Power Doppler in musculoskeletal ultrasound: uses, pitfalls and principles to overcome its shortcomings

摘要

Power Doppler (PD) is used widely in musculoskeletal ultrasound, especially in the assessment of structures for evidence ofinflammation and in evaluating soft tissue neoplasms. We reinforce and delineate the three cardinal principles of optimisingPD assessment in order to avoid false positive or false negative results; namely (1) Optimal gain settings (2) Adequatetransducer pressure, and (3) Proper patient/anatomical structure-of-interest positioning with complete tissue relaxation.
