Chest x-ray technique reduces radiation dose in infants
July 1, 2022 -- Radiation doses to neonates undergoing chest x-rays can be significantly reduced by using a high kilovoltage technique, according to a study using anthropomorphic phantoms published June 21 in Radiation Physics and Chemistry. Read More
Photon-counting CT proves value in driving down imaging dose
June 30, 2022 -- Photon-counting detector CT is showing promise as a way of reducing radiation dose by more than a third, researchers from Tübingen in Germany have reported. It enables oncologic abdominal CT with a much reduced dose while retaining image quality similar to dual-energy CT, they say. Read More
Heated debate resurfaces over breast screening’s effectiveness
June 29, 2022 -- A known anti-mammography screening research group has reignited the controversy over breast screening by claiming the technology’s benefits have significantly decreased over time while its harms (i.e., overdiagnosis) remain unchanged. Dr. László Tabár has issued a response. Read More
Ultrasound can be challenging for plastic surgeons
June 29, 2022 -- Interpreting ultrasonic images for use in plastic surgery can be challenging, including when it comes to lymphatic vessels or when no other information is available, a Spanish study published on 28 June in the Journal of Plastic, Reconstructive & Aesthetic Surgery found. Read More
Will you have to wear a face mask in Vienna next month?
June 28, 2022 -- Wearing a face mask won’t be mandatory at ECR 2022, but it will be required on public transport during a week when the Rolling Stones and Guns N’ Roses are playing at huge gigs in Vienna. Congress organizers say they will not check on ECR delegates’ COVID-19 vaccination status. Read More
Europe lags behind on clinical implementation of AI
June 28, 2022 -- A new European survey suggests that the use of artificial intelligence (AI) algorithms in clinical radiology remains limited, largely because the impact of these tools on the reduction of radiologists' workload is still unproven. Read More
CT shines new light on SARS-CoV-2 omicron variant
June 27, 2022 -- The SARS-CoV-2 omicron variant shows fewer and less severe changes on chest CT than its delta variant predecessor, but it does have at least one distinct manifestation, U.K. researchers have reported. Read More
Why radiologists and AI must work together on breast cancer screening
June 27, 2022 -- A breast cancer screening workflow that leverages the different strengths of radiologists and artificial intelligence (AI) software can improve overall accuracy and reduce workload, a large U.S.-German study has discovered. Read More
AI chest x-ray software displays clinical promise in children
June 24, 2022 -- A new study has found that an artificial intelligence (AI) algorithm initially cleared for analyzing chest x-rays of adult patients may also be effective for use in children. The algorithm was tested for identifying eight detectable lesions, and achieved an accuracy of 87.5%. Read More
Ultrasound use in low-income countries receives validation
June 23, 2022 -- A study conducted in rural Africa found that ultrasound can be used successfully by nonradiologists to detect lesions. The new data can be used to guide clinical protocols, including thresholds for biopsy of sonographically benign-appearing breast lesions, the lead author says. Read More
