Anoxic brain injury | Radiology Reference Article - Radiopaedia.org
2024年5月30日 · Anoxic brain injury, also known as global hypoxic-ischemic injury, is seen in all age groups (from antenatal to the elderly) as a result of numerous etiologies. The pattern of injury depends on a number of factors including:
Anoxic brain injury CT and MRI patterns - ECR 2017 EPOS
MRI patterns of hypoxic/ ischaemic (anoxic) brain injury: 1. DWI is the earliest (within few hours) imaging modality to become positive (Due to cytotoxic oedema) Restricted diffusion is seen in most cases within cerebral cortex with predominance to sensory, visual and periolandic areas.
Diffusion-Weighted MR Imaging ofGlobal Cerebral Anoxia
1999年6月1日 · We analyzed diffusion-weighted and conventional MR images of patients with diffuse cerebral anoxia to determine their usefulness in establishing the diagnosis during the acute period and in determining the age of insult. METHODS: We reviewed 11 MR imaging studies of 10 patients who had experienced prolonged cardiac arrest.
Neuroimaging mimics of anoxic brain injury: A review
In this narrative review, we discuss a number of distinct etiologies of diffuse cortical diffusion restriction on MRI, the unique pathophysiologies responsible for tissue injury, and the resulting neuroimaging characteristics that can be of assistance in differentiating them.

In this narrative review, we summarize the most common imaging mimics of anoxic brain injury, along with their distinguishing clinical and neuroimaging features. The underlying pathophysiology of each mechanism of injury is also discussed. vasculature.
Neuroimaging mimics of anoxic brain injury: A review - PubMed
Diffuse cortical diffusion changes on magnetic resonance imaging (MRI) are characteristically ascribed to global cerebral anoxia, typically after cardiac arrest. Far from being pathognomonic, however, this neuroimaging finding is relatively nonspecific, and can manifest in a myriad of disease states …
Anoxic Brain Injury Detection with the Normalized Diffusion to …
2020年4月1日 · In this study, we sought to describe the nonquantitative ASL perfusion imaging patterns of anoxic brain injury, characterize the relationship of ASL and DWI, and evaluate a new metric: the normalized diffusion-to-perfusion (NDP) ratio to differentiate patients with anoxic brain injury from healthy controls.
Anoxic Injury-Associated Cerebral Hyperperfusion Identified with ...
2007年11月30日 · We present a series of 16 patients with a history of anoxic injury who demonstrated marked cerebral hyperperfusion on pulsed ASL perfusion imaging. We propose that this marked hyperperfusion is secondary to the loss of autoregulation of cerebral vascular resistance caused by the anoxic injury.
