Abstract

Subcutaneous lesions in dogs are common in clinical practice. This prospective clinical study aims to compare B-flow and CEUS for the characterization of subcutaneous lesions evaluating their usefulness to distinguish benign subcutaneous lesions from malignant ones. Dogs were enrolled and ultrasound cine-loops were achieved in B-mode, Colour Doppler, Power Doppler, B-flow and CEUS. Lesions vascularisation highlighted through B-flow and CEUS were classified into five patterns: P1, absence of contrast uptake; P2, enhancement only in the peripheral area of the lesion; P3, thin (<2 mm) and few vessels (<5/field); P4, thicker (>2 mm) and more numerous vessels (>5/field); P5 enhancement with a reticular aspect and both thick and thin bands inside. Patterns highlighted with B-flow and CEUS were compared to a histological diagnosis of subcutaneous lesions. A total of 24 dogs and 30 subcutaneous nodules were included and divided into three groups: 3 non-neoplastic, 16 benign tumours and 11 malignant tumours. There was a statistically significant difference for B-flow and CEUS to differentiate benign tumours from malignant tumours. B-flow and CEUS had an excellent agreement. B-flow and CEUS displayed similar ability to evaluate different patterns and could be helpful in the evaluation of subcutaneous nodules.

狗皮下肿块和结节性病变的 B 型血流和对比增强超声 (CEUS) 特征。
狗的皮下病变在临床实践中很常见。这项前瞻性临床研究旨在比较 B 流超声和 CEUS 对皮下病变的定性,评估它们在区分皮下良性病变和恶性病变方面的作用。研究对象为犬只,并通过 B 型、彩色多普勒、动力多普勒、B 型血流和 CEUS 实现了超声成像环路。通过 B 型血流和 CEUS 显示的病变血管分为五种模式:P1,无造影剂摄取;P2,仅病变周边区域增强;P3,血管较细(2 毫米)且较多(>5/视野);P5,增强呈网状,内部既有粗带也有细带。将 B 流和 CEUS 突出显示的模式与皮下病变的组织学诊断进行比较。共纳入 24 只狗和 30 个皮下结节,并将其分为三组:3 个非肿瘤组、16 个良性肿瘤组和 11 个恶性肿瘤组。在区分良性肿瘤和恶性肿瘤方面,B-flow 和 CEUS 的差异有统计学意义。B 流和 CEUS 的一致性非常好。B-flow和CEUS在评估不同形态的肿瘤时表现出相似的能力,有助于评估皮下结节。
