Table 1 Sensitivity and Specificity for Determination of T2 Enhancement

From: Severity of blood flow reduction associated with detectable T2 enhancement in the area at risk of a reperfused canine model of acute myocardial infarction

Image Analysis Optimal Threshold Sensitivity (%) Specificity (%)
Manual ROI 0.44 mL/min/g 100 100
16 sector matching (absolute flow) 0.50 mL/min/g 78 88
16 sector matching (relative flow ) 24% flow reduction 89 88
