Cardiovascular

 

Parents and doctors of children with heart disease have a new resource as they seek the best diagnostics with the least radiation. Called the “Have-a-Heart” campaign, it’s a collaborative effort led by the Image Gently Alliance together with the American Academy of Pediatrics and a coalition of pediatric medicine and cardiology organizations.

Compared side-by-side with standard cardiac CT for calcium scoring, ultralow-dose CT shows good sensitivity, specificity and overall accuracy despite its markedly lower radiation dose. In fact, it’s unlikely to miss coronary calcification in patients with at least moderate calcium load and could offer a sensible alternative for some patients sent for coronary CT angiography.

Using CT coronary angiography, researchers concluded that gray hair has been linked to an increased risk of heart disease in men. The findings were presented at EuroPrevent 2017. 

Thanks to advances in MRI-compatible cardiac device technology, pacemakers and implantable cardioverter defibrillators (ICDs) are no longer absolute contraindications for MRI exams. The devices remain relative contraindications for MRI, however, and their presence in MRI patients calls for radiologists and cardiologists to work closely together in order to both ensure patient safety and minimize legal risk.  

The connection between chronic emotional stress and subsequent cardiovascular disease has long been substantiated on mostly circumstantial evidence. Now it’s been empirically established with imaging: A new study has put pictures to the heretofore unseen brain mechanism behind the mind/body double trouble.

Ultralow-dose CT shows potential to substitute for standard coronary calcium imaging

Carotid ultrasound usefully predictive in post-stroke care

Rapid stenting of the carotid artery can significantly reduce the risk of secondary stroke, and a new Taiwanese study shows that carotid ultrasound imaging can help predict likely functional outcomes following such stenting in ischemic stroke patients with carotid artery stenosis.

MRI of pacemaker patients requires close radiology+cardiology collaboration

Thanks to advances in MRI-compatible cardiac device technology, pacemakers and implantable cardioverter defibrillators (ICDs) are no longer absolute contraindications for MRI exams. The devices remain relative contraindications for MRI, however, and their presence in MRI patients calls for radiologists and cardiologists to work closely together in order to both ensure patient safety and minimize legal risk.  

Research explores laser-based imaging platform for atherosclerosis

A new laser-based camera could one day become the tool that will help physicians know who is at risk of atheroscerlosis, by providing better views of potential problem areas.

MRI provides new insight into different forms of heart failure

MRI was used to measure oxygen consumption in the legs of heart failure patients by researchers at the University of Texas, who from this noninvasive technique gained extra insight into different forms of heart failure.

PET/CT shows how stress in the brain today manifests as cardiovascular problems tomorrow

The connection between chronic emotional stress and subsequent cardiovascular disease has long been substantiated on mostly circumstantial evidence. Now it’s been empirically established with imaging: A new study has put pictures to the heretofore unseen brain mechanism behind the mind/body double trouble.  

Machine learning proves a plus in cardiopulmonary care

Researchers have shown that machine learning of 3D patterns in cardiac MRI can improve accuracy when it comes to predicting survivability of—and potentially guiding care for—patients with high blood pressure in the lungs. 

MRI focuses on heart function of kidney patients receiving dialysis

Researchers at the University of Nottingham were the first to use MRI to study the heart function of kidney patients while they were receiving dialysis treatment.
