Overview
MRS measures biochemical compounds such as NAA choline and creatine to provide metabolic information complementary to structural MRI.
Technique
Single voxel or multivoxel spectroscopy requires careful voxel placement and shimming for reliable spectra.
Clinical Uses
Brain tumor characterization metabolic disorders and liver or prostate metabolic assessment.
Limitations and Safety
Lower spatial resolution and susceptibility to contamination from adjacent tissues. Interpretation requires expertise.
