Article Synopsis
- Functional magnetic resonance imaging (fMRI), especially at submillimeter resolution, is crucial for studying brain activity but faces challenges due to low signal-to-noise ratios (SNR), necessitating effective noise reduction methods.
- NORDIC PCA, a specific denoising technique, has been tested and shown to significantly enhance detection sensitivity and reliability in auditory fMRI data by minimizing noise-related variability.
- Although NORDIC may also slightly decrease signal amplitude, its ability to improve response consistency makes it valuable for high-resolution auditory fMRI studies, highlighting the need to assess signal reduction impacts based on the specific application.
The development of ultra high field fMRI signal readout strategies and contrasts has led to the possibility of imaging the human brain in vivo and non-invasively at increasingly higher spatial resolutions of cortical layers and columns. One emergent layer-fMRI acquisition method with increasing popularity is the cerebral blood volume sensitive sequence named vascular space occupancy (VASO). This approach has been shown to be mostly sensitive to locally-specific changes of laminar microvasculature, without unwanted biases of trans-laminar draining veins.
