Table 1 Average values of estimation bias of \( {T}_{2s}^{\ast } \), and fbw for abbreviated with proposed bias correction and full UTE over a range of SNR levels. Bias values are averaged over a range of clinically relevant \( {T}_{2s}^{\ast } \) (0.5 ms – 2.0 ms) and fbw (0.70–0.95) values for ACL grafts and a fixed \( {T}_{2l}^{\ast } \) value of 20 ms

From: Abbreviated quantitative UTE imaging in anterior cruciate ligament reconstruction
