OBJECTIVE
A new sonoelastography technique - virtual touch tissue quantification of acoustic radiation force impulses (ARFI) - offers a promising method for measuring tissue rigidity. The aim of this study was to assess the usefulness of ARFI for diagnosing Sjögren's syndrome (SS).
METHODS
This transversal prospective study included 41 patients with SS according to American-European Consensus Group (AECG) criteria, and a control group without symptoms. All subjects underwent ARFI high-resolution ultrasound assessment of the parotid glands (PG) and submandibular glands (SMG).
RESULTS
In patients with SS, parotid gland shear wave velocity (SWV) was 2.08 m/s ± 0.55, significantly higher than in control subjects (1.2 m/s ± 0.17) (P = 0.0001); submandibular gland SWV was higher in SS patients (2.12 m/s ± 0.44) than control subjects (1.56 m/s ± 0.16) (P = 0.001).
CONCLUSIONS
Acoustic radiation force impulses sonoelastography can assist diagnosis of SS, and is a non-invasive and fast method of detecting pathological changes to the parotid and submandibular glands.
目的
一种新的超声弹性成像技术——声辐射力脉冲虚拟触诊组织定量分析（ARFI）——为测量组织硬度提供了一种有前景的方法。本研究的目的是评估ARFI在诊断干燥综合征（SS）中的作用。
方法
这项横向前瞻性研究纳入了41例符合欧美共识小组（AECG）标准的SS患者，以及一个无症状的对照组。所有受试者均接受了腮腺（PG）和颌下腺（SMG）的ARFI高分辨率超声评估。
结果
SS患者腮腺剪切波速度（SWV）为2.08 m/s±0.55，显著高于对照组（1.2 m/s±0.17）（P = 0.0001）；SS患者颌下腺SWV（2.12 m/s±0.44）高于对照组（1.56 m/s±0.16）（P = 0.001）。
结论
声辐射力脉冲弹性成像可辅助SS的诊断，是一种检测腮腺和颌下腺病理变化的无创且快速的方法。
