Table 1 Diagnostic performance of ECV and FIDDLE in canines and patients.

From: Accuracy of ECV imaging for the detection of subendocardial infarction - comparison with black blood delayed enhancement and pathology

  Sensitivity Specificity Accuracy
Overall - Animals

ECV 27% (11/41) 98% (166/170) 84% (177/211)
Subendocardial (<50% transmurality by pathology)
FIDDLE 93% (28/30) 100% (170/170) 99% (198/200)
ECV 3% (1/30) 98% (166/170) 84% (167/200)
