Combining convolutional attention mechanism and residual deformable Transformer for infarct segmentation from CT scans of acute ischemic stroke patients
ConclusionThe strong correlation between the infarct segmentation obtained via our method and the ground truth allows us to conclude that our method could accurately segment infarcts from NCCT images.

On Hoofs and Zebras – Struma Ovarii
A 75-year-old mother of ten suffering from a urinary tract infection developed macrohematuria and therefore an abdominal ultrasound was performed, followed by a CT scan when an unexpected large pelvic mass was discovered. Past history included hypertension, paroxysmal atrial fibrillation, and remote history of minor stroke (on candesartan, dabigatran, bisoprolol); bilateral chronic lymphedema; and hysterectomy due to prolapse at the age of 40. Imaging revealed nephrolithiasis and a prominent left adnexal mass suspected as ovarian cancer.

Incidental findings on FDG-PET/CT in large vessel vasculitis
This study aims to determine the number and type of incidental findings detected on positron emission tomography (PET)/CT in a cohort of patients with large vessel vasculitis (LVV). Reports from PET/CT studies along with the medical charts of a cohort of patients with LVV from a Rheumatology clinic in Edmonton, Alberta, Canada, were retrospectively reviewed. Incidental findings from PET/CT, along with follow-up studies and their diagnosis were documented. The data was analyzed with descriptive statistics. The disease activity of 40 patients, with an average age of 65.8 years, was investigated using PET/CT. A statisticall...

Scientists Are Just Beginning to Understand COVID-19 ’ s Effect On the Brain
Early in the COVID-19 pandemic, doctors started to notice something striking. For what was originally described as a respiratory virus, SARS-CoV-2 seemed to have a strong effect on the brain, causing everything from loss of taste and smell and brain fog to, in serious cases, stroke.
NYU Langone Health, a New York city research hospital, started collating those anecdotes in hopes of better understanding how the virus affects the brain and nervous system. Years later, the project has morphed from focusing solely on acute symptoms to also tracking the long-term neurologic issues that some people with Long COVID experience, sa...

White Matter Microstructural Alterations over the Year after Acute Ischemic Stroke in Patients with Baseline Impaired Cognitive Functions
CONCLUSION: The finding suggests that the patients with baseline impaired cognitive functions still have WM microstructural damages at 1 year poststroke, even if their cognitive function has improved or returned to normal. Cautions should be taken against the possible negative impact of these changes on long-term cognition.PMID:37456365 | PMC:PMC10348854 | DOI:10.1155/2023/6762225
