Short echo time MR spectroscopic imaging for neonatal pediatric imaging.
A short echo time (30 milliseconds) MR spectroscopic imaging pulse sequence was implemented for applications of neonatal brain imaging. Multiple spatial saturation bands were used to eliminate strong signals originating from the subcutaneous lipids to enable volumetric region coverage. Metabolite signal intensity-to-noise ratio < or =40 was acquired in 9 minutes of scan time over an 8 x 8 x 8 spatial matrix with 1 cm(3) isoresolution.
