    Abstract In the present case report, a 50-year-old female presented with hemiparesis and blurred vision and was subsequently diagnosed with posterior reversible encephalopathy syndrome (PRES) associated with coronavirus disease 2019 (COVID-19). Magnetic resonance imaging revealed cortico-subcortical edema with hyperintensities bilaterally in the frontoparietal and bi-occipital regions. Although PRES is a neurotoxic disorder that typically affects white matter of the brain and often is associated with hypertension, renal failure, and autoimmune disorders, recent studies have suggested that COVID-19 increases the risk of PRES. This case report presents a unique instance of COVID-19-related PRES. Unlike most previously reported cases occurring during the acute phase of severe COVID-19, our patient experienced PRES during the recovery phase with mild initial symptoms, such as fatigue and mild fever. The article discusses the pathophysiology of PRES, the potential mechanisms by which COVID-19 leads to PRES, and the treatment and outcome of the patient.

    Abstract Purpose To compare the image quality and diagnostic capability in detecting malignant liver tumors of low-dose CT (LDCT, 33% dose) with deep learning-based denoising (DLD) and standard-dose CT (SDCT, 100% dose) with model-based iterative reconstruction (MBIR). Materials and Methods In this prospective, multicenter, noninferiority study, individuals referred for liver CT scans were enrolled from three tertiary referral hospitals between February 2021 and August 2022. All liver CT scans were conducted using a dual-source scanner with the dose split into tubes A (67% dose) and B (33% dose). Blended images from tubes A and B were created using MBIR to produce SDCT images, whereas LDCT images used data from tube B and were reconstructed with DLD. The noise in liver images was measured and compared between imaging techniques. The diagnostic performance of each technique in detecting malignant liver tumors was evaluated by three independent radiologists using jackknife alternative free-response receiver operating characteristic analysis. Noninferiority of LDCT compared with SDCT was declared when the lower limit of the 95% CI for the difference in figure of merit (FOM) was greater than -0.10. Results A total of 296 participants (196 men, 100 women; mean age, 60.5 years ± 13.3 [SD]) were included. The mean noise level in the liver was significantly lower for LDCT (10.1) compared with SDCT (10.7) (

    Title translation Patient-centered vs. employee-centered radiology : Does this pose a conflict?
    Abstract Background: Patient-centered radiology and employee-centered radiology are being increasingly discussed as an extension of the established structure- and process-oriented management perspective. Concerning potential conflicts, it is unclear if and how these approaches should best be implemented in a radiology department.
    Objective: The aim of this narrative review is to identify and critically correlate underlying characteristics of patient-centered and employee-centered approaches including their similarities, conflicts, and synergies as applicable to the radiological work environment.
    Materials and methods: Based on a literature search using PubMed, Scopus, Web of Science, and Google Scholar, the current body of knowledge regarding patient- and employee-centered radiology is presented.
    Results: Patient- and employee-centered radiology focus on the individual needs of patients and employees, respectively, and promise to improve patient satisfaction, healthcare outcomes, and organizational performance. Conflicts result from an increased organizational complexity and the concurrent utilization of limited resources, such as time, money, and staff. Overall, however, synergies outweigh the potential conflicts.
    Conclusions: Successful implementation of patient- and employee-centered approaches in radiology requires a human-centered leadership approach and an overarching strategy with the execution of specific interventions in the processes. We provide specific recommendations to this effect.
