Brains are composed of neurons, containing axons. Myelin aids in propagating electrical and chemical signals by insulating axons. Postmortem studies suggest that axon properties change with various neurological conditions. Imaging methods can aid in the diagnosis process and understanding how axons change over time. Electron microscopy (EM) is the current gold standard to measure...

Alzheimer’s disease (AD) is the most common form of progressive neurodegenerative dementia and a leading cause of death worldwide. The definitive cause of AD remains unknown, but its development is a multifaceted etiology. Early AD diagnosis is crucial as pathology begins decades before symptoms appear, and its diagnosis can only be confirmed post-mortem. Imaging techniques such as magnetic...

Magnetic resonance imaging (MRI) is a non-ionizing diagnostic technique that detects signals from hydrogen nuclear spins precessing in a strong static magnetic field, $B_0$. Metallic materials commonly used in orthopaedic and dental implants, such as titanium and cobalt-chromium alloys, introduce large magnetic susceptibility differences that significantly distort $B_0$. These distortions lead...

The Magnetization-Prepared Two Rapid Gradient Echo (MP2RAGE) pulse sequence acquires two high-resolution 3D volumes that are combined to produce a T1-weighted UNI image and a quantitative T1 map that is largely insensitive to B1+ inhomogeneity. In the brain, T1 relaxation is strongly correlated with myelin content, enabling in vivo assessment of neurological health. However, MP2RAGE scan times...

518. Towards a Standard Minimum Spectral Resolution for Broadband Continuous-Wave Near-Infrared Spectroscopy

Broadband continuous-wave near-infrared spectroscopy (bNIRS) is an effective technique for non-invasive neuromonitoring in neonates. However, most bNIRS devices are based on expensive custom-built spectrometers. The development of low-cost, compact, off-the-shelf spectrometers is critical for widespread clinical adoption. To guide this development, here we determine the minimum spectral...
