Multi-slice 2D FS PD sequence tends to be the sequence of choice for PD Fat Sat of the knee due to the relatively long scan times (5-6 minutes) and risk of motion artefacts associated with 3D PD FS imaging sequence. However a 3D sequence can offer an increase in coverage as well as SNR. Here we developed a PD FS 3D FSE sequence, which was modified to perform random CS undersampling followed by a custom reconstruction algorithm. In total 12 asymptomatic knees were imaged using the standard 3D PD Fat Sat protocol compared to the 3D PD Fat Sat with CS. The results showed that in all 12 knees the CS sequence reduced the scan time by 50% as well as providing diagnostic image quality.
