Correlation of Videodensitometric Scale and Single Photon Emission Computerized Tomography in Assessment of Myocardial Microperfusion / 中国康复理论与实践

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.
