New F-18 labeled PET tracer enhances myocardial innervation imaging
Cardiac PET imaging using the F-18 LMI1195 radiotracer was safe and effective in imaging abnormalities of the cardiac sympathetic nervous system, caused by increase in norepinephrine release and decrease in cardiac norepinephrine reuptake, according to a study in the Journal of Nuclear Medicine that enrolled 12 participants. The new PET tracer "demonstrates no safety concerns, rapid blood clearance, and extraction by the heart with stable myocardial activity over five hours and a favorable biodistribution for cardiac imaging over the same period of time," wrote Albert Sinusas and colleagues.

Higher dementia risk tied to sleep disturbance in veterans study
An analysis involving 192,266 veterans ages 55 and older found that those suffering from sleep apnea, insomnia and other forms of sleep disturbance were 30% more likely to develop dementia. The risk of developing dementia was 80% higher among veterans who also had post-traumatic stress disorder. The findings were presented at the Alzheimer's Association International Conference.

Experts seek uniform pediatric imaging standards
The Mayo Clinic and other institutions are calling for three standards to be implemented during pediatric imaging studies in an effort to protect children from unnecessary procedures and limit their radiation exposure. They say the practices should be required of facilities seeking accreditation, including hospitals and advanced imaging centers. (7/13)

Push for reduced taxes helps drive international pharma deals
A surge in mergers and acquisitions is having a profound impact on the pharmaceutical and medical device industries. U.S. firms are seeking lower taxes abroad, and some deals include foreign moves. Treasury Secretary Jack Lew has written to Congress urging retroactive adoption of tax changes that would discourage such deals, known as tax inversion.

CBO lowers estimate for federal spending on health care by 2039
The Congressional Budget Office slightly lowered its projection for federal spending on health care in 25 years, from 8.1% of the nation's gross domestic product to 8%. The government is expected to spend more on Medicare, Medicaid, the Children's Health Insurance Program and Affordable Care Act insurance subsidies due to an aging population and increases in insurance coverage. Cost control provisions in the Affordable Care Act are expected to hold back spending. The Hill (7/15), Los Angeles Times (tiered subscription model) (7/15)

Advanced imaging aids transition from "one-size-fits-all" to individualized medicine
The move to personalized medicine, in which diagnostics and treatments are based on an individual's biology and unique circumstances, is gaining momentum, and imaging is an integral part of delivering personalized care. Advanced imaging helps shape "precision" medicine by detecting and diagnosing problems earlier, targeting treatment, improving image quality and reducing radiation exposure. (7/12)

Poll examines patient preference on health reminders
A survey by analytics firm FICO revealed 41% of patients preferred phone calls as appointment reminders, while 33% chose e-mails and 12% chose text messages. Researchers also found 40% of respondents preferred using e-mails as reminders to schedule appointments and health checks, compared with only 23% for phone calls and 13% for standard mail. Mobile health applications and social media did not prove to be popular when it comes to such functions, researchers added. (7/16)
