“…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 female dogs (Feliciano et al 2014b), and the spleen, liver and kidneys of adults dogs (Holdsworth et al 2014), splenic tissue in cats (Feliciano et al 2014a) and prostate and testes in dogs (Feliciano et al 2015).…”

“…Besides providing information about stiffness, ocular qualitative elastography enables a detailed assessment about morphology and structural composition, which is more information than conventional US provides. Previous studies showed that ARFI qualitative elastography can detect minimal echogenicity and echotexture changes, and can define the borders of neoplasms of many organic tissues better than other US methods (Khorramshahi et al, 2007;Săftoiu et al, 2007;Feliciano et al, 2014;Feliciano et al, 2015).…”

“…In veterinary medicine, ARFI elastography is a method to be explored, since its application, to date, has been exclusively in scientific investigations. In domestic or laboratory animals, ARFI elastography was already used to evaluate prostatic and testicular tissue, for the differential diagnosis of mammary neoplasms and to evaluate hepatic, renal, and splenic parenquima (Feliciano et al, 2014;Holdsworth et al, 2014;Feliciano et al, 2015;. There are no reports of veterinary medicine on the use of elastography in ocular evaluation of patients.…”

Eyes from brachycephalic dogs were studied by acoustic radiation force impulse (ARFI) elastography to establish quantitative and qualitative reference values related to the shape and rigidity of some ocular structures. Eighty-four eyes from 42 adult brachycephalic dogs were included in this study. Animals were subjected to physical, laboratory, and ophthalmic examinations. Following confirmation of good health, the dogs were subjected to ultrasonography and ARFI elastography, emphasizing the optic nerve, ciliary body, and lens. On qualitative elastography, homogeneous characteristics were observed on the ciliary body and optic nerve. Aqueous and vitreous humors were visualized as mosaic-like images. Quantitative elastography showed the mean optic nerve shear wave velocity (SWV) was 1.01±0.27m/s, temporal ciliary body was 0.91±0.24m/s, and nasal ciliary body was 0.91±0.3m/s. The SWV of the lens values were out of range, this value was not detectable by this software. Elastography has proved to be a non-invasive procedure and feasible in dogs. The establishmentof the parameters of degree of rigidity of ocular structures will serve as a baseline for animals with eye disorders. Results may be extrapolated to primary research on the applicability of ARFI in the evaluation of ocular bulb in humans.

“…Although few studies on contrast-enhanced ultrasound are published, this method, giving detailed information on the prostate gland vascularization, can be useful in detecting early prostate disease, in differentiate between malignant and benign lesions and in staging already diagnosed diseases (Bigliardi & Ferrari, 2011;Vignoli et al, 2001). Elastography evaluates the presence of deformities and tissue stiffness and, despite the few experimental studies about it, seems to be a useful diagnostic tool allowing to discriminate between a normal prostate and a pathological one (Domosławska, Zduńczyk, Jurczak, & Janowski, 2018;Feliciano et al, 2015).…”

Contents In small animal practice, prostatic diseases are increasingly encountered. All dogs may experience prostatic disease, but particular care should be addressed to breeding dogs, in which prostatic affection may lead to decrease in semen quality and fertility. The most common prostatic disease is the benign prostatic hyperplasia (BPH) followed by prostatitis, prostatic neoplasia and prostate squamous metaplasia. These diseases do not have pathognomonic symptoms, therefore, making a correct diagnosis may not be easy. An accurate clinical examination and a correct diagnostic protocol are essential in order to begin the most appropriate treatment, and also to do a good prophylaxis where it is possible. BPH therapy is usually recommended when mild‐severe signs are present or if symptoms disturb the patient. New therapeutic approaches, both medical and surgical, allow to maintain fertility in most animals with prostatic disorders. Prostate cancer is relatively infrequent. Elective therapy is the surgical one, but it is considered palliative and can result in important post‐operative complications. The aim of this paper is to lay down the most appropriate diagnostic process describing the aetiologies of prostatic disease, their symptoms, the right investigative tools and therapy.
