MRSI-data frequently contains
bad-quality spectra which strongly limits its clinical-use. Current clinical
practice in our institute is that these bad-quality spectra are filtered out by
an MRS-expert, at the expense of long processing times. In this work we present
a new method for automatic quality assessment of both long and short-TE MRSI brain tumour data. This method is based upon a novel
set of spectral features, and it is as accurate as an expert but considerably faster
(3/4 minutes vs 3seconds).
