Rubidium PET/CT reveals vascular problems in diabetes patients

By Eric Barnes

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

By Cynthia E. Keen

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

By Eric Barnes

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

By Philip Ward

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

By Tami Freeman, PhD

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

By Eric Barnes

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

By Eric Barnes

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

By Eric Barnes

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.
