We present here a novel MRSI approach combining spin editing and spiral data acquisition. Signal excitation was based on Selective Multiple-Quantum Coherence Transfer (Sel-MQC) technique that selectively excited protons in Poly Unsaturated Fatty Acids (PUFA). Fast spatial localization was achieved by 2-shot spiral imaging. One 2D image of PUFAs was acquired in 64 seconds.
