Is CT or MR perfusion better for diagnosing CAD?
February 15, 2018 -- Recent advances in scanner technology have made the use of CT stress myocardial perfusion imaging feasible. Just how well it matches up to MR perfusion in the diagnosis of coronary artery disease (CAD) is the central question of a German/U.S. study led by Dr. Marc Dewey from Berlin.  Discuss
Machine learning can help assess atherosclerosis
February 7, 2018 -- Machine-learning techniques analyze imaging measurements to automatically stratify patients by the level of atherosclerotic burden, offering the potential of personalized prediction of disease progression and more effective treatment for individual patients, according to researchers from Italy.  Discuss
PET/MRI proves value in cardiac sarcoidosis detection
January 23, 2018 -- U.K. researchers are recommending the use of PET/MRI to assess suspected cases of cardiac sarcoidosis, with late gadolinium enhancement and FDG uptake as the key indicators of disease, according to a study published online on 8 January in the European Heart Journal.  Discuss
3D printing technique lowers cost of modeling stenosis
January 16, 2018 -- Radiologists can plan and simulate vascular procedures on patient-specific and cost-effective 3D-printed stenosis models by using a new technique developed in Basel, Switzerland. Researchers generated stenotic vessel replicas at a more affordable price than what's currently available.  Discuss
3D volumetry shows promise in lung but requires care
January 12, 2018 -- Volumetry measurement of lung nodules is gaining clinical acceptance but still poses significant practical difficulties, and major factors of variability are related to the nodule, technical scanner parameters, and hemodynamic issues, according to U.K. researchers.  Discuss
How often are lung nodules missed on CAC scoring scans?
January 2, 2018 -- If an incidental lung nodule is present on a CT coronary artery calcium (CAC) scoring scan, how often is that nodule actually detected and worked up? Not as often as one might expect, according to researchers who analyzed the reasons why nodules might be missed in a presentation at RSNA 2017.  Discuss
CT can pinpoint cardiac metastases in malignant melanoma
December 19, 2017 -- CT tends to underestimate cardiac metastases in malignant melanoma patients, and to reduce morbidity and mortality in these cases, awareness is essential of different types of cardiac metastases and their characteristic appearance on CT, German researchers have found.  Discuss
AI assesses cardiovascular risk on routine chest CT
December 12, 2017 -- An artificial intelligence (AI) algorithm can automatically quantify coronary and other arterial calcification from routine chest CT studies, enabling cardiovascular risk assessment to be performed on these patients, Dutch researchers reported at the RSNA 2017 meeting.  Discuss
Deep learning can quantify CAC on low-dose CT
November 29, 2017 -- CHICAGO - A deep-learning algorithm can automatically calculate coronary artery calcium (CAC) scores from lung cancer screening CT exams and facilitate risk stratification in these patients, according to research presented on Tuesday at RSNA 2017.  Discuss
MRI discovers heart damage among male triathletes
November 24, 2017 -- Using late gadolinium-enhanced MRI scans, German researchers found myocardial fibrosis, or scarring of the heart, among competitive male triathletes. An increased risk of scarring was associated with the amount of exercise performed, according to the group, who will present the study at next week's RSNA meeting in Chicago.  Discuss
