The Localization and Characterization of Ischemic Scars in relation to the Infarct Related Coronary Artery Assessed by Cardiac Magnetic Resonance and a Novel Automatic Postprocessing Method

Figure 1

The dotted line including box 2a and box 3a illustrates the automatic method for finding localization parameters for the myocardial scar, and the output is named LocParA (Localization Parameters Automatic). Box 2a represents the 3DmaxSI method from [14], which corresponds to the Full-Width-Half-Maximum (FWHM) criterion. Box 3a corresponds to the automatic localization parameter algorithm, first described by the authors in [13]. 2m and 3m correspond to manual demarking of the scar followed by a manual interpretation of the localization of the scar according to the AHA standard of 17 segments and the transmurality. The result is named LocParM (Localization Parameters Manual). In this paper, the findings of LocParA and LocParM are both compared to knowledge about which artery caused the infarction in the different patients.
