AI Article Synopsis
- Diffusion-weighted imaging (DWI) is mainly used to evaluate brain tissue, especially during acute strokes.* -
- DWI's applications also cover extra-axial structures in the head and neck, providing insights into various disorders beyond just the brain.* -
- The article emphasizes the importance of thoroughly examining both intra- and extra-axial structures on DWI for a comprehensive assessment.*
Article Abstract
Diffusion-weighted imaging (DWI) has a central role in the assessment of the brain parenchyma, particularly in the context of acute stroke. However, the applications of DWI extend far beyond the brain parenchyma and include the assessment of the extra-axial structures of the head and neck that are included in routine brain imaging. In this pictorial review, the added-value of DWI over other conventional sequences is illustrated through discussion of a broad range of disorders affecting the vasculature, skull, orbits, nasal cavity and salivary glands. This article highlights the requirement for all structures, both intra- and extra-axial, to be carefully reviewed on DWI.

Brain macrophages in vascular health and dysfunction.

Diverse macrophage populations inhabit the rodent and human central nervous system (CNS), including microglia in the parenchyma and border-associated macrophages (BAMs) in the meninges, choroid plexus, and perivascular spaces. These innate immune phagocytes are essential in brain development and maintaining homeostasis, but they also play diverse roles in neurological diseases. In this review, we highlight the emerging roles of CNS macrophages in regulating vascular function in health and disease.

Objective: Periventricular anastomosis (PA), a recently recognized cause of hemorrhage in moyamoya disease, is reducible after bypass surgery. The timing of the reduction, however, remains poorly understood. The objectives of the present study were to demonstrate radiological reduction of PA occurring within 48 hours after surgery and to identify factors associated with reduction.

The deposition of aggregated amyloid β (Aβ) is considered as a key factor for Alzheimer's Disease (AD). Previously, we demonstrated that a carboxylated Zn-phthalocyanine (ZnPc) inhibits Aβ fibril formation, consequently protects neurons in culture. This study evaluated the effects of ZnPc on pathological changes in an AD mouse model (J20).

Introduction: Efficacy of deep brain stimulation (DBS) is established for several movement and psychiatric disorders. However, the mechanism of action and local tissue changes are incompletely described. We describe neurohistopathological findings of 9 patients who underwent DBS for parkinsonism and performed a systematic literature review on postmortem pathologic reports post-DBS.

Background And Objectives: Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) syndrome is a maternally inherited mitochondrial disorder that mostly affects the central nervous system and skeletal muscle. This study provides a comprehensive summary of the clinical symptoms, multisystemic pathogenesis, and genetic characteristics of MELAS syndrome. The aim was to improve comprehension of clinical practice and gain a deeper understanding of the latest pathophysiological theories.
