Augmented reality supports liver tumor ablation
June 16, 2020 -- Augmented reality technology shows potential for improving the speed and safety of liver tumor ablation procedures, according to research presented during a virtual session of the Society of Interventional Radiology's annual scientific meeting.  Discuss
Deep learning detects HCC on contrast-enhanced MRI
June 12, 2020 -- A deep-learning algorithm can detect hepatocellular carcinoma (HCC) on contrast-enhanced liver MRI exams within seconds and at an accuracy level comparable to a less-experienced radiologist, according to a preliminary study published online June 11 in Scientific Reports.  Discuss
Muscle metrics on chest CT can predict mortality risk
June 12, 2020 -- Measurements of muscle mass and density automatically extracted from chest CT exams using an artificial intelligence (AI)-based model can predict all-cause mortality over a six-year period in older men, according to research published online June 6 in the Journals of Gerontology.  Discuss
Gender imbalance in AI training datasets lowers results
June 9, 2020 -- Artificial intelligence (AI) algorithms trained with more cases from one gender can yield biased computer-aided diagnosis applications that perform worse on imaging exams involving the other gender, according to research published online May 26 in the Proceedings of the National Academy of Sciences.  Discuss
Functional, diffusion MRI could benefit from AI
June 8, 2020 -- For a variety of reasons, functional and diffusion MRI haven't been particularly hot research areas for artificial intelligence (AI). But these advanced imaging modalities do offer a ripe opportunity, according to a presentation at the virtual 2020 American Society of Neuroradiology meeting.  Discuss
3D-printed swabs make the grade for COVID-19 testing
June 5, 2020 -- Nasopharyngeal swabs produced by 3D printing can provide comparable results to traditional swabs for SARS-CoV-2 reverse transcription polymerase chain reaction testing, according to research from Beth Israel Deaconess Medical Center recently published online in the Journal of Clinical Microbiology.  Discuss
AI boosts assessment of cancer treatment response
June 3, 2020 -- Artificial intelligence (AI) software can significantly enhance assessment of cancer treatment response on serial CT exams by reducing errors, speeding up interpretations, and decreasing interobserver variability, according to research presented May 29 at the online American Society of Clinical Oncology meeting.  Discuss
AI can handle quality assessment of 3D cardiac MRI
June 2, 2020 -- An artificial intelligence (AI) algorithm can automatically assess image quality on 3D whole-heart cardiac MR images, achieving results similar to a human expert, according to research published online May 27 in Radiology: Artificial Intelligence.  Discuss
AI can aid radiologists in detecting pancreatic cancer
June 1, 2020 -- An artificial intelligence (AI) algorithm helped radiologists from Taiwan improve their performance in detecting pancreatic cancer on CT exams, demonstrating strong performance across a range of ethnicities, according to research published online May 26 in Lancet Digital Health.  Discuss
Gadolinium levels increase sharply in Tokyo rivers
May 28, 2020 -- The amount of gadolinium found in rivers around Tokyo has risen sharply over the last two decades, in line with a rapid proliferation of MRI scanners and an increasingly aging population that receives more contrast-enhanced exams, according to research published in the May issue of Marine Pollution Bulletin.  Discuss
