Intra-cardiac distribution of late gadolinium enhancement in cardiac sarcoidosis and dilated cardiomyopathy

Table 3 Diagnostic value of characteristic late gadolinium enhancement distribution patterns to differentially diagnose cardiac sarcoidosis from dilated cardiomyopathy

LE patterns	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
Striated	85.7	3.3	29.3	33.3
Nodular	57.1	96.7	88.9	82.9
Circumferential	35.7	96.7	83.3	76.3
Subepi + subend	50.0	96.7	87.5	80.6

PPV and NPV: Positive and negative predictive values; Sub-epi + sub-end: Subepicardial and subendocardial distribution with spared midwall; LE: Late gadolinium enhancement.
