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
Head CT offers low diagnostic yield for fainting
May 21, 2019 -- More than half of all patients who faint still undergo head CT despite a diagnostic yield of less than 3% for the exam, according to an article published in the May issue of Academic Emergency Medicine. Researchers from Canada say it's high time to cut back on using the test for most patients.  Discuss
How does chemo during pregnancy affect child development?
May 21, 2019 -- Chemotherapy performed on women during pregnancy could adversely affect long-term cortical development in their children's brains, according to a preliminary study presented last week at the International Society for Magnetic Resonance in Medicine annual meeting in Montreal.  Discuss
Contrast mammo boosts reader confidence for dense tissue
May 21, 2019 -- Contrast-enhanced mammography not only improves reader performance in interpreting mammograms in women with dense tissue but also boosts diagnostic confidence when compared with mammography alone, according to a study published online May 16 in the Journal of the American College of Radiology.  Discuss
