We present a novel,
simple and fast MR spectroscopic imaging technique and show its conceptual validation
with simulations and demonstrate proof-of-principle with phantom and human studies.
First, compared to the conventional spectroscopic imaging in the time-domain,
our method acquires data in the frequency domain, allowing flexible non-uniform
sampling to speed up the acquisition. Second, using ultra-small RF pulses
offers intrinsic water and fat suppression, greatly simplifying the scanning
procedures. Third, this new technique has hundreds of times lower energy deposition
than conventional MRI scans. We believe our method could allow spectroscopic
imaging to play a larger role in clinical applications.
