(IR-FSPGR) This sequence uses an inversion pulse followed by a spoiled low flip angle and short TR gradient echo train to collect all partition data. The 3D-IR-FSPGR uses centric ordering of Gz. The selected TI is also the effective TI. The centric reordering strategy can lead to image blurring if a steady state is not achieved quickly with low flip angles (less than 20°).
