Real-time tool to forecast the adequacy of shim and to define the number of acquisitions needed to answer the clinical question at hand with the prescribed 1H MR spectroscopy exam

Presently, the spectral quality in 1H MRS can only be determined after performing the time-consuming part of the exam, i.e. the recording of the water-suppressed spectrum. In clinical routine, there is often no time to re-record a spectrum if it turns out to be of bad quality. Therefore, we have developed a tool to forecast the spectral quality and to judge the adequacy of the achieved shim and proposed number of scans using a single-shot non-water-suppressed spectrum. To test, we acquired in vivo brain spectra and compared the forecast with the actual errors found by LCModel and jMRUI-QUEST.
