Artificial Intelligence in the Time of COVID-19

Tuesday, June 2
Broadcasted Live and Online 2:00–3:00 pm, Eastern Time

Artificial intelligence algorithms applied to COVID-19 confirmed patients or subjects under investigation offer the potential to develop a more accurate automated approach for early detection and prognostication using the combination of clinical and imaging data. At the moment, several AI solutions are being developed to be applied in different stages of the COVID-19 diagnostic workflow, from diagnosis to prognosis. In this webinar, we will present the actual status of AI applications in COVID-19 imaging, and we will critically appraise the available AI solutions.

AJR Podcast

Although the clinical symptoms of pediatric COVID-19 pneumonia may be non-specific, some characteristic imaging findings have emerged or are currently emerging. This podcast focuses on chest imaging in pediatric patients with COVID-19 infection including characteristic chest imaging findings and imaging recommendations.

Comparing CT and RT-PCR Viral Nucleic Acid Testing

Multiple studies suggest CT should be a primary diagnostic tool for coronavirus disease (COVID-19) because they reported sensitivities with CT far superior to that of reverse transcriptase polymerase chain reaction (RT-PCR) testing. This review aimed to assess these reports and found chest CT to have a clinical utility that is limited, particularly for patients who show no symptoms and patients who are screened early in disease progression.

Can Chest CT Features Distinguish Patients With Negative From Those With Positive Initial RT-PCR Results for Coronavirus Disease COVID-19?

The purpose of this open access study was to explore the value of CT in the diagnosis of coronavirus disease (COVID-19) pneumonia, especially for patients who have negative initial results of reverse transcription–polymerase chain reaction (RT-PCR) testing.

Wuhan CT Scans Reliable for Coronavirus Diagnosis, Limited for Differentiation

An article by radiologists from Wuhan, China concluded that chest CT had a low rate of misdiagnosis of COVID-19 (3.9%, 2/51) and could help standardize imaging features and rules of transformation for rapid diagnosis; however, CT remains limited for the identification of specific viruses and distinguishing between viruses.
