Coronavirus disease 2019 has spread to every inhabited continent in the world. So far, plain radiography and computed tomography have been the mainstay of imaging methods used. The present analytical paper on the role of point-of-care lung ultrasound in this pandemic examines its diagnostic accuracy, clinical utility, and physical practicality in the intensive care unit.

Coronavirus disease 2019 (COVID-19) has spread fast and extensively around the world, with significant mortality and morbidity. As this is a respiratory infection, chest radiography and computed tomography (CT) are important imaging techniques in the work-up of this disease. Given its highly infectious nature, cross-infection within the healthcare setting and radiology departments needs to be addressed actively and prevented. We describe the response of radiology departments in Singapore to this pandemic, in terms of diagnosis, re-configuration of the department, re-organisation and segregation of staff, infection control, managerial, and leadership issues.

The incidence of cerebral venous thrombosis (CVT) is increasing due to the widespread use of computed tomography (CT) and magnetic resonance imaging (MRI) for investigating patients with acute headaches and new onset of seizures. Alternatively referred to as cerebral venous sinus thrombosis (CVST) or dural venous sinus thrombosis (DVST), the terms encompass a broad spectrum of neurological pathologies. These include dural venous sinus thrombosis, cortical vein thrombosis, cavernous sinus thrombosis, venous infarction/haemorrhage, and the rare sequelae of intracranial hypertension or dural arteriovenous fistula. ⋯ MRI or MRI venography (MRV) are powerful techniques, provided the radiologist is aware of critical diagnostic pitfalls. In selected cases, cerebral digital subtraction angiography (DSA) can facilitate both diagnosis and anticoagulant/transcatheter thrombolytic therapy improving clinical outcome. This article will outline the condition, highlighting cerebral venous anatomy, diagnostic techniques, and pitfalls pertinent to all practising radiologists.
