Anatomy imaging and hemodynamics research on the cerebral vein and venous sinus among individuals without cranial sinus and jugular vein diseases

Frontiers in Neuroscience, 2022
In recent years, imaging technology has allowed the visualization of intracranial and extracranial vascular systems. However, compared with the cerebral arterial system, the relative lack of image information, individual differences in the anatomy of the

Research progress on the relationship between cerebral venous system diseases and cerebral autoregulation

Chinese Journal of Contemporary Neurology and Neurosurgery, 2022
Cerebral autoregulation (CA) refers to the ability of the brain to maintain a relatively constant cerebral blood flow (CBF) when arterial blood pressure fluctuates within a wide range.

Use of real-time phase-contrast MRI to quantify the effect of spontaneous breathing on the cerebral arteries

NeuroImage, 2022
Quantification of the effect of breathing on the cerebral circulation provides a better mechanistic understanding of the brain's circulatory system and is important in the early diagnosis of certain neurological diseases. However, conventional cine phase-
