How does COVID-19 differ from other coronaviruses?

February 28, 2020 -- Although the imaging features of the novel coronavirus (COVID-19) overlap with those of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), there are differences on imaging exams that set the virus apart -- particularly that it tends to manifest in both lungs rather than one, according to a February 28 study in the American Journal of Roentgenology.

Recovered COVID-19 patients may still test positive

February 28, 2020 -- Patients who have apparently recovered from the novel coronavirus disease (COVID-19) may later prove positive for it when evaluated with reverse transcription polymerase chain reaction testing -- indicating they may still be carriers of the virus, according to a research letter published online February 27 in JAMA.

FDA recognizes AI-based image acquisition software

February 28, 2020 -- The U.S. Food and Drug Administration (FDA) created a new regulatory classification for artificial intelligence (AI)-guided image acquisition and optimization software earlier in February when it cleared a new AI-based echocardiography acquisition application. An FDA representative detailed the new rule in a talk Wednesday at a public workshop. Discuss

CT CAC predicts risk of death in smokers

February 28, 2020 -- The presence of coronary artery calcium (CAC) on CT scans was associated with an increased risk of death from cardiovascular diseases, cancer, and all causes combined -- including for a subset of smokers eligible for CT lung cancer screening -- in a study published in the February issue of Atherosclerosis.

Older endurance athletes have risk of enlarged aorta

February 28, 2020 -- Older endurance athletes may be prone to heart conditions with a relatively high risk of death. Echocardiographic imaging helped identify an enlarged aorta in 25% of older athletes in a new study, published on February 26 in JAMA Cardiology. Discuss

What do radiologists need to know about the coronavirus?

February 27, 2020 -- To help radiologists stay up to date on the ever-evolving coronavirus epidemic, an expert panel gave the lowdown on the current understanding of the coronavirus disease and highlighted the points most pertinent to radiologists in an article published online on February 27 in Radiology.

MRI finds gender differences even in healthy hearts

February 27, 2020 -- An investigational 4D flow MRI sequence has helped researchers confirm different blood flow characteristics in the hearts of young, healthy men and women. The findings could help clinicians set benchmarks for comparisons with unhealthy patients, according to a study published February 27 in Radiology: Cardiothoracic Imaging. Discuss

Ultrasound performance mixed in breast cancer survivors

February 27, 2020 -- Supplemental screening ultrasound shows a mixed performance in women with a personal history of breast cancer, with lower sensitivity and a higher interval cancer rate. But the modality also had higher specificity, according to a study published online February 25 in Radiology. Discuss

What issues are hindering AI's utility in radiology?

February 26, 2020 -- Artificial intelligence (AI) technology has much potential in radiology, but several key issues are limiting its current clinical utility, according to a presentation on Tuesday at a public workshop held by the U.S. Food and Drug Administration on the evolving role of AI in radiology.
