CT radiomics classifies small nodules found in CT lung screening
January 15, 2021 -- A machine-learning algorithm can be highly accurate for classifying very small lung nodules found in low-dose CT lung screening programs, according to a poster presentation at this week's American Association for Cancer Research Virtual Special Conference on Artificial Intelligence, Diagnosis, and Imaging.  Discuss
Mammograms for inpatients could boost screening rates
January 15, 2021 -- Offering mammograms to low-income patients during an inpatient hospital stay could boost screening rates, according to the findings of a small pilot study published on January 11 in the Annals of Family Medicine.  Discuss
How many cancers were missed during the COVID-19 pandemic?
January 14, 2021 -- Cancer diagnoses declined by double digits at a prominent Boston healthcare system during the early stages of the COVID-19 pandemic in spring 2020, according to an analysis published on January 14 in JAMA Oncology. Researchers estimated more than 1,400 lesions could have been missed in a three-month period.  Discuss
NCRP nixes gonadal screening, urges regulatory changes
January 14, 2021 -- The National Council on Radiation Protection and Measurements (NCRP) on January 13 advised against the routine use of gonadal shielding during abdominal and pelvic radiography. The change is in line with current scientific thinking on the risks of shielding, such as missed findings.  Discuss
Asians, Hispanics miss out on imaging during pandemic
January 14, 2021 -- Hispanic and Asian patients have been significantly less likely to get imaging studies during the COVID-19 pandemic, creating the risk of delayed diagnoses, according to a Brigham and Women's study published January 12 in the Journal of the American College of Radiology.  Discuss
Thyroid cancer screening hits the right note
January 13, 2021 -- Researchers from France discovered a thyroid cancer screening technique that hit all the right notes. The method can noninvasively detect abnormally stiff tissues on ultrasound when participants sing the "eeee" sound, according to a January 12 study in Applied Physics Letters.  Discuss
PET/CT guidance offers valuable approach to lung biopsies
January 13, 2021 -- One optimum way to reduce inconclusive lung biopsy results and better detect malignancies is to use FDG-PET/CT for the image-guided procedure. Researchers from Brazil found that PET/CT had advantages over conventional CT guidance.  Discuss
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
FDA publishes action plan for medical AI software
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
