Transverse Hadamard spectroscopic imaging (T-HSI) has been shown to overcome the intrinsic signal-to-noise loss and increased bleed of chemical shift imaging by virtue of its approaching-ideal point-spread-function. However, because it uses a superposition of pulses, it is less suited for higher fields where the available B1 is smaller. In this work we demonstrate a method that overcomes this limitation and allows maintaining the benefits of T-HSI despite the higher (3T) field strength.
