“…Ultrasonography provides a method of accurately differentiating the types of cysts. The ultrasound appearance of follicular and luteal cysts have been documented [1,[3][4][5][107][108][109][110]. By ultrasonography, a follicular cyst appeared as a uniformly nonechogenic ovarian structure >25 mm in diameter with a wall <3 mm thick.…”

“…Characteristics of uterine disorders (endometritis, pyometra, hydrometra) have also been documented [1]. Ultrasonography has helped tremendously in the diagnosis and differentiating the types of ovarian cysts in cattle [2][3][4][5] and ovarian tumors [1]. The use of ultrasonography in monitoring the response to treatment of ovarian cysts in cattle has also been reported [3,6,7].…”

Abstract. The advent of ultrasonography over a decade ago has contributed tremendously in the field of bovine reproduction. Ultrasound imaging has shown that cattle exhibit 2 or 3 waves of follicular development during an estrous cycle. Ultrasonography allows monitoring of individual follicles as they grow and/or regress over time and patterns of follicular development can thus be determined with relative precision. Other important applications of ultrasonography in bovine reproduction includes; pregnancy diagnosis, fetal sex determination, folliculocenteses, diagnosis of abnormalities of the reproductive organs, monitoring of treatment of ovarian cysts, monitoring of postpartum genital resumption, ultrasound-guided centesis and male genital ultrasonography. Recent applications of ultrasonography in bovine reproduction includes doppler ultrasonography for genital blood flow and mammary ultrasonography. The use of ultrasonography is indispensable in most studies in which morphology (structure) and function are correlated. In this paper, the literature pertaining to the use of ultrasonography in bovine reproduction is reviewed. The applications and limitations of ultrasonography are highlighted. The non-invasive nature of ultrasonography makes it an excellent clinical and research tool in bovine reproduction.

“…Os equipamentos ultrassonográficos frequentemente utilizados não possibilitam a caracterização de folículos ovarianos em degeneração; no entanto, permitem diferenciar cistos com presença ou ausência de parede luteinizada (Siqueira et al, 2009). A eficiência, nesse caso, é limitada pela sensibilidade do equipamento e pela experiência do operador (Farin et al, 1990). A confirmação dos casos de cistos foliculares luteinizados é dada pela concentração plasmática de progesterona (P4) acima de 0,5 ng mL -1 (Kawate et al, 2011).…”

“…A alta sensibilidade do exame (91,5%) relatada por Farin et al (1990), entretanto, recorre no viés da maior prevalência de cistos foliculares luteinizados (70,1%), uma vez que os animais foram examinados antes e após o tratamento com hormônio liberador de gonadotrofinas (GnRH). Kawate et al (2011) também constataram maior ocorrência desse tipo de cisto com base no diagnóstico das concentrações de P4 ≥0,5 ng mL -1 .…”

Resumo -O objetivo deste trabalho foi avaliar a acurácia da ultrassonografia e da sintomatologia em determinar características funcionais de estruturas ovarianas císticas. Em 51 vacas Girolando sem corpo lúteo, foram avaliados: presença ou ausência de tecido luteal na parede do folículo; concentrações séricas de progesterona (P4); e sinais comportamentais dos animais (anestro ou ninfomania). As concentrações plasmáticas de P4 foram consideradas como padrão ouro. A avaliação ultrassonográfica foi um método preciso (82,4%) para diagnosticar o tipo de cisto folicular. O anestro está relacionado à presença de cisto luteinizado e à elevada P4. Os cistos não luteinizados são frequentemente encontrados em animais com baixa P4, que apresentam comportamento de anestro ou ninfomania.Termos para indexação: anestro, cisto folicular, cisto luteinizado, Girolando, ninfomania. Accuracy of ultrasound and behavioral assessment in determining functional features of ovarian cystic structuresAbstract -The objective of this work was to evaluate the accuracy of ultrasound and symptomatology in determining functional features of ovarian cystic structures. In 51 Girolando cows, without corpus luteum, the following were evaluated: presence or absence of luteinized tissue on the follicle wall; serum concentrations of progesterone (P4); and animal clinical signals (anestrus or nymphomania). P4 plasma concentrations were considered as the gold standard. Ultrasound evaluation was an accurate (82.4%) method to diagnose the type of follicular cyst. Anestrus is related to the presence of luteinized cysts and high P4 levels. Non-luteinized cysts are often found in animals with low P4, which exhibit anestrus or nymphomaniac behavior.
