Cerebrovascular Reactivity Assessed by Breath-Hold Functional MRI in Patients with Neurological Post-COVID-19 Syndrome-A Pilot Study.

Endothelial dysfunction represents a potential pathomechanism of neurological post-COVID-19 syndrome (PCS). A recent study demonstrated reduced cerebrovascular reactivity (CVR) in patients with PCS. The aim of this pilot study was to prospectively assess CVR in patients with PCS using breath-hold functional MRI (bh-fMRI).

Accelerated diffusion-weighted imaging of the prostate using deep learning image reconstruction: A retrospective comparison with standard diffusion-weighted imaging.

Purpose: Routine multiparametric MRI of the prostate reduces overtreatment and increases sensitivity in the diagnosis of the most common solid cancer in men. However, the capacity of MRI systems is limited. Here we investigate the ability of deep learning image reconstruction to accelerate time consuming diffusion-weighted imaging (DWI) acquisition while maintaining diagnostic image quality.

[Diagnostic delaying factors in hepatic alveolar echinococcosis].

Purpose: The purpose of this study was to analyze the diagnostic workflow of patients with alveolar echinococcosis (AE) and to identify possible diagnosis-delaying factors.

Methods: The number and type of diagnostic procedures of patients diagnosed with alveolar echinococcosis were investigated. The disease history was recorded on the basis of questionnaires, the available findings, and data supplements from the hospital information system (SAP).

Developmental cell death of cortical projection neurons is controlled by a Bcl11a/Bcl6-dependent pathway.

Developmental neuron death plays a pivotal role in refining organization and wiring during neocortex formation. Aberrant regulation of this process results in neurodevelopmental disorders including impaired learning and memory. Underlying molecular pathways are incompletely determined.
