CT Reconstruction Levels Affect Automated and Reader-Based ASPECTS Ratings in Acute Ischemic Stroke.
We investigated whether automated and reader-based ASPECTS in acute stroke patients are affected by different CT image reconstruction algorithms. ⋯ CT image postprocessing affects either automated or human ASPECTS in acute stroke patients. This effect was most pronounced in the less experienced readers, while the software had the most robust performance.

To characterize the relationship between computed tomography angiography (CTA) imaging characteristics of carotid artery and the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) score. ⋯ There is some concordance but not a perfect overlap between the 10-year ASCVD risk scores calculated from clinical and blood assessment and carotid artery imaging findings.

Oxaliplatin-induced neuropathy is a major dose limiting side effect of the highly effective combination chemotherapy with oxaliplatin, irinotecan, and 5-fluorouracil (FOLFIRINOX) in patients with metastastic pancreatic cancer. We present the first longitudinal sonographical-electrophysiological study on oxaliplatin-induced neuropathy. ⋯ Oxaliplatin-induced neuropathy is characterized by an axonal length-dependent nerve affection presenting with a combination of sonographical and electrophysiological alterations.

Optic nerve sheath diameter (ONSD) is used for the estimation of intracranial pressure (ICP). But there are still doubts about the quality of the images and the lateral resolution. Our aim is to investigate the system suitability and best lateral resolution of different ultrasound systems for acoustic ONSD measurement. ⋯ According to our study, both systems are suitable for ultrasound OSND measurement.

Degeneration of gray matter and subcortical structures after ischemic stroke has been well described. However, little is known about white matter degeneration after stroke. It is unclear whether white matter degeneration occurs throughout the whole brain, or whether patterns of degeneration occur more in specific brain areas. ⋯ White matter changes after stroke may be localized rather than a global phenomenon.
