For some tissues bSSFP shows a distinct asymmetry in its frequency response function. Theoretical considerations indicate that this asymmetry disappears in the limit of $$$\mathit{TR} \rightarrow 0$$$. This was studied experimentally at $$$3\,\mathrm{T}$$$ in the present work. The frequency response of bSSFP was investigated for in vivo brain for varying repetition time $$$\mathit{TR} = \{1.5,3,5\}\,\mathrm{ms}$$$. Our results give strong evidence that the asymmetry vanishes in the limit of $$$\mathit{TR} \sim 1\,\mathrm{ms}$$$ and therefore indicate that bSSFP forgets about the spectral composition and thus becomes ''pure''.
