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
Initial stress echo safe, cheap for high-risk patients
June 21, 2017 -- Stress echocardiography is as effective and cheaper than direct referral to invasive coronary angiography in chest pain patients with a high pretest probability of coronary artery disease -- and appears competitive with rival coronary CT angiography as an initial exam.  Discuss
3D-printed polymer stents evolve
May 30, 2017 -- A new 3D-printed polymer stent overcomes many of the limitations of conventional nitinol stents for use with tissue-engineered heart valves, offering the potential of use in children, according to an article in 3D Printing and Additive Manufacturing.  Discuss
Fast cardiac MR scan can boost patient care
May 26, 2017 -- A fast and relatively cheap cardiovascular MR (CMR) scan is a cost-effective way to scan large volumes of patients with a wide range of suspected heart conditions, said researchers from Peru in a presentation on 26 May at the EuroCMR 2017 meeting in Prague.  Discuss
Hands-on approach can bring success in cardiac training
May 16, 2017 -- The rising demand for cardiac imaging and the rapid development of technology mean trainees often are squeezed for time, but there are several essential ingredients for successful training in cardiac imaging that will equip facilities for the future, according to Dr. Francesca Pugliese, PhD.  Discuss
CZT-based SPECT MPI may predict cardiac outcomes
May 12, 2017 -- SPECT gamma cameras featuring cadmium zinc telluride-based (CZT) digital detector technology are just what the nuclear cardiologist ordered to diagnose seemingly healthy patients with cardiac symptoms and to help predict their chances for an adverse event, according to a study published online April 27 in the Journal of Nuclear Medicine.  Discuss
Nuclear cardiology lab cuts radiation dose by 60%
May 8, 2017 -- A large nuclear cardiology lab was able to reduce its average radiation dose by 60% over the past eight years, according to new research presented on Friday at the International Conference on Nuclear Cardiology and Cardiac CT in Vienna and published in JACC: Cardiovascular Imaging.  Discuss
Molecular imaging shines new light on heart disease
May 3, 2017 -- European experts in molecular imaging expect the addition of cadmium zinc telluride digital detector technology, advanced quantification software programs, and novel radiotracers in SPECT and PET imaging will lead to major advances in research and clinical applications for cardiovascular disease.  Discuss
Low doses can make DSCT cardiac perfusion routine
April 25, 2017 -- The latest generation dual-source CT (DSCT) scanner cuts the radiation dose of cardiac CT perfusion enough to make it suitable for daily practice, according to new research. Expanded z-axis coverage and better signal-to-noise ratios can offer more information on myocardial blood flow.  Discuss
