摘要： 目的探讨视频密度阶差（VDS）评价心肌微灌注的可行性及应用价值。方法11只比格犬使用聚苯乙烯微泡（直径100 μm）栓塞微小冠状动脉，栓塞后行冠状动脉造影并根据造影图像计算其VDS；并行心肌核素灌注扫描（SPECT），计算其心肌SPECT灌注积分。结果栓塞后的VDS为(15.2±3.8)；栓塞后的SPECT积分为(17.6±6.4)。VDS与SPECT积分呈负相关(r=－0.85, P<0.05)。结论VDS与心肌SPECT灌注扫描存在较好的相关性，可以作为临床上评价心肌微灌注的指标。

Abstract: ObjectiveTo evaluate the feasibility and the value of videodensitometric scale (VDS) in assessing myocardial microperfusion. Methods11 Beagles were embolized small coronary artery with polystyrene microbubble (100 μm). Coronary angiography was performed after the embolization and the VDS was calculated. Single photon emission computerized tomography (SPECT) was also performed after embolization and SPECT scores were also calculated. ResultsVDS after embolization was (15.2±3.8); and SPECT score was (17.6±6.4). VDS correlated negatively with SPECT scores (r=－0.85, P<0.05).ConclusionVDS keeps a closely correlation with SPECT. It can be used to assess myocardial microcirculation in clinical.
