Figure 1.

Pulse sequence diagram of the proposed MRSI method without water suppression, allowing simultaneous detection of metabolite and water signals by two scans. Prior to a STEAM localization, two asymmetric narrow‐transition‐band adiabatic RF pulses invert the spectral range where metabolite signals are expected either upfield or downfield with respect to water. Instead of a conventional k‐space trajectory, the preparation scheme is followed by a concentric ring k‐space trajectory
