为了评价实时定性超声弹性成像作为常规超声检查的辅助手段来评估在常规临床实践中发现的非结节颈部肿块，49名患者的52个连续肿块接受了这两种技术。病变硬度在色度弹性图上从ES0-3(从低到高)进行视觉分级。诊断依据为(细胞学)病理(11例)、确证断层成像(18例)或特征性常规超声(23例)。其中脂肪瘤16例，淋巴管/静脉血管畸形15例，神经源性肿瘤/神经瘤6例，甲状舌管囊肿5例，皮样瘤5例，脓肿3例，第二弓裂囊肿1例，软组织转移1例。一般而言，神经源性肿瘤/神经瘤、皮样瘤和转移瘤的病变硬度较高(ES2-3)，而脂肪瘤、左心室肥大、TGCs和基底细胞癌的病变硬度较低(ES0-1)。脓肿的硬度随液体含量的不同而不同。确定了弹性图的技术限制和伪影。来自实时定性超声弹性成像的数据可能是超声诊断颈部非结节肿块的有用辅助工具(电子邮件：aniltahuja@cuhk.edu.hk)(C)2010年世界医学和生物学超声联合会。
To evaluate real-time qualitative ultrasound elastography as an adjunct to conventional sonography for evaluation of non-nodal neck masses identified in routine clinical practice, 52 consecutive masses in 49 patients underwent both techniques. Lesion stiffness was graded visually on chromatic-scale elastograms from ES0-3 (low to high). Diagnosis was based on (cyto) pathology (11), corroborative cross-sectional imaging (18) or characteristic conventional sonography (23). There were 16 lipomas, 15 lymphatic/venous vascular malformations (LVVMs), six neurogenic tumours/neuromas, five thyroglossal duct cysts (TGCs), five (epi)dermoids, three abscesses, one second-arch branchial cleft cyst (BCC), and one soft-tissue metastasis. In general terms, lesion stiffness was high (ES2-3) for neurogenic tumours/neuromas, (epi) dermoids and metastasis, and low (ES0-1) for lipomas, LVVM, TGCs and BCC. Abscesses displayed variable stiffness according to fluid content. Technical limitations and artefacts of elastograms were identified. Data from real-time qualitative ultrasound elastography may be a useful adjunct to sonography for diagnosis of non-nodal neck masses (E-mail: aniltahuja@cuhk.edu.hk) (C) 2010 World Federation for Ultrasound in Medicine & Biology.
