What Is A PET Scan? How Does A PET Scan Work?
A PET scan uses radiation, or nuclear medicine imaging, to produce 3-dimensional, color images of the functional processes within the human body. PET stands for positron emission tomography. The machine detects pairs of gamma rays which are emitted indirectly by a tracer (positron-emitting radionuclide) which is placed in the body on a biologically active molecule. The images are reconstructed by computer analysis. Modern machines often use a CT X-ray scan which is performed on the patient at the same time in the same machine.

Sebelius, DeParle Ready To Tackle Health Care Overhaul
The friendship between "working moms" Kathleen Sebelius and Nancy-Ann DeParle "could pay big dividends for President Obama now," USA Today reports. The two have a lot in common in the policy world as well. Sebelius, the secretary of Health and Human Services, and DeParle, director of the White House Office of Health Reform, "first met at the White House mess in 1997, during the battle for a patients" bill of rights to combat the constraints of managed care." Their relationship was then "built over a dozen years on topics ranging from the children"s health insurance program to raising their own children. Now, they are the "tag team for Obama"s most ambitious domestic policy goal: an overhaul of the nation"s health care system."

Food Prices In Developing Countries Remain High, Despite Global Drop

The U.N. Food and Agriculture Organization (FAO) on Thursday said food prices remain high in many developing countries because of reduced harvests, civil conflict and other factors, AP/Google.com reports (7/16). "Despite a drop in international food prices and good cereal harvests overall," current prices in several countries exceed 2008 highs or are at record levels, according to the "Crop Prospects and Food Situation" report, the U.N. News Centre reports. In 27 sub-Saharan African countries, FAO found between 80 and 90 percent of all cereal prices "remain over 25 percent higher than before the food price crisis two years ago," writes the U.N. News Centre (7/16). Reuters reports: "World cereals output was expected to fall 3.4 percent to 2.209 billion tonnes in 2009ò€¦ cutting [FAO"s] previous forecast by 10 million tonnes" (Kovalyova, 7/16). Despite the drop from 2008, which "saw the largest harvest ever, the report said that the outlook for world cereal supply and demand is satisfactory," the PTI/Hindu reports (7/17). According to the report, prices of the grain sorghum in Sudan "were three times higher in June than they were two years ago" and "maize prices doubled" in Uganda, Kenya and Ethiopia, "while in Southern Africa, they have dropped recently due to a bumper harvest but remain above pre-2007 levels," the U.N. News Centre writes. In addition to reduced harvests and internal conflicts, the FAO listed higher or delayed imports, strong demand in neighboring countries, devalued national currencies and higher transport costs as some of the factors contributing to the continued high price of food in developing countries. "The high food price situation continues to give rise to concern for the food security of vulnerable populations in both urban and rural areas, as these groups spend a large share of their incomes on food," the FAO report said (7/16). According to an FAO release, "Despite a positive outlook for global cereal supplies, 30 countries around the world are in crisis and require assistance as a result of natural disasters, conflict or insecurity, and economic problems." A summit that will address world food security is scheduled to take place in Rome, Italy, November 16-18 (7/16).
