“MR Fingerprinting for Imaging Brain Hemodynamics and Oxygenation”

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Over the past decade, several studies have explored the potential of magnetic resonance fingerprinting (MRF) for the quantification of brain hemodynamics, oxygenation, and perfusion. Recent advances in simulation models and reconstruction frameworks have also significantly enhanced the accuracy of vascular parameter estimation.

Assessment of Small Vessel Density Changes in Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalophy (CADASIL) by High‐Resolution Black‐Blood MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Direct assessments of cerebral small vessels in Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) remain a challenge. Purpose To investigate changes of cerebral small vessels in CADASIL using iso‐0.5 mm black‐blood MRI. Study Type Case control study.

Predicting Breath Hold Task Compliance From Head Motion

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cerebrovascular reactivity reflects changes in cerebral blood flow in response to an acute stimulus and is reflective of the brain's ability to match blood flow to demand. Functional MRI with a breath‐hold task can be used to elicit this vasoactive response, but data validity hinges on subject compliance.

Pharmacological MRI: Utility in Understanding Drug Mechanisms in Psychiatric Disorders

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Pharmacological MRI (pharmaMRI) has emerged as a powerful tool to study how psychoactive drugs affect brain function and to uncover mechanisms of drug action in psychiatric disorders. This review provides an overview of key techniques used in pharmaMRI, including BOLD‐fMRI, arterial spin labeling (ASL), and cerebral blood volume (CBV) mapping,
