Power Doppler (PD) is used widely in musculoskeletal ultrasound, especially in the assessment of structures for evidence of inflammation and in evaluating soft tissue neoplasms. We reinforce and delineate the three cardinal principles of optimising PD assessment in order to avoid false positive or false negative results; namely (1) Optimal gain settings (2) Adequate transducer pressure, and (3) Proper patient/anatomical structure-of-interest positioning with complete tissue relaxation.
能量多普勒(PD)广泛应用于肌肉骨骼超声,特别是在评估有炎症证据的结构和评估软组织肿瘤方面。我们强化并阐述了优化 PD 评估的三个基本原则,以避免假阳性或假阴性结果;即(1)最佳增益设置,(2)适当的探头压力,以及(3)适当的患者/感兴趣解剖结构定位,并使组织完全松弛。
