Addendum to Microvascular dysfunction in HCM

Abstract

Signal intensity (SI) averages were measured for 16 myocardial sectors for each image of a dynamic series covering the first pass and recirculation of the injected contrast agent, using the AHA segmentation model. The resulting signal intensity curves and the associated times at which each image was acquired are used for determination of regional blood flow. Figure 1, reproduced here from the main body of the manuscript, provides an example of signal intensity changes in the inferior-septal segment, for rest and hyperemia. A region of interest (ROI) in the center of the left ventricle was used to sample signal intensity changes for the arterial input of contrast.
