Algorithm detects LVO stroke on multiphase CTA
September 29, 2020 -- An artificial intelligence algorithm can be extremely sensitive for detecting large-vessel occlusion (LVO) on multiphase CT angiography (CTA) scans, potentially speeding up diagnosis and hastening stroke treatment in these patients, according to research published online September 29 in Radiology.  Discuss
AI training sets often aren't geographically diverse
September 29, 2020 -- Clinical artificial intelligence (AI) algorithms across multiple disciplines -- including radiology -- are disproportionately trained on patient cohorts from three states: California, Massachusetts, and New York, according to a research letter published September 22 in the Journal of the American Medical Association.  Discuss
Race affects access to prostate cancer PET
September 28, 2020 -- Black men have less access to PET imaging for recurrent prostate cancer with a radiotracer that appears to be more effective than the more commonly used F-18 fluciclovine, according to a study published September 25 in the Journal of Nuclear Medicine.  Discuss
AI boosts rads' COVID-19 x-ray diagnosis performance
September 28, 2020 -- An artificial intelligence (AI) algorithm called CV19-Net boosted the performance of thoracic radiologists when it came to distinguishing COVID-19 pneumonia from other types of pneumonia on chest x-ray, according to a study published September 24 in Radiology.  Discuss
Synthetic DBT images could replace digital mammo
September 25, 2020 -- A new, 200,000-patient review suggests that 2D images reconstructed from digital breast tomosynthesis (DBT) may be able to adequately replace digital mammograms. The Canadian team behind the paper published their findings on September 23 in the American Journal of Roentgenology.  Discuss
Researchers offer a guide to optimum PET lung imaging
September 25, 2020 -- Can you name the best strategies to optimize FDG-PET/CT to assess lung disease? If not, researchers from imaging centers in the U.S. and the U.K. have provided their consensus recommendations on how best to proceed in a study published online September 18 in the Journal of Nuclear Medicine.  Discuss
Pocket-sized ultrasound delivers big results for COVID
September 25, 2020 -- A pocket-sized ultrasound scanner powered by a smartphone performed comparably to a cart-based scanner for lung imaging at the point of care in patients with COVID-19, according to a study published on September 21 in Ultrasound in Medicine and Biology.  Discuss
Notification laws may not lead to more breast screening
September 25, 2020 -- Breast density notification laws may not prompt mammography facilities to offer additional screening services. A North Carolina survey found that fewer than two-thirds of breast imaging locations offered supplemental screening for women with dense breasts, according to a September 14 study in Cancer.  Discuss
COVID-19 patients more likely to have thromboembolism
September 24, 2020 -- Patients with COVID-19 are more likely to have thromboembolism than those without the disease, according to a report published September 24 in the American Journal of Roentgenology.  Discuss
AMVC Fall 2020: AI can improve efficiency, reduce stress
September 24, 2020 -- The second article in a two-part series on Dr. Eliot Siegel's presentation at's Fall 2020 Virtual Conference (AMVC) details how artificial intelligence (AI) could help radiologists be more efficient and productive -- as well as less stressed -- during and after the COVID-19 pandemic.  Discuss
