Decay curves of T2 and T2* for a healthy volunteer using: the three shim techniques (A, B), pixel sizes of 2 × 2 to 4 × 4 mm for T2 (C), pixel sizes of 1 × 1 to 3.28 × 3.28 mm for T2* (D), slice thicknesses of 8, 10, 12 mm (E, F), TR values 245–500 ms for T2 (G) and TR values 100–230 ms for T2* (H).
