Abstract
En 中文
Late gadolinium enhancement (LGE) assessed by cardiovascular magnetic resonance is the cornerstone in the assessment of myocardial tissue characterization, providing crucial diagnostic and prognostic information across a wide spectrum of cardiac conditions. While LGE is traditionally evaluated for its presence and extent, a comprehensive assessment of its diverse characteristics, called “LGE granularity”—including its location, extent, and pattern—offers deeper insights into myocardial pathophysiology.
