Study shows inaccuracies in cardiac PET-CT imaging

Current PET-CT scanners with standard commercial software designed to provide images of the heart are falsely indicating coronary artery disease in as many as 40 percent of patients, according to a study published today on the cover page of the Journal of Nuclear Medicine.

More fat may have some advantages for type 1 diabetes and heart disease

Researchers at the University of Pittsburgh Schools of the Health Sciences studying links between an early sign of heart disease called coronary artery calcification and body fat have found that, paradoxically, more fat may have some advantages, at least for people particularly women who have type 1 diabetes.
