The common marmoset (Callithrix jacchus) is quickly gaining traction as a premier neuroscientific model. However, considerable progress is still needed in understanding the functional and structural organization of the marmoset brain to rival that do

High-resolution functional MRI studies have become a powerful tool to non-invasively probe the sub-millimeter functional organization of the human cortex. Advances in MR hardware, imaging techniques and sophisticated post-processing methods have allo

Magnetic resonance imaging radio frequency arrays are composed of multiple receive coils that have their signals combined to form an image. Combination requires an estimate of the radio frequency coil sensitivities to align signal phases and prevent

Many neuroscience applications have adopted functional MRI as a tool to investigate the healthy and diseased brain during the completion of a task. While ultra-high-field MRI has allowed for improved contrast and signal-to-noise ratios during functio

Respiration-induced movement of the chest wall and internal organs causes temporal B variations extending throughout the brain. This study demonstrates that these variations can cause significant artifacts in (Formula presented.) maps obtained at 7 T

Introduction: Pseudoprogression (psPD) is a transient post-treatment imaging change that is commonly seen when treating glioma with chemotherapy and radiation. The use of apparent transverse relaxation rate (R *), which is calculated from a contrast-

The magnetization-prepared two-rapid-gradient-echo (MP2RAGE) sequence is used for structural T -weighted imaging and T mapping of the human brain. In this sequence, adiabatic inversion RF pulses are commonly used, which require the B magnitude to be
