Molecular Imaging

Molecular imaging (also called nuclear medicine or nuclear imaging) can image the function of cells inside the body at the molecular level. This includes the imaging modalities of positron emission computed tomography (PET) and single photon emission computed tomography (SPECT) imaging. How does PET and SPECT imaging work? Small amounts of radioactive material (radiopharmaceuticals) injected into a patient. These can use sugars or chemical traits to bond to specific cells. The radioactive material is taken up by cells that consume the sugars. The radiation emitted from inside the body is detected by photon detectors outside the body. Computers take the data to assemble images of the radiation emissions. Nuclear images may appear fuzzy or ghostly rather than the sharper resolution from MRI and CT.  But, it provides metabolic information at a cellular level, showing if there are defects in the function of the heart, areas of very high metabolic activity associated with cancer cells, or areas of inflammation, data not available from other modalities. These noninvasive imaging exams are used to diagnose cancer, heart disease, Alzheimer’s and Parkinson’s disease, bone disorders and other disorders. 

Exceptional responders may hold genetic keys to better cancer treatments

The National Cancer Institute has mounted a search for people who are dramatic outliers in their response to cancer therapies in an effort to improve treatments for common malignancies.

FDA draws up new regulatory strategy for research, pharmaceuticals and devices

Almost 50 percent of devices and 40 percent of medications administered in the U.S. are produced outside its borders. Around 80 percent of the producers of active pharmaceutical ingredients are internationally based and the speed of global research and commerce is swiftly changing. Clearly, the regulatory framework needs to keep up. With that in mind, the FDA is setting new priorities for the coming years. An official document has been drawn up by the FDA to that effect.

Angsty women in mid-life may be at higher risk for Alzheimer’s

Yet another risk factor for neurodegenerative disease has cropped up in recent studies: Worry among older women. Research conducted at the University of Gothenburg in Sweden provided a score on the scale of neuroticism for 800 women in mid-life and evaluated any potential links to Alzheimer's. Those who peaked on the anxiety scale were two times as likely to develop the disease.

Extreme altruists have larger, more active amygdalas

Altruistic people, such as those who would be willing to donate an organ to a stranger, show a stronger response to fearful faces in the form of a spike of activity in the amygdala when scanned using fMRI, according to a feature in the Discover D-Brief Blog.
