Amide proton transfer imaging-arterial spin labeling mismatch: a new imaging biomarker for pilocytic astrocytoma

Scientific Reports, 2023
We describe the potential utility of Amide Proton Transfer weighted (APTw) Magnetic Resonance Imaging and arterial spin labeling (ASL) in characterizing pilocytic astrocytoma (PA), a type of brain tumor that can be challenging to accurately diagnose and ...

Histogram-Based Analysis of Low- and High-Grade Glioma and Its Surrounding Edema Using Arterial Spin Labeling Magnetic Resonance Imaging

Applied Sciences, 2023
A glioma is a type of intra-axial brain tumor originating from the glial cells. Making up about one-third of all brain tumors, a timely diagnosis alongside correct grading and subsequent therapy planning is crucial.

Unilateral anoxic brain injury secondary to strangulation identified on conventional and arterial spin-labeled perfusion imaging

Radiology Case Reports, 2018
Anoxic brain injury on magnetic resonance imaging classically demonstrates symmetric diffusion restriction involving the highly metabolic structures including the basal ganglia and cortex and global hyperperfusion on arterial spin labeling perfusion. The

Measurement of brain perfusion in newborns: Pulsed arterial spin labeling (PASL) versus pseudo-continuous arterial spin labeling (pCASL)

NeuroImage: Clinical, 2014
Background: Arterial spin labeling (ASL) perfusion-weighted imaging (PWI) by magnetic resonance imaging (MRI) has been shown to be useful for identifying asphyxiated newborns at risk of developing brain injury, whether or not therapeutic hypothermia was ...

A potential new role for ASL perfusion imaging: Diagnosis of metronidazole induced encephalopathy – Two companion cases

Radiology Case Reports, 2020
Metronidazole induced encephalopathy (MIE) is a rare condition due to prolonged high dose administration of metronidazole. MIE with corresponding increased perfusion on MRI arterial spin labeling (ASL) of the involved regions of the brain appears not to ...

Arterial spin labeling in neuroimaging

World Journal of Radiology, 2010
Arterial spin labeling (ASL) is a magnetic resonance imaging technique for measuring tissue perfusion using a freely diffusible intrinsic tracer. As compared with other perfusion techniques, ASL offers several advantages and is now available for routine clinical practice in many institutions. Its noninvasive nature and ability to quantitatively measure

Non-contrast quantitative study of brain perfusion changes in multiple sclerosis [PDF]

Digital Diagnostics
BACKGROUND: Non-contrast magnetic resonance perfusion can identify areas of cerebral perfusion changes in patients with multiple sclerosis, even in the absence of focal lesions [1]. This technique offers several advantages, including non-invasiveness [2]

Prematurity and brain perfusion: Arterial spin labeling MRI

NeuroImage: Clinical, 2017
Purpose: Abnormal brain perfusion is a critical mechanism in neonatal brain injury. The aim of the present study was to compare Cerebral Blood Flow (CBF) evaluated with ASL MRI in three groups of neonates: preterms without brain lesions on MRI (PN ...
