Dutch researchers launch DENSE breast MR trial
July 9, 2015 -- It's well-known that mammography is less effective in women with dense breast tissue. But what hasn't been established is which supplemental modality is best for these women. Dutch researchers have launched a trial to study the use of MRI in addition to mammography for screening women with dense breast tissue.
A (myocardial) bridge too far: CT vs. IVUS in the heart
July 8, 2015 -- Multidetector-row CT should be considered the noninvasive gold standard when evaluating myocardial bridge abnormalities, owing to its anatomic accuracy. But there are important things CT doesn't see that intravascular ultrasound (IVUS) does, according to new research from Stanford University.
Coronary calcium CT scans predict mortality
July 7, 2015 -- A simple coronary calcium CT scan can be used to predict death in asymptomatic individuals for as long as 15 years after the scan, according to a new study of nearly 10,000 people, published in the July 7 issue of the Annals of Internal Medicine.
MRI ties small brain lesions to risk of stroke, death
July 7, 2015 -- Asymptomatic patients may have triple the risk of stroke and death if they have brain lesions smaller than 3 mm on 1.5-tesla MRI, a new study concludes. Furthermore, if the patients also have lesions 3 mm or larger, they may face an eightfold increase in stroke risk.
