Fig 2. Example of multiple spin-echo MRSI data (ETL = 6) in a patient with a meningioma, acquired with a 32 x 32 matrix in 5:12 (minutes:seconds). Post-gadolinium T1-weighted image (A), choline map (B), and NAA map showing the region (C) from which the spectra are depicted in D. The spatial resolution allows visualization of the change of metabolism from the tumorous region (high choline, no creatine, no NAA) to healthy metabolism outside the meningioma.
