Does texture analysis on nonenhanced cine MR images accurately diagnose subacute and chronic myocardial infarction compared to LGE imaging in patients undergoing cardiac MRI?
Effect estimate: AUC 0.93 for large MI, 0.92 for small MI
p-value: p=<.001
Texture analysis of nonenhanced cine MR images can accurately diagnose subacute and chronic myocardial infarction, potentially offering a diagnostic alternative that avoids gadolinium contrast.
Baeßler et al. (2017) conducted a case-control in Subacute and chronic myocardial infarction (n=180). Texture analysis on nonenhanced cine MR images vs. Late gadolinium enhancement (LGE) imaging was evaluated on Diagnosis of large and small MI on cine MR images (AUC 0.93 for large MI, 0.92 for small MI, p=<.001). Texture analysis of nonenhanced cine MR images accurately diagnosed large and small subacute and chronic myocardial infarction, with an area under the curve of 0.93 and 0.92, respectively.
