RF-spoiled gradient echo sequences (FLASH, SPGR, T1-FFE) require a spoiler gradient in order to suppress ghost artefacts. Here we show that two k-spaces can be adapted to the RF phase cycle such that averaging of them leads to elimination of these artefacts even if the spoiler gradient has only half of the moment that is requried for common RF-spoiled gradient echo acquisition.
