为了评价定性超声弹性成像对常规临床实践中发现的局灶性唾液腺肿块的诊断价值，对61例患者的65个腮腺或下颌下肿块进行了实时定性超声弹性成像，并根据其相对于相邻正常唾液腺实质的硬度（从ES 1（软）到ES 4（硬））对彩色弹性成像进行评分。其中Warthin瘤29例，多形性腺瘤23例，腺样囊性癌2例，腺鳞癌1例，鼻咽癌淋巴结转移1例，淋巴瘤1例（2个病灶），Kuttner瘤3例，Kimura病4例。ES评分显示根据病理状况的聚类。在这方面，PA比WT更坚固（P < 0.004，Fisher精确检验）。ES 1、2、3、4在良性肿块中分别为9、19、14、17例，在恶性肿块中分别为0、1、2、3、3例。所有三个原发性唾液腺恶性肿瘤ES 4相比，1/29 WT和16/23 PAs.These初步研究结果表明，定性实时超声弹性成像，虽然辅助技术，以传统的超声在唾液腺，可能有一个穷人的能力来区分良性病变（特别是PA）从恶性疾病。
To evaluate qualitative ultrasound elastography for focal salivary gland masses identified during routine clinical practice.Sixty-five parotid or submandibular masses in 61 patients underwent real-time qualitative ultrasound elastography and were scored on colour-scaled elastograms in terms of their stiffness relative to adjacent normal salivary parenchyma from ES 1 (soft) to ES 4 (stiff). This was correlated with diagnosis from aspiration cytology or histology.There were 29 Warthin's tumours (WTs), 23 pleomorphic adenomas (PAs), 2 adenoid cystic carcinomas, 1 adenosquamous carcinoma, 1 nodal metastasis from nasopharyngeal carcinoma, 1 lymphoma (2 deposits), 3 Kuttner tumours and 4 cases of Kimura's disease. ES scores showed clustering according to pathological condition. In this respect, PAs were firmer than WTs (P < 0.004, Fisher's exact test). Nine, 19, 14 and 17 of the benign masses and 0, 1, 2 and 3 of the malignant masses were ES 1, 2, 3 and 4 respectively. All three primary salivary malignancies were ES 4 compared with 1/29 WTs and 16/23 PAs.These preliminary findings suggest that qualitative real-time ultrasound elastography, although an ancillary technique to conventional ultrasound in the salivary glands, is likely to have a poor ability to discriminate benign lesions (particularly PAs) from malignant disease.
