Q-MRS: A Deep Learning Framework for Quantitative Magnetic Resonance Spectra Analysis
This work addresses data quality and quantification issues in MRS for studying tissue metabolism, particularly in central nervous system disorders, but appears incremental as it builds on existing deep learning and transfer learning methods.
The study tackled the challenge of balancing model complexity and reproducibility in magnetic resonance spectroscopy (MRS) quantification by introducing a deep learning framework using transfer learning, which showed promising performance on the Philips dataset from the BIG GABA repository.
Magnetic resonance spectroscopy (MRS) is an established technique for studying tissue metabolism, particularly in central nervous system disorders. While powerful and versatile, MRS is often limited by challenges associated with data quality, processing, and quantification. Existing MRS quantification methods face difficulties in balancing model complexity and reproducibility during spectral modeling, often falling into the trap of either oversimplification or over-parameterization. To address these limitations, this study introduces a deep learning (DL) framework that employs transfer learning, in which the model is pre-trained on simulated datasets before it undergoes fine-tuning on in vivo data. The proposed framework showed promising performance when applied to the Philips dataset from the BIG GABA repository and represents an exciting advancement in MRS data analysis.
