FDA faces research hurdles in regulating AI for imaging
September 20, 2021 -- What's taking so long for artificial intelligence (AI) algorithms to move into routine clinical use in radiology? Several regulatory bottlenecks could be holding AI back, according to a September 19 talk at the Conference on Machine Intelligence in Medical Imaging. Read More

Can AI help improve racial disparities in healthcare?
September 20, 2021 -- If appropriate steps are taken, artificial intelligence (AI) technology could help reduce -- not worsen -- racial disparities in healthcare in the U.S., according to an article published September 17 in JAMA Health Forum. Read More

Clinicians in Japan use navigation system for TMJ surgery

Dedicated CT lung cancer screening programs get the job done
September 17, 2021 -- A centralized lung cancer screening approach -- that is, a dedicated program to which patients are referred by primary care providers -- is more effective than sending people to a general radiology department, according to a study published September 15 in Chest. Read More

Can radiomics and AI characterize renal masses on preop CT?
September 17, 2021 -- The combination of radiomics and a machine-learning algorithm can differentiate benign from malignant renal masses, potentially helping to avoid unnecessary surgeries, according to research published online September 17 in European Urology Focus. 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

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

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
