| Zusammenfassung | Spatially selective excitation (SSE) with parallel transmission was applied as a means to acquire signal from anatomy adapted voxels for in vivo 1H MR spectroscopy. A novel method to select spectroscopy voxels with two-dimensional arbitrary shapes was investigated. An on/off scheme with an adiabatic slice selective inversion pulse preceding a 2D-SSE pulse enabled rapid free induction decay acquisitions. High spatial fidelity of the SSE profiles on and off resonance was achieved. Metabolite concentrations in human brain determined with SHAVE were reliably quantified with LCModel (CRLB ( 20 %) and did not deviate systematically from results acquired with a conventional SPECIAL sequence. |
