4D flow MRI shows smallest hint of LV dysfunction
August 23, 2016 -- Four-dimensional flow MRI can depict even subtle changes in left ventricular (LV) function, bringing new insight to the diagnosis of patients with mild left ventricular dysfunction and remodeling, concludes a study published on 17 August in PLOS One.
Can femoral ultrasound find role in CV risk assessment?
July 26, 2016 -- By spotting atherosclerotic plaques that aren't also present in the carotid artery, femoral ultrasound can predict the risk of cardiovascular (CV) disease in many asymptomatic patients who would be overlooked if they only received carotid ultrasound, according to research from Italy published online in Angiology.
MR alternative: CT shows value in cardiomyopathy
July 25, 2016 -- CT now has an important role in most kinds of cardiomyopathies, owing to its strength in morphological assessment and its ability to visualize calcium and coronary artery disease, according to a presentation at the International Symposium on Computed Tomography.
FFR-CT makes the grade in clinical practice
July 25, 2016 -- Using fractional flow reserve CT (FFR-CT) to assess the severity of coronary disease at CT angiography offers powerful advantages in daily clinical practice, but to use it optimally, practitioners must create a place for the noninvasive procedure in their practices and know when to stay away, according to a Dutch expert.
CT myocardial perfusion imaging evolves
July 21, 2016 -- As researchers gain experience with CT myocardial perfusion imaging (MPI), they're finding MPI remains harder to read than fractional flow reserve CT. But CT MPI still has a lot going for it, including its potential to reduce catheterizations in patients with suspected coronary artery disease.
Very low calcium scores do not guarantee negative MPI
July 14, 2016 -- Symptomatic patients with very low coronary artery calcium scores are almost as likely to have a positive SPECT myocardial perfusion imaging (MPI) scan and a subsequent cardiac event as patients with higher calcium scores, according to a study presented at the Society of Nuclear Medicine and Molecular Imaging annual meeting.
Mobile App Spotlight: CMR Pocket Guide
July 12, 2016 -- Cardiac MRI can be an intimidating modality to learn, but the CMR Pocket Guide aims to simplify tasks and can be useful both for education and in daily practice. We interviewed one of the app's co-developers, Dr. Bernhard Herzog from Lucerne, Switzerland.
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.
