Cardiac PET predicts outcomes in aortic stenosis
September 16, 2021 -- PET imaging has shown how impaired blood flow in small vessels of the heart may lead to myocardial stress and injury in patients with aortic stenosis, according to a study published online September 15 in JAMA Cardiology. Read More

Strength in numbers: Federated learning boosts AI for COVID-19
September 16, 2021 -- An algorithm trained using federated learning turned in highly accurate performance for predicting clinical outcomes in COVID-19 patients from chest x-rays and clinical data, according to research published online September 15 in Nature Medicine. Read More

Synthesized mammo plus DBT handles calcifications differently
September 16, 2021 -- A new study has found similarities between the performance of digital breast tomosynthesis (DBT) combined with synthesized mammography and the performance of DBT plus full-field digital mammography. But the two combinations differed in how they handled the recall of patients with calcifications. Read More

Deep learning reduces scan times for shoulder MRI
September 16, 2021 -- MRI reconstruction based on deep learning for shoulder exams allows clinicians to reduce scan times via accelerated protocols without compromising image quality, according to a study published September 15 in the American Journal of Roentgenology. Read More

Falling MRI scanner kills worker at Utah hospital
September 15, 2021 -- An MRI scanner that was being relocated killed a worker on September 15 when it fell to the ground outside the University of Utah Hospital. Another worker was injured in the incident, which is under investigation. Read More

Researchers tout algorithm that predicts breast cancer risk with DBT
September 15, 2021 -- Calculations of breast density that are derived from digital breast tomosynthesis (DBT) exams may be more accurate than those derived from conventional 2D mammography in predicting cancer risk, according to research published September 14 in Radiology. Read More

Chest CT score predicts ventilation failure in COVID-19 patients
September 15, 2021 -- Scores of disease severity based on CT scans can help predict how COVID-19 patients will respond to noninvasive ventilation administered through an oxygen mask rather than through intubation, according to a study published September 11 in the Journal of Cardiothoracic and Vascular Anesthesia.

CT lung screening reduces lung cancer mortality 16% in U.K. study
September 14, 2021 -- Performing CT lung cancer screening of current and former smokers reduced lung cancer mortality by as much as 16%, a number in line with other studies, according to research published on September 11 in the Lancet Regional Health -- Europe. Read More

MRI radiomics can help predict breast cancer treatment response
September 14, 2021 -- A nomogram based on MRI radiomics and clinical variables can predict whether hormone receptor-positive breast cancer patients will respond to endocrine therapy, according to research published online September 11 in the Breast. Read More

POCUS can help with intussusception in pediatric patients
September 14, 2021 -- Point-of-care ultrasound (POCUS) is helpful in pediatric emergencies for differentiating ileocolic intussusception from small bowel-small bowel intussusception, according to a study published September 11 in the Journal of Emergency Medicine. Read More
