Clinical utility of arterial spin labeling magnetic resonance imaging in the evaluation of the brain

Journal of Medical Physics, 2023
Introduction: Cerebral blood flow (CBF) is essential for studying the brain in both normal and diseased states. Arterial spin labeling (ASL) is a functional magnetic resonance imaging (MRI) technique that uses arterial water as an endogenous tracer to ...

Heme‐NO Dilates Arteries via Mobilization of NO Moieties From an Intracellular NO Store Within Vascular Smooth Muscle Cells

Advanced Science, EarlyView.
Nitrosyl heme emerges as an extracellular nitrodilator that dilates arteries without crossing the cell membrane. Instead, heme‐NO mobilizes NO moieties from a preformed intracellular NO store within vascular smooth muscle, providing both functional and chemical evidence for the NANOS model, revealing a previously unrecognized mechanism of arterial ...

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 ...

Physiopathological implications of abnormal Arterial Spin Labeling perfusion in thrombotic microangiopathy

Thrombosis Update, 2021
Thrombotic microangiopathies are a group of clinical syndromes characterized by microangiopathic hemolytic anemia, thrombocytopenia and end-organ damage, which can compromise the central nervous system.

ZDHHC9‐Mediated Palmitoylation of ACSL4 Drives Ferroptosis in Diabetes Mellitus–Induced Erectile Dysfunction

Advanced Science, EarlyView.
ABSTRACT Diabetes mellitus‐induced erectile dysfunction (DMED) is a highly prevalent complication among diabetic patients; however, its underlying pathogenic mechanisms remain incompletely understood. Metabolic disorder is a hallmark of diabetes, yet its precise contribution to DMED progression is not well defined.

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

CD4+ Tregs Drive Post‐Ischemic Sprouting Angiogenesis via Endothelial YY1/MAML1 Reactivation

Advanced Science, EarlyView.
ABSTRACT Microvascular complications of diabetes are chronic diseases of small vessels. We previously found that CD4+ regulatory T‐cells (Tregs) are markedly reduced in type 2 diabetes (T2D) after ischemic injury in both mice and humans, and that Treg deficiency in immunodeficient mice impairs vascular regeneration.

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

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.
