Building a Synthetic Vascular Model: Evaluation in an Intracranial Aneurysms Detection Scenario [PDF]

We hereby present a full synthetic model, able to mimic the various constituents of the cerebral vascular tree, including the cerebral arteries, bifurcations and intracranial aneurysms. This model intends to provide a substantial dataset of brain arteries which could be used by a 3D convolutional neural network to efficiently detect Intra-Cranial ...

Neonatal Cholestasis Progressing to a Multisystem Syndrome With Liver Cirrhosis in Two Siblings With FARSA Deficiency: An Evolving Hepatological Phenotype

JIMD Reports, Volume 66, Issue 3, May 2025.
ABSTRACT Biallelic variants in FARSA or FARSB are associated with reduced cytoplasmic phenylalanyl‐tRNA synthetase (FARS1) activity and underlie a multisystem syndrome characterized by growth limitation, developmental delay, brain calcifications, interstitial lung disease (ILD), and liver involvement.

Loss Ensembles for Extremely Imbalanced Segmentation [PDF]

arXiv, 2020
This short paper briefly presents our methodology details of automatic intracranial aneurysms segmentation from brain MR scans. We use ensembles of multiple models trained from different loss functions. Our method ranked first place in the ADAM challenge segmentation task. The code and trained models are publicly available at https://github.com/JunMa11/

Interleaved flow‐sensitive dephasing (iFSD): Toward enhanced blood flow suppression and preserved T1 weighting and overall signals in 3D TSE‐based neuroimaging

Magnetic Resonance in Medicine, Volume 93, Issue 5, Page 1911-1923, May 2025.
Abstract Purpose To develop and validate a 3D turbo spin‐echo (TSE)–compatible approach to enhancing black‐blood (BB) effects while preserving T1 weighting and overall SNR. Methods Following the excitation RF pulse, a 180° RF pulse sandwiched by a pair of flow‐sensitive dephasing (FSD) gradient pulses in the phase‐ (y) and partition‐encoding (z ...

Cerebrovascular Involvement in Systemic Sclerosis

ACR Open Rheumatology, Volume 7, Issue 4, April 2025.
Systemic sclerosis (SSc) is a chronic autoimmune rheumatic disease characterized by vascular damage, immune system dysregulation and fibrosis. The hallmark features include microvascular alterations and progressive tissue fibrosis, affecting skin, internal organs as well central and peripheral nervous system, adding to the disease's complexity and ...

G‐Protein‐Coupled Receptor 84 Aggravates Early Brain Injury via Microglial NLRP3‐ASC Inflammasome After Subarachnoid Hemorrhage

Brain and Behavior, Volume 15, Issue 4, April 2025.
GPR84 in microglia is upregulated, activates NLRP3 inflammasomes and promotes IL‐1β secretion, which is revised by GPR84 inhibition. ABSTRACT Background Subarachnoid hemorrhage (SAH) is one of the most devastating hemorrhagic strokes. SAH causes neuroinflammation and leads to both early brain injury and delayed brain injury.

Treatment of thoracic outlet syndrome to relieve chronic migraine

Clinical Anatomy, Volume 38, Issue 3, Page 314-323, April 2025.
Abstract Prior case reports have suggested that treating thoracic outlet syndrome (TOS) may relieve intractable migraine headaches, but there has been no case series large enough to show when underlying TOS should be suspected as a contributor to migraine burden.

A Nonlinear Mechanics-based Virtual Coiling Method For Intracranial Aneurysm [PDF]

SB3C (2019), 2020
Enodvascular coils treat intracranial aneurysms (IAs) by causing them to occlude by thrombosis. Ideally, coiled IAs eventually occlude in the long-term. However, 20.8% are found incompletely occluded at treatment follow-up. Computer simulations of coiling and its effect on aneurysmal flow could help clinicians predict treatment outcomes a priori, but ...
