Arterial spin labeling in neuroradiology

, 2023
Neurološke bolesti danas predstavljaju važan medicinski i javnozdravstveni problem. Označavanje arterijskog spina je relativno nova, neinvazivna tehnika za mjerenje cerebralnog protoka u magnetskoj rezonanciji, koja daje informacije o perfuziji mozga ...

The progress of arterial spin labeling

Zhongguo aizheng zazhi, 2013
As a kind of non-invasive functional magnetic resonance imaging (fMRI) techniques, arterial spin labeling (ASL) takes full advantage of arterial blood as an endogenous tracer to track changes of blood flow caused by lesions and to obtain the ...

Arterial spin labeling magnetic resonance imaging quantifies tissue perfusion around foot ulcers

Journal of Vascular Surgery Cases and Innovative Techniques, 2022
Objective: Tools that quantify tissue perfusion of the foot are deficient, contributing to the uncertainty in predicting ulcer healing potential.

Applications of arterial spin labeled MRI in the brain [PDF]

Journal of Magnetic Resonance Imaging, 2012
AbstractPerfusion provides oxygen and nutrients to tissues and is closely tied to tissue function while disorders of perfusion are major sources of medical morbidity and mortality. It has been almost two decades since the use of arterial spin labeling (ASL) for noninvasive perfusion imaging was first reported.

Hadamard Encoded Arterial Spin Labeling

, 2021
Creating images of the transit delay from the labeling location to image tissue can aid the optimization and quantification of arterial spin labeling (ASL) perfusion measurements and may provide diagnostic information independent of perfusion ...

Arterial spin labeling assessment of myometrial perfusion changes in patients with uterine fibroid and its impact on fertility

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Fibroids are the most common uterine tumor in the reproductive age group. These tumors although benign, their relation to infertility is still controversial. The purpose of this study is to assess the fibroid impact on fertility using arterial

Arterial Spin-Labeling in the Assessment of Pediatric Nontraumatic Orbital Lesions

, 2023
International audienceBenign and malignant pediatric orbital lesions can sometimes have overlapping features on conventional MR imaging sequences. MR imaging of 27 children was retrospectively reviewed to describe the signal of some common pediatric ...

Can magnetic resonance imaging predict preoperative consistency and vascularity of intracranial meningioma?

The Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background Meningiomas are considered the most common primary intracranial neoplasms. The surgical resection is the main curative therapy. Evaluation of meningioma consistency and vascularity is important before surgery to be aware about the difficulties

Multidelay Arterial Spin-Labeling MRI in Neonates and Infants: Cerebral Perfusion Changes during Brain Maturation [PDF]

, 2018
BACKGROUND AND PURPOSE: Arterial spin-labeling with multiple postlabeling delays can correct transit times. We tried to evaluate CBF in neonates and infants using multidelay arterial spin-labeling.
