Figure 4. CT Intensity in Regions with Low Voltage Area on EAM and Scar on LGE-CMR.
The mean CT intensities in normal myocardium with >1.5mV bipolar voltage on electroanatomic map (EAM) and no scar on LGE-CMR were 86.1±21.1 HU and, 80.3±17.0 HU, respectively. In addition, the mean intensities in transmural scar with 0.5mV> bipolar voltage and >75% scar transmurality were 20.7±36.9 HU and 21.9±12.2 HU, respectively. HU=Hounsfield unit, LGE-CMR=late gadolinium enhanced cardiac magnetic resonance
