (IVP) had a significantly lower detection rate for central calcifications than both US and CT. Benign and malignant masses appeared as described in literature, with US, CT and MRI showing high sensitivity and specificity in renal tumor diagnosis. The exception was US Dop where we obtained lower sensitivity for the characterization of malignant tumor flow. Conclusions: In this series we were surprised to find that CT revealed central calcifications in 51.6% of patients, all with malignant lesions, while, literature reports a frequency of calcification in renal cell carcinoma between 8 and 22%, in studies using abdominal films and EU (IVP). This finding is of great importance when we consider that these calcifications occur particularly in malignant neoplasms. As a result of comparing these different imaging methods we have developed a better methodology for renal tumor investigation.

Síndrome de crouzon: fatores envolvidos no desenvolvimento neuropsicologico e na qualidade de vida

A síndrome de Crouzon é caracterizada por deformidade craniana, alterações faciais e exoftalmia. O retardo no desenvolvimento neuropsicomotor é observado em alguns casos. Este estudo tem como objetivo analisar a influência do momento da cirurgia, da classe sócio-econômica associada ao nível educacional dos pais e da ocorrência de malformações do sistema nervoso central no desenvolvimento cognitivo destes pacientes correlacionando estes achados à qualidade de vida deles e de suas famílias. Foram estudados 11 pacientes com diagnóstico de síndrome de Crouzon com idade entre um ano e quatro meses e treze anos. A avaliação multidisciplinar dos pacientes incluiu, avaliação social, avaliação cognitiva, estudo do encéfalo por ressonância magnética e avaliação da qualidade de vida. O quociente de inteligência variou de 46 a 102 (m=84,2) e foi correlacionado de forma inversa com o Fator 4 do Questionário de Recursos e Estresse Simplificado (incapacidade da criança); não se correlacionou com as alterações encefálicas, com a condição sócio-econômica dos pais e nem com o momento do tratamento neurocirúrgico.
