HR MAS analysis of intact tissues consists in the metabolic profiling of entire tumor biopsies using high resolution NMR (nuclear magnetic resonance) using 1H and/or 13C MRS (magnetic resonance spectroscopy). The technique allows combination of metabolomic data with genomic or proteomic data, and can therefore be used both for exploring the molecular biology of cancer and for clinical improvements in cancer diagnostics, prognostics, treatment planning, and treatment monitoring.
High Resolution NMR (600MHz magnet) equiped with a spinning system for HR-MAS (magic angle spinning) to allow study of intact tissues.

Pros, cons & Future potential
One of the best nondestructive method for study of biopsies composition.
Signal is better when acquired on tissue extracts.
No modifications are planned in the near future.
The technique will remain 'limited' to the analysis of tissue biopsies.
