3 ways to lower CT radiation dose across the hospital
May 24, 2019 -- A hospital-wide quality improvement project effectively lowered CT radiation dose by nearly 20%, report researchers from Seattle. They detailed how three initiatives enabled them to achieve this dose reduction in an article published online May 21 in the Journal of the American College of Radiology.  Discuss
Can DBT replace FFDM?
May 24, 2019 -- Can digital breast tomosynthesis (DBT) replace full-field digital mammography (FFDM)? Yes, especially if wide-angle DBT is used, according to a study published in the June issue of the American Journal of Roentgenology.  Discuss
AI can optimize risk stratification of thyroid nodules
May 24, 2019 -- An artificial intelligence (AI) algorithm improved the specificity of the American College of Radiology Thyroid Imaging Reporting and Data System, while also making the thyroid nodule risk-classification system easier for radiologists to use, according to research published online May 21 in Radiology.  Discuss
CT lung screening risk model cuts false-positive rate
May 23, 2019 -- Using a risk prediction model to figure out which nodules to work up helped reduce the false-positive rate in a CT lung cancer screening trial by more than threefold, compared with rates using previous criteria, according to an article published online May 15 in the Journal of the American College of Radiology.  Discuss
CAD software helps avoid contrast use in MS patients
May 23, 2019 -- Using computer-aided detection (CAD) software, 3D laboratory radiologic technologists can determine if patients with multiple sclerosis (MS) need a contrast agent for their brain MRI exam while they're still in the scanner, according to research posted online May 16 in the Journal of the American College of Radiology.  Discuss
3D printing customizes brachytherapy for cervical cancer
May 23, 2019 -- Researchers from the Netherlands have created individually tailored 3D-printed brachytherapy applicators based on the MRI scans of patients with cervical cancer, potentially improving access to tumors during treatment, according to an article published online recently in 3D Printing in Medicine.  Discuss
Medicaid expansion boosted cancer screening rates
May 22, 2019 -- The five states and the District of Columbia that expanded their Medicaid coverage after the Patient Protection and Affordable Care Act of 2010 first went into effect showed larger increases in cancer screening rates than states that did not, according to a study published online May 22 in the American Journal of Preventive Medicine.  Discuss
3 reasons why annual mammography is best
May 22, 2019 -- Mammography screening performed annually is the best option for women age 40 to 49, according to a review published online May 15 in the Journal of Breast Imaging. Annual screening is recommended for three main reasons, not least of which is a reduction in breast cancer mortality between 29% and 49%.  Discuss
Google AI accurately assesses CT lung screening scans
May 22, 2019 -- An artificial intelligence (AI) model developed by Google can assess cancer risk on CT lung cancer screening studies as well as, or even better than, experienced radiologists -- potentially enabling automated evaluation of these exams, according to research published online March 20 in Nature Medicine.  Discuss
fMRI may speed up diagnosis of autism
May 22, 2019 -- Using functional MRI (fMRI) to gauge a child's neurological responses to different visual stimuli, researchers believe they have developed a faster way to diagnose autism, according to a study in the current online edition of Biological Psychology.  Discuss
