Figure 4 The receiver operating characteristic curves of contrast-enhanced cardiac magnetic resonance imaging with the measurements of percent transmural enhancement (dotted line) and with measurements of thickness of nonenhanced myocardium (solid line) for detecting preserved contractile function in the chronic state. The area under the receiver operating characteristic curve with the measurements of thickness of nonenhanced myocardium was significantly higher than that with the measurements of percent transmural enhancement for both scans 1 and 2.
