AI software can cut screening mammography workload
August 26, 2020 -- Swedish researchers found that artificial intelligence (AI)-based computer-aided detection software cut radiologists' screening mammogram workload by more than half. It also could catch more interval and future screening-detected cancers, according to a study published online August 24 in the Lancet: Digital Health.  Discuss
Augmented reality enhances medical student training
August 25, 2020 -- Augmented reality (AR) technology and 3D CT holograms can significantly improve recall of head and neck anatomy in first-year medical students, yielding better performance than viewing the holograms on traditional laptop displays, according to research published online August 20 in Academic Radiology.  Discuss
3D printing can help in planning complex CHD surgeries
August 24, 2020 -- 3D printing can influence strategy changes and improve surgical confidence when planning surgeries for complex cases of congenital heart disease (CHD), according to research published online in JACC: Cardiovascular Imaging.  Discuss
AI algorithm may be generalizable for spotting COVID-19
August 21, 2020 -- An artificial intelligence (AI) algorithm trained on a large, multinational dataset can be highly accurate for identifying COVID-19 pneumonia on chest CT scans, according to research published online August 14 in Nature Communications. It can also be highly specific for non-COVID-19-related pneumonias.  Discuss
3D CT models can help assess COVID-19 lung damage
August 20, 2020 -- Can advanced visualization techniques used to research the lungs of reptiles and birds also help diagnose COVID-19 in humans? Applying methods from evolutionary anatomy research, a Louisiana State University team has created 3D digitally segmented models that demonstrate the extent and distribution of the disease.  Discuss
MRI is a good alternative to CT for COVID-19 diagnosis
August 19, 2020 -- Chest CT has been widely used to diagnose COVID-19 disease, but MRI offers an attractive alternative that doesn't require radiation, according to a study published August 15 in Academic Radiology.  Discuss
ABR Core Exams to be held over 3 days in 2021
August 18, 2020 -- The American Board of Radiology (ABR) said that remote administrations of its Diagnostic Radiology and Interventional Radiology/Diagnostic Radiology Core Exams in 2021 will now be held over three days.  Discuss
What will be the killer apps for AI in MRI?
August 10, 2020 -- Artificial intelligence (AI) shows potential to have a substantial clinical impact in a wide range of applications in MRI, but image interpretation isn't on the immediate radar, according to an August 8 presentation at the Society for MR Radiographers & Technologists meeting.  Discuss
Augmented reality can control MR scanners
August 8, 2020 -- Augmented reality can provide an alternative to traditional MR console software for controlling the scanner and viewing images, according to research presented at this week's virtual conference and exhibition of the International Society for Magnetic Resonance in Medicine.  Discuss
Radiology practices cut costs in response to COVID-19
August 6, 2020 -- Faced with sharply lower imaging volumes in the onset of the COVID-19 pandemic, most radiology practices in the U.S. were forced to adopt cost-cutting measures such as reducing headcount, salaries, and incentive payments, according to research published online August 4 in the Journal of the American College of Radiology.  Discuss
