FIGURE 2.

Refocusing flip angles (top) and signal evolutions (bottom) for muscle and cartilage using 3 different refocusing flip angle schemes for ETL = 64. The flip angles were derived using the following control angles: (A) $\overrightarrow{\alpha }=\left[{20}^{\circ },{115}^{\circ },{60}^{\circ },{140}^{\circ }\right]$, (B) $\overrightarrow{\alpha }=\left[{20}^{\circ },{60}^{\circ },{60}^{\circ },{140}^{\circ }\right]$, (C) $\overrightarrow{\alpha }=\left[{80}^{\circ },{115}^{\circ },{60}^{\circ },{140}^{\circ }\right]$. The relative contrast is also shown for the contrast equivalent $T{E}_{eqv}$ of 75 ms
