Could cut use of angiograms and bypass surgery, as well as patient costs
Using positron emission tomography (PET) scanning rather than other types of imaging as the first tool to diagnose heart-vessel blockages is more accurate, less invasive and saves dollars, a study by University at Buffalo researchers has shown. The research findings were presented today (March 8, 2005) at the American College of Cardiologys Annual Scientific Session in Orlando, Fla.
Results of the study provide a rationale for PET scanning to become the initial diagnostic test for assessing a patients risk of heart attack, say lead researchers Michael Merhige, M.D., UB clinical associate professor of nuclear medicine, and Joseph Oliverio, UB clinical instructor of nuclear medicine who is a certified nuclear medicine technologist. Both also are affiliated with the Heart Center of Niagara at Niagara Falls Memorial Medical Center.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
