3D models advance therapy for heart rhythm disorders
August 21, 2019 -- 3D heart models based on MRI scans allowed for the virtual simulation of existing and future irregular heartbeats in patients with atrial fibrillation in a new study, published online August 19 in Nature Biomedical Engineering. The models helped pinpoint distinct regions in the patients' heart that would benefit most from ablation therapy.  Discuss
Which nuclear modality has the lowest dose for CHD?
August 21, 2019 -- Reducing radiation exposure from myocardial perfusion imaging is a key priority, especially for congenital heart disease (CHD) patients who face repetitive scanning. Which nuclear imaging modality and radiotracer are best for this task is the subject of a study published August 12 in the Journal of Nuclear Cardiology.  Discuss
Data biases for AI could worsen healthcare disparities
August 21, 2019 -- Careful stewardship of the integrity of big data is crucial to ensure that inherent biases contained in datasets used to train artificial intelligence (AI) algorithms don't make existing disparities in healthcare even worse, according to an article published online August 19 in npj Digital Medicine.  Discuss
MRI shows vaping compromises vascular function
August 20, 2019 -- Findings from MRI scans show that vaping immediately affects vascular function, even when the liquid solution contained in the electronic cigarette (e-cigarette) does not contain nicotine, according to a study published August 20 in Radiology.  Discuss
Is radiology corporatization positive or negative?
August 20, 2019 -- Corporatization in radiology is increasing, and whether it is a positive or negative trend remains to be seen, according to a white paper published August 16 in the Journal of the American College of Radiology.  Discuss
Gadolinium MRI scans most common early in pregnancy
August 20, 2019 -- Pregnant women are four times more likely to undergo an MRI scan with a gadolinium-based contrast agent in their first trimester than in their final six months of pregnancy, a finding that indicates many are scanned before they know they are pregnant, according to a study published online August 20 in Radiology.  Discuss
4 applications of cinematic rendering in maxillofacial CT
August 20, 2019 -- Swiss researchers have used cinematic rendering to create photorealistic images of head CT and conebeam CT scans. They assess the potential benefits of integrating these images into the evaluation of maxillofacial anatomy and pathology in a study recently published online in Dentomaxillofacial Radiology.  Discuss
Preparing healthcare IT architecture for AI: Part 2
August 20, 2019 -- Preparing IT architecture for artificial intelligence (AI) and business intelligence and analytics in radiology requires a broad strategic architectural perspective and governance that often have been lacking at healthcare institutions, according to Dr. Paul Chang of the University of Chicago.  Discuss
First look at new Medicare rules for 2020
August 20, 2019 -- The U.S. Centers for Medicare and Medicaid Services (CMS) has released its annual proposal for changes to the Medicare payment system for the coming year, explains Sandy Coffta from Healthcare Administrative Partners. CMS has also released new information about the existing mandate for the use of clinical decision support beginning in 2020.  Discuss
Is it time to implement CT lung screening in Asia?
August 19, 2019 -- A computer-based simulation model projected that CT lung screening in several Asian countries could reduce lung cancer deaths by nearly 5% in a new study, recently published online in PLoS One. These populations are likely to benefit greatly from widespread implementation of CT lung screening, researchers say.
