Since its invention in the early 1970s, magnetic resonance imaging (MRI) has revolutionized medicine and biology. However, its applications thus far have been limited primarily to structural imaging and functional imaging. Professor Liang’s research group has made major advances in overcoming the long-standing technical barriers of label-free molecular imaging using MR spectroscopic imaging. This ultrafast MRSI technology is based on a new approach to spatiospectral imaging, achieving an unprecedented combination of resolution, speed and SNR for MRSI. In this talk, Professor Liang will give a brief overview of this new technology and show some exciting results that his research group has obtained.
