T1 mapping speeds myocardial assessment in cardiac MR
February 1, 2016 -- Researchers in Italy are saving time in their use of cardiac MRI to assess myocardial viability by using native T1-weighted mapping instead of a cumbersome T2-weighted imaging approach, according to a new study that compared both methods and found the latter wanting.
Automated contrast evens attenuation across weight ranges
January 26, 2016 -- Dutch researchers are reducing the contrast dose and achieving consistent results in a coronary CT angiography method that tailors the scanning protocol automatically according to patient weight. The technique delivers consistent coronary artery enhancement in multiple weight categories.
Lead protects pacemakers from radiation
January 15, 2016 -- Lead shields provide a simple and inexpensive way to reduce radiation delivered to pacemakers during radiation therapy, according to a new study. The protection is modest in many instances, but can in some cases reduce radiation by 40%, cutting the risk of pacemaker failure.
Global survey puts renewed emphasis on dose
January 8, 2016 -- European hospitals perform nuclear cardiology at lower doses than the rest of the world, and they use more of the best practices that have been identified, according to the results of a global survey published in the European Journal of Nuclear Medicine and Molecular Imaging.
CT breaks new ground in assessing heart valves
January 5, 2016 -- Third-generation dual-source CT scanners can now provide fast, comprehensive, and complementary information in the evaluation of mechanical heart valves, award-winning Dutch researchers reported at last month's RSNA meeting in Chicago.
MRI shows how heart changes during deep dives
December 2, 2015 -- CHICAGO - Cardiac MRI has uncovered the unusual ability of free divers -- who descend hundreds of feet into the ocean while holding their breath -- to develop "compensatory mechanisms" to recover heart function within minutes of breathing again.
Germans get star billing at RSNA with vast MRI study
December 1, 2015 -- Taking a broader approach to research, combined with much closer collaboration between radiologists and epidemiologists, can contribute to better patient care and disease prevention, according to speakers from Germany at a special session held at RSNA 2015 on Monday.
Socioeconomic status weighs heavily in cardiac risk
November 17, 2015 -- Germans of lower socioeconomic status have more than twice the risk of developing cardiovascular disease than the better-off -- and the differences may have widened in recent years, according to new research from the 2015 European Society of Cardiology (ESC) meeting in London.
Rubidium PET/CT reveals vascular problems in diabetes patients
November 16, 2015 -- Danish researchers have found high rates of microvascular disease using PET/CT with a rubidium radiopharmaceutical in diabetes patients without symptoms of heart disease. The disease was exacerbated in the setting of albuminuria, a common condition in these patients, according to a new study in Diabetologia.
Combined cardiac catheter treats and monitors
November 16, 2015 -- A proof-of-concept experiment with a combined high-intensity focused ultrasound and local harmonic motion imaging catheter has shown that the minimally invasive catheter can function as a therapeutic and monitoring tool for cardiac ablation, Canadian researchers found.
