A tiny molecular imaging system could be used on the field to measure brain injury or in the lab to capture individual molecules that betray the biology of cancer, neurodegenerative diseases such as Alzheimer's and viruses like human immunodeficiency virus (HIV). 

A PET/CT study followed 40 sufferers of heart attacks and just as many matched controls imaged with conventional coronary angiography and sodium fluoride PET/CT to gauge vulnerable plaques and see potential risk of heart attack.

Two novel cardiovascular PET agents are in the wings from FluoroPharma Medical, according to a recent profile in Forbes magazine.

A novel non-embyronic stem cell therapy is being studied to replace damaged dopaminergic brain cells in Parkinson's patients with their own cells in the hopes of restoring normal movement. 

New data regarding the prevalence of Alzheimer's disease is looming far and above previous estimates: 17 percent higher than previously thought, according to statistics from Alzheimer's Disease International.

South African Nuclear Energy Corp. announced this month that a leak has resulted in a global shortage of molybdenum-99, the precursor for Tc-99m used in a majority of molecular imaging scans. Authorities reportedly conducted an investigation Nov. 12 at the NTP plant in Pelindaba, just shy of 20 miles from the capital of Pretoria. It was estimated that the leak began Nov. 2. and was comprised of noble gas and iodine. Repairs are underway and the NTP plant will await independent review and authorization from the National Nuclear Regulator before operation can begin again.

The semiconductor photocatalysts known in molecular imaging as "quantum dots" are now being used for something completely different: alternative energy. The nanocrystals, instead of highlighting tissues, are harnessing methanol through a process of photosynthesis. This and other research, including advances in biomedical 3D printing and oncologic iron-based MRI contrast agents are featured in a profile of new research published in the New York Academy of Sciences magazine.

Human nature being what it is, physician participation in Medicare’s Physician Quality Reporting System (PQRS) will likely accelerate as the agency phases incentives out and penalties in. The effect may prove especially conspicuous since the bonuses have been voluntary and modest. By contrast, the forfeitures will be automatic and, if paired with other pay-for-performance requirements, impossible to ignore.
