Magnetic resonance spectroscopy (MRS) can provide
clinically valuable metabolic information for diagnosing
and treating breast cancer, but current acquisition
techniques need improvement. Single-voxel MRS (SVS)
gives good quality but requires expertise to acquire,
whereas chemical shift imaging (CSI) methods are easier
to acquire but give lower quality spectra. Our long-term
goal is to use a technique known as
Spectral
Localization by IMaging
(SLIM)
to reconstruct acquired CSI data, producing high-quality
spectra comparable to SVS but with the robust
acquisition of CSI. This work presents initial results
in breast cancer showing SLIM spectra that are
comparable or better than CSI.
