超声弹性成像是一种新的技术，可用于多器官病变的无创评估。本研究的目的是检查常规超声（US）与超声弹性成像的结合是否可以提高腮腺肿瘤评估的可靠性。43例腮腺肿瘤患者在耳鼻咽喉头颈外科的一个三级中心接受手术治疗。样本包括27名女性和16名男性，年龄15-80岁（平均年龄= 54岁）。对照组由54名健康志愿者组成。术前使用15 MHz线阵探头进行高分辨率灰阶超声检查（US）。弹性成像（ES）采用传统的Ueno 5分量表评分，从ES 1（蓝色-软）到ES 5（整个病变和周围区域着色为红色-硬）。此外，收集了以kPa为单位的详细刚度值。良性肿瘤33例，恶性肿瘤10例。10例恶性肿瘤（多为ES 4）的平均刚度值为146.6kPa; 33例良性肿瘤（多为ES 2和ES 3）的平均刚度值为88.7kPa。对照组中正常腮腺实质的组织硬度与检查组中所有肿瘤的平均值之间的差异具有统计学意义（p < 0.001），良性和恶性肿瘤之间的差异也具有统计学意义（p < 0.001）。2例恶性肿瘤和15例良性肿瘤的硬度评分为低（ES 1，2），8例恶性肿瘤和18例良性肿瘤的硬度评分为高（ES 3，4）。超声弹性成像与灰度图像重叠的弹性支持额外的信息。优先选择以高硬度（ES 4）为特征的病变可提高腮腺肿瘤的鉴别诊断，但也应指出这种方法的不确定性很大。
Sonoelastography is a novel technique, useful in a noninvasive assessment of lesions in multiple organs. The aim of the study was to examine whether the combination of conventional ultrasonography (US) with sonoelastography might improve the reliability of parotid tumor evaluation. Fourty-three consecutive patients with parotid tumors were surgically treated at a single tertiary center at the Department of Otolaryngology, Head and Neck Surgery. The sample included 27 women and 16 men, aged 15–80 (the mean age = 54 years). The reference group constituted of 54 healthy volunteers. High resolution grayscale ultrasonography (US) was performed preoperatively using a 15 MHz linear array transducer. Elastograms (ES) were scored by the conventional Ueno 5-point scale from ES1 (blue-soft) to ES5 (the entire lesion and surrounding area shaded red-stiff). In addition, detailed stiffness values in kPa were collected. The group consisted of 33 patients with benign and 10 patients with malignant tumors. The mean stiffness value was 146.6 kPa in 10 malignant tumors (mostly ES4) and 88.7 kPa in 33 benign tumors (mostly ES2 and ES3). The differences in tissue stiffness between normal parotid parenchyma in the reference group and the mean value for all tumors in the examined group were statistically significant (p < 0.001), and so was the case with the differences between the benign and malignant tumors (p < 0.001). Low stiffness scores (ES1,2) were found in 2 malignant and 15 benign tumors while high scores (ES3,4) were found in 8 malignancies and 18 benign tumors. Sonoelastography overlapping elasticity to the grayscale images supports additional informations. Preferential selection of the lesions characterized by high stiffness (ES4) improves the differential diagnosis of parotid tumors but the large degree of uncertainty of this method should also be pointed out.
