Table 2: Absolute average errors (SD) for TR 40 ms and TR 100 ms as a function of flip angle FA. Absolute average errors vary systematically as a function of FA. For TR 40 ms, the optimal flip angle is 30°, with an absolute average percentage difference PD of . For a TR of 100 ms, the optimal flip angle is 60°, with an absolute average percentage difference PD of .
