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.
Italians pinpoint coronary plaque rupture risks November 13, 2015 -- Coronary plaque rupture and thin-cap fibroatheroma are common in patients with coronary artery disease, for whom clinical factors and bad habits like smoking increase the risk even more, according to an Italian meta-analysis in the European Heart Journal -- Cardiovascular Imaging.
How to cut dose if you lack iterative reconstruction October 30, 2015 -- Iterative reconstruction is fast becoming the magic bullet for CT dose reduction, but if you have an older CT scanner without this function, what can you do? Adjusting the scanning range of CT pulmonary angiography cuts dose by 24% and is safe, with a low recall rate, U.K. researchers have reported.
Cardiac ablation: Improving the accuracy October 27, 2015 -- Shear-wave elastography is showing promise for guidance of focused ultrasound-based cardiac ablation. Researchers from France have designed a transesophageal device that can both deliver high-intensity focused ultrasound and perform imaging.
CT technique can reduce invasive heart tests October 26, 2015 -- In what is thought to be the largest trial of its kind to date, U.S. and Italian researchers have found that an algorithm measuring blood flow through the coronary arteries based on data from CT images can prevent unnecessary catheterizations.
MRI proves value in coronary artery disease October 12, 2015 -- For patients with suspected coronary artery disease, initial perfusion cardiac MR plus invasive angiography if needed is cheaper than initial invasive angiography or angiography plus fractional flow reserve, according to research at last month's European Society of Cardiology meeting.
Automated calcium scoring CT is fast, accurate September 29, 2015 -- Dutch researchers have built an algorithm that identifies and quantifies coronary artery calcium from CT scans, paving the way for faster deployment of a test that is increasingly important in measuring the likelihood of heart disease.
Use of chaperones can help in intimate exams September 23, 2015 -- For anybody with a fear of conducting intimate patient examinations, help is at hand. The U.K. Royal College of Radiologists has published a special free document that includes practical guidance on the use of chaperones and other hot topics.
