The use of a simulated basis set for the analysis of 1H short-echo MRS data offers a number of advantages over an experimental basis set. One main advantage is that simulated basis sets can be easily regenerated for a particular echo-time or field strength without requiring hours of scanner time. In this study a comparison is performed between the metabolite quantities estimated by LCModel using simulated and experimental basis. A good correlation is seen between both methods suggesting that little bias is introduced by using a simulated basis set.
