A MR method for measuring T2 relaxation times in tissues is proposed. The method is based on a T2 selective saturation followed by a conventional sequence. Saturation is accomplished by a single binomial RF pulse with constant flip angle. The T2 selectivity is controlled by the pulse duration. A full T2 spectrum can be obtained by performing a series of measurements with varying RF pulse duration. The method was used to acquire T2 spectra in pig liver on a conventional 1.5 T system in vitro. We observed a short T2 component around 17ms and an ultra-short T2 component around 1ms.
