jMRUI

jMRUI performs time-domain analysis and management of magnetic resonance spectroscopy (MRS) and spectroscopic imaging (MRSI) data for metabolite quantification and reproducible processing workflows.

Key Features:

• Interactive processing of spectra: Analysis of single spectra and multidimensional MRSI datasets with capacity to quantify up to 20 metabolites involved in intracellular biochemical processes.
• History tracking and file identification: Robust tracking of processing steps and trials to manage complex analytical workflows and preserve processing provenance.
• Database integration and integrity: Java- and SQL-based database storing processing parameters and files with SHA-256 hash codes for unambiguous file identification.

Scientific Applications:

• Proton MRS metabolic studies: Non-invasive measurement and quantification of metabolites using proton magnetic resonance spectroscopy.
• Spectroscopic imaging analyses: Analysis of MRSI datasets to map metabolite distributions across tissues.
• Longitudinal studies: Tracking changes in metabolite concentrations over time for longitudinal biomedical and clinical research.

Methodology:

Time-domain signal processing algorithms are applied to MRS/MRSI data while processing parameters and files are recorded in a Java/SQL database with SHA-256 hashing for file identification.
