Medtronic Inc. announced clinical trial results showing that heart failure patients treated with its AdaptivCRT feature experienced a nearly 50 percent reduction in atrial fibrillation (AF) risk. Pioneered by Medtronic, the AdaptivCRT technology is a feature on certain cardiac resynchronization therapy-defibrillators (CRT-Ds) that continually adjusts therapy to a patient's natural heart rhythms and minimizes the amount of unnecessary right ventricular (RV) pacing. The results were presented as a late breaking clinical trial at the Heart Failure Society of America's 17th Annual Scientific Meeting.

At RSNA 2013, GE Healthcare will highlight the latest hardware and advanced applications for its Discovery IGS angiography platform. These updates are geared towards addressing the challenges of healthcare providers, support clinical decision making and helping clinicians in refining overall patient care.

Critical Diagnostics announced the clinical study, “Head-to-head comparison of two myocardial fibrosis biomarkers for long-term heart failure risk stratification: ST2 vs. Galectin-3,” recently published online in Journal of the American College of Cardiology (JACC) comparing the company’s cardiac biomarker ST2 to Galectin-3 (Gal-3), a biomarker from BG Medicine, found ST2 to be superior.

Ascendian Healthcare Consulting announced a new service line to assist clients with ensuring the confidentiality, integrity and availability of patient data — the medical imaging client’s privacy, data security and patient safety consulting services.

A study by Cutting Edge Information found that pharmaceutical companies measure cost per patient per month to allow trials of different sizes and durations to be compared easily. This measurement also helps to illustrate the high costs associated with delays.

CardioLogical Solutions announced that it has been issued two additional patents for its family of aortic embolic protection devices designed to prevent stroke and other ischemic complications. The new patents include its first issued patent for its Emboline CAP technology, the only aortic embolic protection solution to offer comprehensive arterial protection, as well as a further patent for its broad embolic deflector intellectual property portfolio. CardioLogical Solutions now has four issued patents for aortic embolic protection.

Helium, MRI

The U.S. Senate passed legislation Sept. 26 to reauthorize, extend and improve operations of the Federal Helium Reserve in Texas, which will guarantee a stable supply of the gas used for cooling magnetic resonance imaging (MRI) systems.

 
Ultraspect dose lowering software for nuclear imaging, SPECT imaging, reconstructions.
GE Brivo NM615 SPECT system can help lower SPECT nuclear imaging dose.

The highest levels of radiation dose in medical imaging are reported in nuclear medicine and pressure is growing for lower dose.
CTA, CCTA, CT angiography

A large number of emergency room visits are for chest pain evaluation, and many hospitals are adopting CT angiography as a primary test to quickly rule-out coronary disease.
