Advanced MRI Techniques and Applications

Rapid cerebrovascular reactivity mapping: Enabling vascular reactivity information to be routinely acquired

This study reduces cerebrovascular reactivity mapping scan time from 7-12 minutes to 3-5 minutes using a sinusoidal stimulus, maintaining reliable CVR magnitude estimates.

Simultaneous GCaMP6-based Fiber Photometry and fMRI in Rats

This study demonstrates the feasibility of simultaneously recording calcium and BOLD signals in rats using GCaMP6-based fiber photometry and fMRI, showing reproducible responses to visual stimuli.

On the Origins of the Cerebral IVIM Signal

This study tests IVIM as an alternative to ASL for brain perfusion imaging but finds IVIM does not measure perfusion parameters and instead detects cerebrospinal fluid signals.

Low-Level Carbon Monoxide Exposure Affects BOLD FMRI

This study shows low-level CO exposure reduces BOLD FMRI signals during specific tasks, suggesting CO may confound neuroimaging results.

Differences in the spatial and temporal patterns of head motion during MRI of adults and infants

The paper quantifies differences in spatial and temporal motion patterns between adults and infants during MRI, finding distinct motion modes and distribution characteristics.

Slice-sampled Bayesian PRF mapping

This paper introduces a Bayesian approach to population receptive field mapping in fMRI data to quantify uncertainty in receptive field properties.
