Multicenter Study Comparative Study
Risk of acute pulmonary embolism in COVID-19 pneumonia compared to community-acquired pneumonia: a retrospective case-control study.
To compare the incidence of pulmonary embolism (PE) in COVID-19 pneumonia and non-COVID-19-related community-acquired pneumonia (CAP) in hospitalised patients. ⋯ The odds of developing PE in hospitalised patients with COVID-19 pneumonia are three-times higher than in those with CAP. The results provide a quantitative assessment of the risk of PE in COVID-19 pneumonia, a condition new to healthcare, compared to other forms of pneumonia with a well-established scientific basis.

To evaluate whether portable chest radiography (CXR) scores are associated with coronavirus disease 2019 (COVID-19) status and various clinical outcomes. ⋯ Initial CXR scores have prognostic value and are associated with COVID-19 positivity, ICU admission, and mechanical ventilation.
-
To evaluate the lung function of coronavirus disease 2019 (COVID-19) patients using oxygen-enhanced (OE) ultrashort echo time (UTE) MRI. ⋯ OE-UTE-MRI could serve as a promising method for the assessment of lung function or treatment management of COVID-19 patients.

Observational Study
COVID-19-related intracranial imaging findings: a large single-centre experience.
To describe the neuroradiological changes in patients with coronavirus disease 2019 (COVID-19). ⋯ Various imaging patterns on MRI were observed including acute haemorrhagic necrotising encephalopathy, white matter hyperintensities, hypoxic-ischaemic changes, ADEM-like changes, and stroke. Microhaemorrhages were the most common findings. Prolonged hypoxaemia, consumption coagulopathy, and endothelial disruption are the likely pathological drivers and reflect disease severity in this patient cohort.

To investigate the value of new diffusion-weighted imaging applications in the characterisation of suspicious breast lesions with emphasis on diffusion tensor imaging (DTI) and fibre tractography (FT). ⋯ DTI and FT are new applications of DWI. They show promising results for the evaluation of suspicious breast masses and can distinguish between benign and malignant breast lesions with statistical significance approaching contrast-enhanced MRI, which is considered the imaging reference standard for characterising breast lesions.
