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
AI analyzes likelihood, extent of COVID-19 on chest CT
August 6, 2020 -- A freely available artificial intelligence (AI) algorithm can yield comparable diagnostic performance to radiologists for assessing the likelihood and severity of COVID-19 on noncontrast chest CT exams in patients suspected of having the disease, according to research published online in Radiology on July 30.  Discuss
Russian scientists develop breast MRI device
August 5, 2020 -- A group of Russian scientists have developed a device that can enable existing MRI scanners to perform breast MRI without the need for specialized breast coils. They shared their results in research published online July 31 in Nature Communications.  Discuss
Pediatric EDs using more ultrasound, MRI instead of CT
August 3, 2020 -- Although pediatric emergency departments (EDs) performed fewer CT exams between 2009 and 2018, their utilization of advanced imaging increased overall due to expanded use of MRI and ultrasound exams, according to research published online August 3 in JAMA Pediatrics.  Discuss
COVID-19 likely more than a respiratory illness in kids
August 3, 2020 -- A disease associated with COVID-19 that causes multiple organ failure in children presents imaging findings that are different than a typical acute infection, indicating that COVID-19 is likely far more than a respiratory illness in kids, according to an article published online July 30 in Radiology: Cardiothoracic Imaging.  Discuss
Federated learning yields high-quality AI model
July 31, 2020 -- Federated learning -- an approach to training deep-learning models that incorporates data from other sites without sharing the actual data -- can protect patient privacy and enable more-generalizable radiology artificial intelligence (AI) algorithms, according to research published online July 28 in Scientific Reports.  Discuss
Cancer screenings drop precipitously due to COVID-19
July 28, 2020 -- The number of screening exams for colorectal and breast cancer performed at 20 U.S. hospitals dropped by nearly 90% in April due to the COVID-19 pandemic, according to research published online July 27 in JCO Clinical Cancer Informatics.  Discuss
CT radiomics can predict COVID-19 pneumonia outcomes
July 28, 2020 -- Radiomics features on noncontrast-enhanced chest CT exams can help to identify which patients with COVID-19 pneumonia will need to be admitted to the intensive care unit. They can also predict patient outcomes, according to research published online July 23 in Radiology: Cardiothoracic Imaging.  Discuss
