This review of laser Doppler flowmetry (LDF) focuses on indications and limitations in general and the author's experience of LDF in the assessment of tendon perfusion in particular. LDF is easy to use, minimally invasive and well suited for the study of relative changes in perfusion during rapid events. Problems specifically related to LDF include motion artifacts, a non-flow dependent output of unknown significance and uncertainty regarding the spatial resolution. The human Achilles tendon has a lower perfusion at the insertion but otherwise an even distribution of blood flow. Male gender, advancing age and mechanical loading of the tendon are associated with diminished tendon blood flow. The lesion in chronic degenerative Achilles tendinopathy is associated with hyperemia of uncertain origin.
本激光多普勒血流仪（LDF）综述重点关注其一般的适应症和局限性，特别是作者在评估肌腱灌注方面使用LDF的经验。LDF易于使用，微创，非常适合研究快速事件期间灌注的相对变化。与LDF具体相关的问题包括运动伪影、意义不明的非血流依赖性输出以及空间分辨率的不确定性。人类跟腱在附着点处灌注较低，但血流分布均匀。男性、年龄增长和肌腱的机械负荷与肌腱血流减少有关。慢性退行性跟腱病中的病变与来源不明的充血有关。
