Resumo: | The purpose of this article is to review the literature on the essential technical aspects of implementing the pulsed Doppler, as part of the teachings to their use in the diagnosis of changes in the canine reproductive system. A narrative review was carried out, using scientific articles, monographs, theses and dissertations published and available in online databases: Periodical Capes (Coordination for the Improvement of Higher Education Personnel), SciELO (Scientific Electronic Library Online) and Google Scholar, in addition to specific books on the topic. Two-dimensional ultrasound has been widely used in medicine since 1942, leading to advancements in disease identification and subsequent prognosis. In terms of vascular assessment, Doppler ultrasound is used to evaluate the blood flow inside the vessel, its direction, and hemodynamic pattern. Among all types of Doppler ultrasound, the Color Doppler (CD), Power Doppler (PD), and the Pulsed-wave Doppler (PW) are commonly used in the identification of abnormalities through ultrasound flow imaging and the analysis of hemodynamic indices: peak systolic velocity (PSV), end diastolic velocity (EDV), resistance index (RI), and pulsatility index (PI). To accurately estimate these hemodynamic indices, however, it is essential to know the technical adjustments and parameters such as the pulse repetition frequency (PRF), size of the sample volume (Gate), angle of insonation, gain, baseline, and wall filter, which need to be corrected to avoid technician derive artifacts such as aliasing, signal absence, and mirror imaging. In medicine, the use of Doppler Mode in reproductive functions is already well established, but its use in veterinary medicine is still a subject of recent studies. |

Se realizó una revisión narrativa, utilizando artículos científicos, monografías, tesis y disertaciones publicados y disponibles en bases de datos en línea: Periodical Capes (Coordinación para el Perfeccionamiento del Personal de Educación Superior), SciELO (Scientific Electronic Library Online) y Google Scholar, además libros específicos sobre el tema. Desde 1942, la medicina ha ido evolucionando en la identificación de enfermedades y avances en el pronóstico, derivados del creciente uso de la ecografía bidimensional. En cuanto a la evaluación vascular, el Modo Doppler permite conocer la presencia de flujo sanguíneo, su dirección y patrón hemodinámico. Entre las modalidades, destacamos el Doppler color (CD), el Doppler de amplitud (PD) y el Doppler espectral o pulsado (PW), que permite la identificación de anomalías a través del espectro formado y mediante el análisis de índices hemodinámicos: Velocidad de pico sistólico (SPV), velocidad diastólica final (VED), índices de resistividad (IR) y pulsatilidad (IP). El conocimiento de los ajustes técnicos es fundamental para la correcta obtención de índices y parámetros como frecuencia de repetición de pulsos (PRF), volumen de muestra (Gate), ángulo de insonación, ganancia, línea de base y filtro de pared deben corregirse para evitar la formación de artefactos como el aliasing, ausencia de señal e imagen especular. En medicina, el uso del modo Doppler en funciones reproductivas ya está bien establecido, pero la investigación en medicina veterinaria es aún reciente.O objetivo do trabalho é realizar uma revisão de literatura sobre os aspectos técnicos essenciais para execução do Doppler pulsado, como parte dos ensinamentos para sua utilização no diagnóstico das alterações do trato reprodutor canino. Realizou-se uma revisão narrativa, utilizando artigos científicos, monografias, teses e dissertações publicadas e disponíveis nas bases de dados online: Periódico Capes (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior), SciELO (Scientific Electronic Library Online) e Google Acadêmico, além de livros específicos do tema. Desde 1942, a medicina experimenta evoluções na identificação de enfermidades e avanços para o prognóstico, advindas da crescente utilização do exame ultrassonográfico bidimensional. No que diz respeito à avaliação vascular, o Modo Doppler permite o conhecimento da presença de fluxo sanguíneo, sua direção e padrão hemodinâmico. Dentre as modalidades, destacam-se o Doppler colorido (CD), Doppler de amplitude (PD) e o Doppler espectral ou pulsado (PW), que permite a identificação de anormalidades por meio do espectro formado e pela análise dos índices hemodinâmicos: Velocidade de pico sistólico (VPS), Velocidade diastólica final (VED), Índices de resistividade (IR) e pulsatilidade (IP). O conhecimento dos ajustes técnicos é imprescindível para a correta obtenção dos índices e parâmetros como frequência de repetição de pulso (PRF), volume de amostra (Gate), ângulo de insonação, ganho, linha de base e filtro de parede devem ser corrigidos para evitar a formação de artefatos como aliasing, ausência de sinal e imagem em espelho. Na medicina, o uso do Modo Doppler nas funções reprodutivas já se encontra bem consolidado, mas na medicina veterinária as pesquisas ainda são recentes.Research, Society and Development2021-05-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1534810.33448/rsd-v10i5.15348Research, Society and Development; Vol. 10 No. 5; e52510515348Research, Society and Development; Vol. 10 Núm. 5; e52510515348Research, Society and Development; v. 10 n. 5; e525105153482525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/15348/13669Copyright (c) 2021 Camila Franco de Carvalho; Jéssica Ribeiro Magalhães; Andreia Moreira Martins; Kyrla Cartynalle das Dores Silva Guimarães; Reiner Silveira de Moraes; Daniel Bartoli de Sousa; Andréia Vitor Couto do Amaralhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCarvalho, Camila Franco de Magalhães, Jéssica RibeiroMartins, Andreia MoreiraGuimarães, Kyrla Cartynalle das Dores SilvaMoraes, Reiner Silveira deSousa, Daniel Bartoli de Amaral, Andréia Vitor Couto do2021-05-17T18:20:49Zoai:ojs.pkp.sfu.ca:article/15348Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:11.680037Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
