27 patients with confirmed Sjögren's syndrome were examined prospectively by means of colour coded duplex sonography and pulsed Doppler sonography in order to determine blood flow in the parotid gland in this condition. Organ perfusion was divided semi-quantitatively into 4 groups: grade 0 (no intraglandular perfusion recognised) to grade 3 (numerous intra-glandular flow signals). Low perfusion values (grade 0 or grade 1) were found in normals and this was also observed in 13 patients (48%). 6 patients (22%) showed moderate increase (grade 2), and 8 patients (30%) showed gross increase (grade 3) in glandular perfusion. The increase in perfusion correlated with the severity of the sono-morphological glandular changes, such as reduced echogenicity, increased size and heterogeneous structure. Increased perfusion was associated with intra-glandular flow velocity as measured by Doppler sonography; maximal systolic flow velocity was significantly higher in patients with markedly increased perfusion than in normals.
对27例确诊为干燥综合征的患者进行了前瞻性彩色编码双功超声和脉冲多普勒超声检查，以确定该疾病状态下腮腺的血流情况。器官灌注被半定量分为4组：0级（未识别到腺体内灌注）至3级（大量腺体内血流信号）。正常个体中发现灌注值较低（0级或1级），13例患者（48%）也观察到这种情况。6例患者（22%）显示中度增加（2级），8例患者（30%）显示腺体灌注显著增加（3级）。灌注增加与腺体超声形态学变化的严重程度相关，如回声降低、大小增加和结构不均一。灌注增加与多普勒超声测量的腺体内血流速度相关；灌注明显增加的患者最大收缩期血流速度显著高于正常个体。
