“…This technique facilitates the volumetric study of organs and structures, besides it, provide a third image plane, the coronal plane, which allows more precisely volumetric calculation mainly those of irregular shapes. The 3D ultrasonography is still a new technique in veterinary medicine, and few are the scientific papers that report its experimental use [ 8 ].…”

Aim:The objective of this study was to obtain and compare two-dimensional (2D) and three-dimensional (3D) ultrasonographic images of the urinary bladder in different disease conditions.Materials and Methods:The present study was conducting on total 10clinical cases of the urinary bladder in dogs. The ultrasound (US) machine used for this study was 3D US machine (Nemio-XG: Toshiba, Japan) having a four-dimensional volumetric probe.Results:In the present study, the inflamed thickened wall was clearly visible with the distinction of different layers of the urinary bladder wall in some of the cases of cystitis using 2D ultrasonography. In 3D sonogram, the urinary bladder was visualized as a large anechoic structure with no distinction of different layers of the bladder wall. The cystoliths were clearly visible as hyperechoic structures with distal acoustic shadow in 2D sonogram and appeared as a bright echogenic area in 3D sonogram. In case of urinary bladder neoplasia in 2D ultrasonogram, the bladder lumen was found to be occluded with a large growth imaged as focal anechoic areas in the tissue of mixed echogenicity with small hyperechoic dots in this tissue parenchyma. In 3D ultrasonogram, a tissue of mixed echogenicity of pus was also observed.Conclusion:From the present study it was concluded that 2D and 3D ultrasonography is very helpful for diagnosis of different clinical conditions of the urinary bladder such as cystitis, cystoliths, and urinary bladder neoplasia. The cavity of urinary bladder was more clearly visualized in 3D ultrasonography, but the distinction of different layers of the bladder wall was visualized only in 2D ultrasonography. The distinct shadow of pus and cystoliths were visible in 2D ultrasonogram. The visualization of pus in 3D ultrasonography was done for the first time in present study.

“…Three-dimensional (3D) ultrasonography is an emerging technology that has been developed to estimate gallbladder volumes. This method has been shown to be an accurate and appropriate tool for the measurement of organ volume in both dogs and humans [ 2 , 6 , 13 , 14 , 15 , 16 , 24 , 29 , 30 ]. A potential advantage of 3D ultrasonography for measuring gallbladder volume is that a sagittal section of the gallbladder at its maximal diameter is not required, which may be useful in patients with irregular gallbladder shapes.…”

Three-dimensional (3D) ultrasonography has been shown to be an accurate and appropriate tool for measurement of gallbladder volume in humans. Therefore, we applied this novel technique for the first time to study fasting and postprandial gallbladder volume in 10 healthy dogs and compared the results with those of 2-dimensional (2D) ultrasonography. Fasting gallbladder volumes determined by 3D ultrasonography were significantly higher than corresponding volumes determined by 2D ultrasonography (P<0.01). Additionally, gallbladder volumes were significantly decreased in the postprandial state compared with the fasting state using 3D ultrasonography (P<0.001), but 2D ultrasonography showed no significant difference (P=0.189). The Gallbladder contraction index was higher in 3D ultrasonography than 2D ultrasonography; however, it did not reach statistical significance (P=0.25). In conclusion, 3D ultrasonography was able to measure gallbladder volume in healthy dogs in this study. It is suggested that 3D ultrasonography can be used to accurately estimate gallbladder volume and contractility.

“…Exemplificando, Mendonça et al (2012) avaliaram pela ultrassonografia 3D o parênquima renal de cadelas gestantes e identificaram aumento de 6,5% no volume renal durante a gestação, referindo que tais dados indicam a existência de alterações volumétricas renais consistentes, devido as alterações morfológicas e funcionais prováveis durante a gestação.…”

RESUMO:A presente revisão tem por objetivo descrever as atuais utilizações da ultrassonografia tridimensional (US 3D/4D) em obstetrícia veterinária de pequenos animais. A ultrassonografia tridimensional surgiu na década de 1950 e começou a ter maior aplicabilidade nas áreas de obstetrícia e ginecologia no início dos anos 1980. Essa técnica ultrassonográfica 3D facilita o estudo volumétrico de órgãos e estruturas e por permitir um terceiro plano da imagem (plano coronal) possibilita o cálculo volumétrico mais precisamente, principalmente aqueles órgãos com formato irregular. A modalidade 4D é utilizada na avaliação de estruturas e funções via correlação imagem espaço-temporal. Mesmo sendo uma técnica disponível há mais de 30 anos em medicina humana, na veterinária os estudos são recentes e necessários para demonstrar a especificidade e sensibilidade da técnica ultrassonográfica na rotina da obstetrícia de pequenos animais.Palavras-chave: Pequenos animais. Ultrassonografia volumétrica. Obstetrícia. GESTATIONAL ULTRASONOGRAPHY 3D/4D IN SMALL ANIMALSSUMMARY:This review aims to describe the current use of three-dimensional ultrasonography (U.S. 3D/4D) in small animal veterinary obstetrics. The three-dimensional ultrasonography emerged in the 1950s and started to have wider applicability in the areas of obstetrics and gynecology in early 1980. This technique facilitates volumetric study of organs and structures and allow a third image plane enables volumetric calculation more accurately, especially those irregularly shaped bodies. The 4D method is used to evaluate structures and functions via image correlation temporal space. Even being a technique available for more than 30 years in human medicine, in veterinary studies are needed to demonstrate the specificity and sensitivity of the technique in routine obstetric ultrasound of small animals.
