“…stress and elasticity decrease when depth increases). Thus, tissue depth becomes a limiting factor for this technique, particularly for assessing deep organs or obese patients (Carvalho et al, 2015;Feliciano et al, 2015a). Furthermore, in this technique the acquisition and interpretation of elastography image data is largely dependent on the experience of the examiner (Burnside et al, 2007;Chang et al, 2011).…”

“…In veterinary medicine, the ARFI technique is a recent development and has been used to evaluate focal liver lesions in rats (Carvalho et al, 2012), mammary tumours in bitches (Feliciano et al, 2014a), and queens (Feliciano et al, 2015c), prostate and testes in dogs , kidneys (Garcia et al, 2015), testes (Brito et al, 2015), and spleen in cats (Feliciano et al, 2014b), spleen, liver, and kidneys in adults dogs (Holdsworth et al, 2014), and spleen in healthy dogs of diff erent age .…”

Herramientas ultrasonográfi cas usadas en la evaluación del bazo en caninos: Revisión de literaturaFerramentas ultrassonográfi cas para avaliação do baço em cães: Revisão da literatura AbstractThe spleen is one of the most susceptible organs to primary tumours, metastasis, and a wide range of diseases of the hematopoietic system. Therefore, detailed assessment of the spleen is of great importance in veterinary medicine, especially in dogs, due to their economic and sentimental value, and as an experimental model in human medicine. Considering the recent advances in diagnostic imaging in companion animals, this review aims to describe the applicability of acoustic radiation force impulse (ARFI) elastography (qualitative and quantitative), Doppler, and contrast-enhanced ultrasonography for evaluating the spleen in dogs. The ARFI elastography is a recent ultrasound method that can provide reference values and aid in the diagnosis and evaluation of splenic abnormalities routinely encountered in veterinary practice. Conventional ultrasonography of the spleen combined with haemodynamic analysis by Doppler and contrast enhanced ultrasonography is an important tool in diagnosis and triage. Maronezi MC et al. Ultrasonography of dog spleen: A review ResumenEl bazo es uno de los órganos más propensos a desarrollar tumores, tanto primarios como metastásicos, y varias enfermedades que afectan el sistema hematopoyético. Es por eso que la evaluación clínica del mismo es de gran importancia en medicina veterinaria, principalmente en perros, debido a su valor económico, afectivo, y como modelo experimental en medicina humana. Considerando los recientes avances en imagenología diagnóstica, esta revisión tiene como objetivo describir el examen ecográfi co del bazo en perros, utilizando la técnica de elastografía por impulso de fuerza de radiación acústica (ARFI) cuantitativa y cualitativa, Doppler y ultrasonido contrastado. La elastografía ARFI es un método reciente que puede proveer información básica sobre la conformación normal del órgano y, en un futuro próximo, ayudar en el diagnóstico de las enfermedades esplénicas. De modo similar, la ecografía convencional, Doppler y el ultrasonido contrastado son importantes herramientas en el diagnóstico y en el triaje.Palabras clave: bazo canino, Doppler, elastografía, modo-B, ultrasonografía contrastada. ResumoO baço é um dos órgãos mais propensos a desenvolver tumores primários, metastáticos e afecções do sistema hematopoiético. Por isso, realizar uma avalição apurada neste órgão é de suma importância em medicina veterinária, particularmente em cães, devido à importância econômica, afetiva e de similaridade científi ca com o homem. Considerando os recentes avanços em diagnóstico por imagem, esta revisão visou descrever a aplicabilidade das novas técnicas ultrassonográfi cas para avaliação esplênica de caninos, utilizando a elastografi a por impulso de força de radiação acústica (ARFI) qualitativa e quantitativa, Doppler e ultrassonografi a por contraste com microbolhas.

“…The veterinary studies using this ARFI technique are recent and have been used to evaluate mammary tumors in female dogs (Feliciano et al 2014), spleen, liver and kidneys of adult dogs (Holdsworth et al 2014;Maronezi et al 2015), splenic and renal tissue in felines (Feliciano et al 2015a;Garcia et al 2015) and prostate and testicles in canines and felines (Brito et al 2015;Feliciano et al 2015b).

“…Qualitative ARFI is able to provide an elastogram of the relative stiffness of the tissue where lighter areas represent the more deformable tissues (Feliciano et al 2014). Quantitative study is related to the rigidity of the tissues, in which the velocity of propagation is capable of deforming the tissues, and higher velocity represents rigid tissues (Garcia et al 2015).…”

To describe the ARFI elastography in the evaluation of the adrenal glands in adult dogs, to evaluate the stiffness of adrenal parenchyma and to determine the qualitative and quantitative standards of the ARFI technique, which have not yet been described in veterinary medicine. Sixty adrenal glands from thirty healthy adult dogs were evaluated by B-mode and qualitative and quantitative ARFI elastography to assess the stiffness of healthy parenchyma and to determine the quality and quantity (shear velocity) standards of ARFI technique in body, cranial and caudal adrenal poles. Findings of ultrasonography evaluations were normal. Qualitative elastography showed that adrenal glands were not deformable and presented homogeneous middle-gray areas. The results of shear wave velocity were similar statically (P = 0.3087): 1) left adrenal -1.42 m/s for cranial polar, 1.31 m/s for body region, and 1.71 m/s for caudal polar; 2) right adrenal -1.42 m/s for cranial polar, 1.74 m/s for body region and 1.63 m/s for caudal pole. Quantitative and qualitative ARFI elastography of dogs' adrenal glands is feasible, well tolerated, easily implemented and may provide baseline data in the study of this structure to allow the use of ARFI.Keywords: canine, adrenal, ultrasound (P = 0,3087) RESUMO Objetivou-se descrever a técnica de elastografia ARFI na avaliação das glândulas adrenais em cães adultos, visando avaliar a rigidez do parênquima adrenal saudável e determinar os padrões qualitativos e quantitativos (velocidade de cisalhamento) da técnica ARFI, ainda não descritos em medicina veterinária. Sessenta glândulas adrenais de 30 cães adultos saudáveis foram avaliadas pela ultrassonografia modo B e pela elastografia ARFI qualitativa e quantitativa para avaliar a rigidez do parênquima saudável e determinar a velocidade de cisalhamento e padrões qualitativos da ARFI no corpo, polos adrenais cranial e caudal. As características ultrassonográficas das glândulas foram normais. A elastografia qualitativa mostrou que glândulas adrenais não se apresentaram deformáveis e homogêneas (coloração cinza médio). Os resultados da velocidade de cisalhamento foram semelhantes
