The findings further illustrate the far-reaching nature of COVID-19 disease.November 17, 2020MRIMRI links air pollution to dementia risk in womenMRI scans show that women in their 70s and 80s who are exposed to higher levels of air pollution appear to be at increased risk of developing the type of brain shrinkage associated with Alzheimer's disease, according to a study published November 18 in the journal Neurology.November 17, 2020CTMachine learning boosts chest CT's performanceMachine learning-based CT texture analysis software improves reader accuracy for assessing patients with chronic obstructive pulmonary disease, interstitial lung diseases, or infectious diseases, according to a study published November 12 in the European Journal of Radiology.November 17, 2020MRIMRI shows negative impact of racket sportsSports like tennis and racquetball speed the breakdown of the knee joint in overweight people with osteoarthritis, according to research to be presented at the upcoming virtual RSNA 2020 conference. Such individuals might want to switch sports to avoid knee injury, the authors suggest.November 16, 2020CTRoad to RSNA 2020: CTThe COVID-19 pandemic has highlighted CT's usefulness as a diagnostic tool -- especially in the early days of the outbreak, when laboratory tests were scarce and results were delayed. Attendees at RSNA 2020 will learn about research demonstrating CT's efficacy in COVID-19 patients, as well as its use in cardiac imaging and other important areas.November 16, 2020CTCOVID-19, AI, and dose reduction top RSNA's CT agendaIn 2020, the COVID-19 pandemic has shaped the practice of imaging across all modalities, and CT is no exception. At the upcoming RSNA 2020 meeting, attendees are likely to hear significant discussion of how CT fits into the continuum of COVID-19 diagnosis and tracking. CT will also have its time in the spotlight for a range of other applications, such as its use with artificial intelligence (AI) to spot pulmonary embolism.November 16, 2020CTCT shows its value in the COVID-19 crisisAt the start of the COVID-19 pandemic, as researchers and clinicians rushed to determine the best ways to diagnose and treat the illness, chest CT proved to be a valuable tool -- particularly when reverse transcription polymerase chain reaction testing wasn't easily available or results were delayed.November 16, 2020Previous PagePage 83 of 356Next PageTop StoriesMolecular ImagingAmyloid PET scans validated in racially diverse patientsChanges in care plans occurred in 59% of individuals after PET scans.Womens ImagingLimited access to PCPs thwarts mammography screening uptakeUltrasoundPOCUS rules out pulmonary congestion in kidney patientsEconomicsLow-value imaging services part of high Medicare costsDigital X-RayAI helps clinicians identify misplaced endotracheal tubes
