Table 6 Patient reclassification when applying entropy

From: Phase analysis single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) detects dyssynchrony in myocardial scar and increases specificity of MPI

Patient group (N) Higher risk (%) Lower risk (%) No change (%) NRI (%)
Scar (40) 6 (15) 9 (22.5) 25 (62.5) − 8
No scar (98) 5 (5.1) 23 (23.5) 70 (71.4) 18
