Quantitative and Qualitative Characterization of the Acute Changes in Myocardial Structure and Function after Distal Coronary Microembolization Using MDCT

Both visible and nonvisible microinfarct cause perfusion deficit and LV dysfunction. MDCT is sensitive for quantifying early functional changes in LV caused by microembolization. Further improvement in spatial resolution of this technology is needed to improve visualization of microinfarct.
