Table 3.
Percent error of T2 estimates (relative to the gold standard) for the phantoms acquired with the liver data shown in Figure 7. T2 curves were reconstructed from undersampled data (4% sampled) using CURLIE or the REPCOM algorithm (which does not compensate for indirect echoes). T2 estimates from the CURLIE curves were obtained by SEPG fitting with “optimized” T1 (500 ms). T2 estimates from REPCOM were obtained using an exponential fit to the data.

| a | 53.2 | −2.3% | 6.4% | −3.2% | 20.7% |
| b | 77.9 | 1.0% | 14.4% | 3.1% | 38.9% |
