Radiology responds in wake of Barcelona attack
August 23, 2017 -- The medical response to the terrorist attack in Barcelona on 17 August was amazingly quick and effective, said Dr. Lluís Donoso-Bach, PhD. Life in the city is gradually returning to normal, and the European Society of Cardiology's annual congress is still going ahead on 26 August.  Discuss
JAMA: PET best option to diagnose ischemic heart disease
August 21, 2017 -- A head-to-head comparison to determine the most accurate modality for diagnosing myocardial ischemia has found that PET outperforms SPECT, coronary CT angiography, and hybrid variations of the three modalities in patients with suspected coronary artery disease, according to a study published online August 16 in JAMA Cardiology.  Discuss
3D-printed blood vessels reproduce patient clots
August 17, 2017 -- Dutch researchers have created a blood-vessel model that effectively replicates the formation of a blood clot caused by stenosis defects. The team developed a microfluidic blood-vessel model using layered stacks of CT angiography data combined with 3D printing.  Discuss
CT CAC scoring tops age for predicting heart disease risk
August 4, 2017 -- Is age just a number? Maybe, at least for predicting atherosclerotic cardiovascular disease events in older adults. Coronary artery calcium (CAC) scoring with CT is better than a patient's age for predicting risk -- particularly for coronary heart disease, according to research published online on July 26.  Discuss
Zurich team moves ahead on heart replacements
July 28, 2017 -- A Swiss group has developed a soft 3D-printed silicone heart that beats almost like a human heart. The technique, which uses CT images of a real patient to create a computer-aided design model in 3D, could provide tailor-made, soft artificial hearts in the future.  Discuss
Vorwerk: Don't be afraid of the future
July 24, 2017 -- Will computers replace radiologists? Absolutely not, says Dr. Dierk Vorwerk, German Radiological Society deputy president. In a wide-ranging interview, he elaborates on the country's new expert network and speaks about machine learning's future impact.  Discuss
New CT technique identifies blood vessel plaque
July 13, 2017 -- A new CT technique can measure blood vessel inflammation, allowing doctors to identify and treat patients at risk for cardiovascular disease, according to a U.K. study published online 12 July in Science Translational Medicine.  Discuss
3D ultrasound quantifies subclinical atherosclerosis
July 11, 2017 -- While detecting subclinical atherosclerosis is useful, quantifying the plaque burden is even more valuable. A 3D vascular ultrasound method can reliably perform this task and help estimate cardiovascular risk, according to research published in the 18 July issue of the Journal of the American College of Cardiology.  Discuss
Motion compensation improves cardiac PET
July 3, 2017 -- Cardiac PET is used to measure tissue viability, myocardial perfusion, and functional parameters such as ejection fraction (EF). The EF provides valuable information for patients with heart disease. Now, researchers have developed a method to compensate for respiratory motion.  Discuss
Elastography can help evaluate carotid plaque
June 23, 2017 -- A shear-wave ultrasound elastography method can be used to evaluate the stability of carotid plaques, helping to identify those that are most vulnerable to rupturing and causing a stroke, according to a study published in the June issue of the Journal of Ultrasound in Medicine.  Discuss
