COVID-19 patients face higher risk of barotrauma
July 7, 2020 -- Patients with COVID-19 who require invasive mechanical ventilation are more likely to experience barotrauma such as pneumothorax and pneumomediastinum than those without the disease, according to research published online July 2 in Radiology. And younger patients with COVID-19 were particularly at risk for these serious events.  Discuss
Can radiomics improve CT lung cancer screening?
July 7, 2020 -- Two radiomics features on low-dose CT (LDCT) exams in lung cancer screening can be used to identify early-stage lung cancer patients who may be at higher risk for poor survival outcomes, potentially enabling earlier interventions, according to research published online June 29 in Scientific Reports.  Discuss
ACR, RSNA calls on FDA to hold off on autonomous AI
July 1, 2020 -- Autonomous artificial intelligence (AI) algorithms aren't close to being safe enough to replace radiologists, and the U.S. Food and Drug Administration (FDA) should hold off for now on developing regulatory pathways for autonomous AI in radiology, according to the American College of Radiology (ACR) and the RSNA.  Discuss
AI algorithm can help in incidental detection of PE
June 30, 2020 -- An artificial intelligence (AI) algorithm can highlight incidental cases of pulmonary embolism (PE) on contrast-enhanced chest CT exams that were performed for reasons other than to detect PE, according to a presentation at the recent online annual conference of the Society for Imaging Informatics in Medicine.  Discuss
SIIM 2020: The future is now for 3D imaging
June 26, 2020 -- The future is now for 3D imaging technologies such as cinematic rendering, 3D printing, simulation training, virtual reality, and augmented reality, according to a June 26 presentation at the virtual annual meeting of the Society for Imaging Informatics in Medicine (SIIM).  Discuss
SIIM 2020: Human element shouldn't be neglected with AI
June 25, 2020 -- Sure, artificial intelligence (AI) in radiology is cool. But it's not enough to show results in a lab; the technology's real-world impact on efficacy and efficiency also needs to be evaluated, according to a June 25 talk at the virtual annual meeting of the Society for Imaging Informatics in Medicine (SIIM).  Discuss
SIIM 2020: How to create robust radiology AI algorithms
June 25, 2020 -- It's not easy to develop radiology artificial intelligence (AI) algorithms that don't just perform well on data that are similar to what they are trained on. But there are ways to help improve AI robustness, according to June 24 talks at the virtual annual meeting of the Society for Imaging Informatics in Medicine (SIIM).  Discuss
4D Flow MRI is feasible during exercise
June 19, 2020 -- Cardiac 4D flow MRI can quantify blood flow in the ascending aorta and main pulmonary artery during strenuous exercise, offering potential as a useful modality for evaluating right-sided heart dysfunction, according to research published online June 18 in Radiology: Cardiothoracic Imaging.  Discuss
5 ways rads can use social media to shift AI narrative
June 19, 2020 -- Misleading commentary and incorrect information on social media regarding the impact of artificial intelligence (AI) on radiology can significantly impact how the specialty is perceived, and it's time for radiologists to reshape the conversation, according to an article published online June 15 in Clinical Imaging.  Discuss
AI algorithm detects appendicitis on CT exams in ER
June 18, 2020 -- South Korean researchers developed an artificial intelligence (AI) algorithm that was highly accurate and generalizable for detecting acute appendicitis on CT exams in emergency room (ER) patients. The algorithm could, if necessary, potentially fill in for a radiologist, according to research published online June 12 in Scientific Reports.  Discuss
