ABSTRACT Background and Aims Artificial intelligence (AI) is increasingly being integrated into neurosurgical practice, offering capabilities in diagnostic imaging, surgical planning, and outcome prediction. However, the “black box” nature of many AI systems generating recommendations without a transparent rationale poses fundamental challenges to ...

ABSTRACT Background and Aims Major adverse cardiac and cerebrovascular events (MACCE) are significant complications following percutaneous coronary intervention (PCI). Identifying the predictors of these events can aid in improving outcomes, especially in specific populations such as the Iranian cohort.

This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Cerebral Blood Transit in Sickle Cell Anemia
ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...

This study investigated whether using a larger image matrix (1024 × 1024 pixels instead of 512 × 512) improves the visibility of tiny brain arteries on CT scans performed with standard 64‐slice scanners. While physical image quality measurements remained unchanged, the larger matrix provided finer digital sampling of blood vessel structures, resulting ...

Migraine: Epidemiology, Risk Factors, Pathophysiology, and Treatment
Migraine is a highly prevalent, female‐predominant, and disabling brain disorder shaped by genetic susceptibility, hormonal influences, modifiable attack factors, and comorbidity‐related progression. This review integrates current evidence on migraine epidemiology, phase‐specific neurovascular and neuroglial mechanisms, including CGRP signaling and ...

Neurocardiology: Brain–Heart Interactions in the Heart
The heart and brain maintain systemic homeostasis through bidirectional communication involving neural, biochemical, and mechanical pathways. Dysregulation of these pathways contributes to a spectrum of conditions involving heart–brain interactions, including Takotsubo syndrome, the epileptic heart, stroke–heart syndrome, heart failure, cardiac ...

The clinical manifestations of PFO. Although the majority of PFOs are benign and asymptomatic, they can present with a variety of clinical manifestations, or coexisting with other diseases and aggravating their symptoms, including cerebral diseases (such as CS, epilepsy, TIA, or migraine), systemic embolism (such as embolism in renal artery, coronary ...

DynaTOF: Time‐Resolved Noncontrast Cerebral MR Angiography Using Spatially Modulated RF Saturation
ABSTRACT Purpose To develop a time‐resolved extension of three‐dimensional time‐of‐flight MR angiography, termed Dynamic TOF (DynaTOF), that exploits intrinsic RF saturation behavior to enable noncontrast visualization of cerebrovascular hemodynamics.
