Better chest CT CAC reporting avoids unnecessary exams
January 13, 2021 -- Reporting coronary artery calcium (CAC) on routine chest CT could help clinicians more accurately predict a patient's cardiovascular disease risk and avoid unnecessary additional gated calcium score CT exams, according to a study published in the January-February issue of Current Problems in Diagnostic Radiology.  Discuss
Could AI lower malpractice risk for physicians?
January 12, 2021 -- Although some legal scholars believe that liability concerns could hinder adoption of artificial intelligence (AI) software in personalized medicine, a new study published in the Journal of Nuclear Medicine found that physicians who follow the technology's advice may actually be shielded from malpractice liability.  Discuss

January 12, 2021 -- The U.S. Food and Drug Administration (FDA) has published an action plan for medical artificial intelligence (AI) algorithms that includes a draft guidance, efforts to harmonize good machine-learning practices, and development of methodologies for evaluating algorithms and monitoring their real-world performance.  Discuss
AI bolsters specificity of screening breast ultrasound
January 12, 2021 -- A diagnostic model that incorporates artificial intelligence (AI)-based quantitative analysis can significantly decrease false-positive rates for masses detected on screening breast ultrasound exams, potentially helping to reduce unnecessary biopsies, according to a study published online January 11 in Scientific Reports.  Discuss
Falling lung cancer rates drive cancer decline in U.S.
January 12, 2021 -- The death rate for people who have lung cancer in the U.S. continued to drop in 2020, according to a January 12 report from the American Cancer Society. The drop has contributed to a decline in cancer mortality of almost one-third in the last 20 years.  Discuss
Is there a place for whole-body cancer screening?
January 12, 2021 -- A whole-body imaging cancer screening program could be an effective way to detect early-stage cancer among a motivated screening population, according to a study from Japan published January 1 in the Journal of the American College of Radiology.  Discuss
Density notification laws are working -- but not equally
January 12, 2021 -- Dense breast notification laws appear to be providing more women with density information, but the gains are not equal across all types of women, according to the findings of a study published on December 24 in the Journal of the American College of Radiology.  Discuss
Can AI spot breast cancer years before radiologists?
January 11, 2021 -- A deep-learning algorithm successfully detected breast cancer on screening mammography, in some cases as early as two years before it was diagnosed during conventional interpretation, according to research published online January 11 in Nature Medicine. The algorithm also performed well with digital breast tomosynthesis (DBT) exams.  Discuss
Echo helps identify flossing-induced heart disease
January 11, 2021 -- In a case report from Texas, echocardiography helped clinicians diagnose a man with a rare case of infective endocarditis thought to be caused by oral bacteria released from vigorous dental flossing. The findings were published in the Cureus Journal of Medical Science.  Discuss
Are COVID-19 reviews relying on the same primary studies?
January 11, 2021 -- The scientific literature is being flooded with academic reviews of COVID-19 that are based on the same small set of primary studies, according to research published January 7 in JAMA Network Open. Researchers proved their point by analyzing studies of imaging of children with COVID-19.  Discuss
