T1 maps can't pick healthy from diseased myocardium
June 21, 2016 -- Native T1 mapping may be the year's hottest cardiac imaging technique, but it can't do something it's expected to do: distinguish healthy from diseased myocardium. That's the key finding by researchers from Essen University Hospital in Germany.
High iodine concentrations don't improve CCTA
June 20, 2016 -- Using higher iodine concentrations when performing coronary CT angiography (CCTA) yields no significant improvement in contrast attenuation, concludes a new study led by cardiac imaging pioneer Dr. Stephen Achenbach.
Ultralow contrast achievable in high-pitch CCTA
May 20, 2016 -- How low can a contrast dose go? Researchers have found excellent coronary CT angiography (CCTA) results with ultralow contrast and radiation doses when they tested several protocols with high-pitch dual-source CT scanning.
Cardiac MRI beats SPECT for predicting heart events
May 12, 2016 -- Cardiovascular MRI is a better prognosticator of risk for serious cardiovascular events than SPECT, regardless of a person's risk factors, angiography results, or initial treatment, according to a study published online in the Annals of Internal Medicine.
French use intervention to boost care in fibroid cases
May 5, 2016 -- Researchers in France have evaluated the impact of uterine fibroid embolization on the quality of life of women with uterine fibroids. They presented their findings at the recent Society of Interventional Radiology annual meeting in Vancouver, British Columbia.
Visceral fat tied to coronary disease
May 4, 2016 -- When it comes to the risk of coronary artery disease, not all fat is created equal, say Hungarian researchers. They found that at least one type of visceral fat correlates with the presence of coronary artery disease.
Guidelines issued for imaging prosthetic heart valves
May 4, 2016 -- New guidelines for multimodality imaging and diagnosis of prosthetic heart valves have been issued by the European Association of Cardiovascular Imaging.
CCTA falls short in detecting culprit plaque
April 21, 2016 -- In a population of myocardial infarction patients spanning 10 years of clinical practice, coronary CT angiography (CCTA) showed only limited ability to detect culprit lesions in the coronary arteries that went on to cause heart attacks -- though its positive predictive value was perfect, researchers concluded.
U.K. launches massive scanning project
April 18, 2016 -- A U.K. research organization said it has launched a large study across the country that will involve scanning more than 100,000 participants to transform the way medicine looks at a wide variety of diseases including dementia, arthritis, cancer, heart attacks, and stroke.
Cardiac cath radiation exacts toll on health personnel
April 14, 2016 -- Radiation from cardiac catheterization procedures is taking a heavy toll on cath lab personnel, according to a new study published April 12 in Circulation: Cardiovascular Interventions. Italian researchers found higher rates of orthopedic problems, cataracts, skin lesions, and even anxiety and depression in cath lab workers.
