How helpful is CTA for assessing coronary disease risk?
June 4, 2020 -- Adding coronary CT angiography (CTA) to exercise electrocardiography (ECG) testing could be an effective way to predict a patient's five-year risk of coronary disease compared to ECG alone, according to a study published June 3 in JAMA Cardiology.  Discuss
What's the best way to image COVID-19?
June 3, 2020 -- Researchers from Mount Sinai Hospital in New York City have released an overview of imaging modalities used to diagnose and manage COVID-19 pneumonia, trends to watch in artificial intelligence, and a description of nonchest complications from the disease. The review was published June 1 in Radiology: Cardiothoracic Imaging.  Discuss
AI boosts assessment of cancer treatment response
June 3, 2020 -- Artificial intelligence (AI) software can significantly enhance assessment of cancer treatment response on serial CT exams by reducing errors, speeding up interpretations, and decreasing interobserver variability, according to research presented May 29 at the online American Society of Clinical Oncology meeting.  Discuss
AI can aid radiologists in detecting pancreatic cancer
June 1, 2020 -- An artificial intelligence (AI) algorithm helped radiologists from Taiwan improve their performance in detecting pancreatic cancer on CT exams, demonstrating strong performance across a range of ethnicities, according to research published online May 26 in Lancet Digital Health.  Discuss
COVID-19 CT findings often negative in children
May 29, 2020 -- More than three-quarters of chest CT findings in children with laboratory-confirmed COVID-19 disease are negative, according to a study published May 28 in the American Journal of Roentgenology.  Discuss
Isolation bag could block COVID-19 infection on CT
May 28, 2020 -- A simple patient isolation bag made of hypoallergenic plastic polymer could block COVID-19 infection in the CT suite -- and also improve workflow in radiology departments, according to a study published May 25 in Academic Radiology.  Discuss

May 27, 2020 -- Quantitative computer-aided analysis of chest CT scans can help clinicians predict COVID-19 outcomes in hospitalized patients by providing information on a new metric: compromised lung volume, according to a preprint article published May 23 on Research Square.  Discuss
COVID-19 neuro findings marked by mental status, stroke
May 26, 2020 -- Neuroimaging features of hospitalized COVID-19 patients can vary, but they are dominated by altered mental status and acute ischemic stroke, according to research published May 21 in Radiology.  Discuss
Conebeam CT aids removal of rare ectopic molar in maxillary sinus
May 26, 2020 -- Conebeam CT helped clinicians remove an ectopic third molar and an infected cyst from a patient's maxillary sinus, which is a rare site for a tooth to erupt, according to a recent case report published on the open-access platform F1000Research.  Discuss
