Contrast-enhanced mammo can play pivotal diagnostic role
December 2, 2020 -- Contrast-enhanced spectral mammography (CESM) can play a pivotal role in diagnosing some types of breast cancer, according to research presented at the RSNA 2020 virtual meeting. A new study found CESM yielded 93% accuracy for identifying high-grade ductal carcinoma in situ.  Discuss
From alligators to COVID-19, 3D images show lung pathology
December 2, 2020 -- What do 3D reconstructed images of alligators have to do with COVID-19? Researchers from Louisiana who began working together to image reptiles have leveraged their collaboration into a 3D method for visualizing lung pathology in cases of COVID-19.  Discuss
Machine-learning model predicts adverse cardiac outcomes
December 1, 2020 -- A machine-learning algorithm for analysis of coronary CT angiography exams was able to predict major adverse cardiac events at a higher level of accuracy than other traditional risk scores and risk factors, according to a presentation on Tuesday morning at the virtual RSNA 2020 meeting.  Discuss
Atlas resigns as White House COVID-19 adviser
December 1, 2020 -- Neuroradiologist Dr. Scott Atlas on November 30 announced his resignation as an adviser on COVID-19 to the Trump administration. Atlas' four-month tenure in the position was marked by controversy due to statements he made in opposition to lockdown measures.  Discuss
EVALI shows particular imaging findings on CT
December 1, 2020 -- Particular CT imaging findings such as a diffuse alveolar damage pattern can help radiologists diagnose electronic cigarette or vaping product use-associated lung injury (EVALI), according to a presentation delivered on Monday at the virtual RSNA 2020 meeting.  Discuss
3D printing makes giant strides in liver
December 1, 2020 -- 3D models that combine vascular and biliary anatomy using different imaging techniques can contribute to more rigorous planning of complex liver operations, including hepatic resections, living-donor transplantation, vascular intervention procedures, and biliary reconstruction surgery, Portuguese researchers reported at RSNA 2020.  Discuss
GE products at RSNA 2020 include AI-enhanced imaging
December 1, 2020 -- GE Healthcare is demonstrating a slate of new imaging technologies at this week's virtual RSNA 2020 meeting, including the latest version of its interventional imaging platform, a new 3D mobile C-arm, and an array of products enhanced with artificial intelligence (AI).  Discuss
MRI, ultrasound diagnose post-COVID-19 muscle weakness
December 1, 2020 -- A combination of MR neurography and ultrasound could help clinicians better diagnose what is causing some recovered COVID-19 patients to continue to experience chronic pain, numbness, or weakness in their hands or limbs, according to commentary published December 1 in Radiology.  Discuss
AI catches interval breast cancers missed by rads
December 1, 2020 -- Artificial intelligence (AI) software could help cut down on the number of interval breast cancers, according to research presented Monday at the 2020 virtual RSNA meeting. An AI program detected more than one-third of breast cancers missed on screening mammography in two different studies.  Discuss
Can AI software drive CT lung screening rates higher?
December 1, 2020 -- Can software based on artificial intelligence improve the anemic rates of CT lung cancer screening in the U.S.? That's the hope of Infervision, whose InferRead Lung CT.AI software won the Minnies award for Best New Radiology Software. The application is designed to automatically detect lung nodules on chest CT exams.  Discuss
