FIGURE 1

Three-dimensional spin lock–prepared pulse sequence components and imaging parameter definitions. Note that the durations and amplitudes are not drawn to scale. During the Mz recovery time (Trec), CSF nulling and/or fat saturation can optionally be applied. The entire segment is repeated until all views are acquired for a given spin-lock time (TSL). The full 3D acquisition is then repeated for each unique TSL. αn = flip angle of nth excitation pulse in the gradient-echo train; VPS, views per segment
