“…3 Imaging using B-mode ultrasonography only provides information about the shape, margins, and echogenicity of lesions, and may display similar features between neoplastic and benign soft tissue lesions, as reported in humans. 6,7 In this context, elastosonography has been introduced into both human and veterinary medicine as a tool for classifying the nature of mammary lesions, suggesting malignancy if decreased plasticity is detected. [8][9][10][11][12][13] Elastosonography provides information on tissue elasticity, assigning different elastic strains to different chromatic patterns.…”

Real-time elastography is a recently introduced ultrasound technique allowing the investigation of elastic properties of tissues. A diagnostic accuracy study was conducted to test the performance of this technique in the assessment of subcutaneous lesions in dogs. Fifty-two dogs were prospectively included in the preliminary study (34 malignant and 18 benign lesions). B-mode ultrasound was performed assessing the shape, margins, heterogeneity, and echotexture of the lesions. On elastosonography, assessment of the percentage of softness/hardness was recorded. A qualitative assessment was performed according to the Tsukuba elasticity score with a 1-5 score, representing the increased percentage of high stiffness areas. Results were compared with cytology/histopathology of the lesions. Receiver Operating Curves of the overall diagnostic sensitivity and specificity were obtained. Fisher's exact test and Pearsons's Chi-squared test estimated the relationship between the B-mode appearance of the lesions and final diagnosis. A hardness cutoff of 50.25% was identified between lesions, with malignant neoplasms having higher percentages. A 100% specificity and 89% sensitivity for correctly detecting the nature of the lesion on elastosonography was established. Qualitative assessment of the Tsukuba elasticity score established 1.5 as the cutoff between elastograms of lipomatous and malignant lesions, with 100% sensitivity and 61% specificity in differentiating them. Real-time elastosonography is a novel, noninvasive, and accurate technique for differentiating malignant from benign lipomatous lesions in dogs. This method could be considered as a complementary tool with additional diagnostic value for routine invasive procedures, such as fine needle aspirates.

Currently, according to World Health Organization, 132 000 melanoma incidences have been reported globally each year. 1 Alarmingly, Australia followed by New Zealand was reported to have the highest rate of melanoma in 2018. 2 In Australia, cutaneous melanoma is the third most commonly diagnosed cancer in both men and women aged between 15 and 39 years old. 3 Risk factors include prolonged exposure to the ultraviolet radiation from the sun causing sun burn, indoor tanning, personal and/or family history of melanoma and the phenotypic characteristic of fair skin. 4,5 If detected early in a localised state, melanoma is treatable by local excision; however, it can metastasise rapidly and become life threatening. 5 The case below describes an imaging journey of a patient who was diagnosed with a spindle cell melanoma in her arm, and the role ultrasound can play in the diagnosis.

“…Spectral Doppler techniques allow the diferentiation between venous and arterial low and the measurements of speciic parameters 'in real time', such as velocity (V), pulsatile index (IP) or resistive index (IR). Combining greyscale ultrasound with Doppler ultrasound allows the assessment of skin and skin lesions including morphology, size, shape, margins, macrocirculation, microcirculation and elasticity [13].…”

Psoriasis is a chronic inlammatory autoimmune disease that involves the skin, nails, joints and other organs, being a systemic disease. Regardless of the clinical form, sonography can be efectively used to complete the clinical diagnosis. Aim:The identiication of non-invasive sonographic markers for the assessment of the severity of the disease and the eicacy of various therapies. Our study involved two research directions: (a) clinical and imagistic assessment of the skin and nail psoriasis lesions and (b) the imagistic evaluation of the therapeutic eicacy in psoriasis plaques and nail psoriasis by acquirement of sonographic images prior and after various therapies. Methods:In our prospective study, we used a multimodal evaluation of the disease, based on a non-invasive approach: clinical exam, dermoscopy, conventional and high frequency sonography, Doppler, power Doppler and elastography. Conclusions:Ultrasonography is an important tool for the non-invasive assessment of psoriatic lesions. It ofers speciic markers related to morphology, elasticity and blood supply of the lesions, improving the diagnosis and monitoring of the skin and nail lesions.
