Regional Hypoperfusion Criteria for Abnormality
| Territory | Defect threshold (%) |
|---|---|
| LAD | 10 |
| LCX | 10 |
| RCA | 12 |
| CAD* | 3 |
↵* Left ventricular myocardium.
These criteria represent thresholds for stress abnormality, which were deemed to be best combination of sensitivity and specificity for each myocardial artery territory and for left ventricular myocardium. Hypoperfusion criteria for abnormality match those of our previously developed criteria for database quantification using SPECT or PET radionuclide.
