Assessment of LVEF by 5 Methods: Range and Lower Normal Limits
| Method | Gated SPECT (QGS) | Echocardiography | MRI | Angiography | ERNA |
|---|---|---|---|---|---|
| Mean LVEF ± SD (%) | 63 ± 10 | 60 ± 5 | 65 ± 5 | 67 ± 8 | 55 ± 7 |
| Lower normal limit (%) | 44 | 48 | 57 | 51 | 43 |
ERNA = equilibrium radionuclide angiography.
Data are from (87).
