Keywords: Analysis/Processing, AI/ML Image Reconstruction
Motivation: To accurately quantify γ-Aminobutyric acid (GABA) and other metabolites useful for diagnosis of neurodegenerative diseases from edited magnetic resonance spectra.
Goal(s): Our goal is to illustrate the accuracy and robustness of our proposed neural network, MegaNet.
Approach: The analyses of Bland-Altman were performed on the quantification results between MegaNet and LCModel, and between the quantification results of MegaNet on data of low quality and ordinary quality.
Results: MegaNet has good consistency with LCModel and shows robustness to noise-corrupted data.
Impact: It shows that synthetic data learning with physical prior knowledge is probably a reliable method to address the problem that AI training of magnetic resonance spectroscopy (MRS) lacks abundant high-quality data.
